Raspberry Pi 4 Tablet: RasPad 3 by Sunfounder – Full Setup and Review!
. This kit turns your raspberry pi 4 into a tablet. It has a 10.1 inch, touchscreen display and built in battery, which makes it a convenient and portable solution for all kinds of projects, including retro gaming. Well, unbox it set it up and try it out with a number of operating systems. Lets get started. Music lets briefly talk about the features of the rest pad 3. It has a 10.1 inch touchscreen at 1280 by 800 pixels. The display can be set to extend mirror and, of course, it can rotate from landscape to portrait mode automatically. It has a built in battery which they state will last up to five hours, most likely, depending on the amount of i o operations and display brightness. It does have built in speakers slots for the gpio and camera. There are three usb 3.0 ports, a full size. Hdmi port and easy access to the microsd, the audio and ethernet ports. Im really interested in checking out the raspat 3. sunfounder had contacted me some time ago asking if i would be interested in reviewing this product after checking out their website. I was definitely intrigued with the product and agreed to review it keep in mind. All opinions are my own and i will provide you with my honest feedback about what i like and what i dislike about this device. I will say the included documentation is a little bit weak in that it only provides a simple flyer that shows you how to assemble the unit.
It was at that point. I checked out their website in more detail and yeah. I mean its got a treasure trove of information thatll help you really make good use out of this machine and well be going over some of that information in this video as well lets go ahead and get it out of the box theres the rest pad three. Well, just set it off to the side and see what all is in the box. Weve got. Uh looks like the power brick and its using a barrel connector at 15, volts 2 amps, 30 watts and heres the power cable for the brake, and this was pretty nice. It included a screwdriver which has a flat head as well as a phillips head and its magnetic too, and has the res pad logo there. These two pieces are for the sd card and the screen rotation. Well, look at that in a moment. Of course, the fan for keeping your raspberry pi 4 cool and they included the heat sinks, which is very nice. All the cables to plug in the pi are here your usbc, the usbc cable, a micro hdmi to micro, hdmi, and you actually have two of them ones longer than the other, and you also have this rj45 ethernet cable extension. Additionally, you get this usb 3.0 mail to mail, cable and dont worry ill. Show you how to hook all this stuff up its very easy lets, go ahead and take the rest pad 3 out of the package.
On the left hand, side you have your led battery indicator, the brightness and volume controls, as well as your power button and, of course, a micro sd slot, which is easily accessible on the bottom. There are four ventilation slots and, on the back, you have a location where the gpio cable can be fed through, which is a very nice touch. You will, of course, also need to pick up the raspberry pi 4 separately. It is not included in the package. Well, take a quick look at the ports here. You have your usb port, 2.0 and 3.0, your ethernet jack. This is uh your gpio header, pins, the display port, the camera port, and if we turn it over here, you can see the usbc input for your power to micro, hdmi, ports, your av jack and the slot for the micro sd card now lets put it together. Music to keep the display from getting scuffed up im going to use this packing material that was included in the package. You could use a towel well, go ahead and flip it upside down and use this handy, dandy, razz pad screwdriver and unscrew all five screws. Well, pry it open, which is very easy. On the right hand, side you have the main i o board, which all the cables will connect up to this, with the exception of the sd card along the back side, you have your battery thats, going to be used to power this device and, on the left Hand side you have the button array as well as a slot for your external micro sd card connection.
On the left hand, side we have the three buttons, as well as the sd card slot, and on the other side we have the power, the av jack, a full size, hdmi, three usb 3.0 ports, which is nice and, of course, ethernet. Im gon na go ahead and apply the heat sinks to the raspberry pi 4. The usb controller, the smaller one, goes on the far right. The middle one is your ram and the larger one is your cpu. I want to show you real quick how the sd card adapter plugs in. Basically, you have this ribbon cable and you just slide the other end into the sd card slot, like so, but its actually easier. If you just install the ribbon cable first like that and push down on the black connector and then just pop it into the raspberry pi, 4. and next well, just go ahead and install the four screws into the pi, just like so using our handy dandy. Rasp, head screwdriver, this little guy is the sensor that handles the screen rotation. So if your screen doesnt rotate, maybe you forgot this step. You just slide it into the pins, as you see here at this point, its simply a matter of plugging everything up so well start out with the rj45 ethernet connection and go ahead and plug that in on both ends. Well, do the same with this usb 3.0. Cable, keep in mind. The cable is rather stiff and you will have to bend it just a little bit to get it to fit in properly and now well, plug in the two hdmi cables.
Well, start off with the shorter of the two and plug it into the one furthest to the right, and it just slides right in and then do the same over here on the right hand, side and well take the longer of the two micro hdmi connectors and Plug it into the port on the far left and plug it into the right hand, side position all the cables on the other side of this notch, thats very important. Otherwise, itll interfere with the screw hole which you dont want, and the last cable we need to hook up is the usbc connection for the power and well go ahead and plug that, on the right hand, side as well and again make sure that your cables are Arranged like this and theres, nothing obstructing the screw hole now well install the fan. You want to place the label side down and then take the four screws that have kind of a flat headed ring to it and screw those into the assembly. Here then plug in the other end of the keyed fan connector into the i o board were just about done with the assembly. We just have to close up the case and then reinstall the five screws. I started with the middle and then worked my way around in the next segment. Well, turn our attention to the software and operating system setup and configuration Music. Sun founder includes a pre made image of raspad, which were going to install to a microsd, but first im going to show you how to get the raspberry pi imager go to raspberry pi dot com forward, slash software to download the raspberry pi imager.
There are a number of operating systems you can use it with, for example, windows, mac, os, ubuntu and, of course, the raspberry pi itself. In this example, im going to download and install the windows version then head on over to razpad.com, pagesrezpad.os and download the rest pad image its about 6.6 gigabytes. So give it a little bit of time once downloaded im going to go ahead and right click the file and go ahead and extract it using 7 zip. Although you dont necessarily have to do this, the raspberry pi imager will allow you to simply select the zip file with the image extracted well load up, raspberry pi, imager and click choose os. There are a number of operating systems you can select and install to your micro sd card, including raspberry pi os and the imager will both download and install the image to your micro sd card. However, in this case, we want to write the image that we just downloaded for that well, move down to use, custom and select our image and click open then well choose our micro sd card, which in this case is 128 gigabyte, micro sd and then simply click The right button to write the image itll ask us, if were sure: well click, yes, and the image will be installed once its written just click the continue button and close out of raspberry pi imager. Now that we have rest pad os written to our micro sd.
Well pop it into the rest pad itself, just like so im gon na go ahead and remove the screen cover, then press and hold the power button until you see the leds turn on takes about eight seconds or so. At this point, the operating system will begin to boot and youll have a pre setup image with many of the features the rest pad provides. For example, you can easily rotate the screen and the display will adjust automatically if you didnt install the gpio cable through the slot there. You can also use it as a stand. Ive heard some mention that the fan is too loud, but i did encounter that as an issue. There are a number of applications pre installed. For example, if i switch over to office, you can launch libreoffice writer and use it to type in a note of some sort, in this case ill pop up the keyboard by clicking the icon in the upper right and then just type in something and adjust the Font size very cool if you close it out: itll resize the display so yeah thats, pretty cool ive loaded, chromium, the web browser and went to wagners, techtalk.com and yeah it browses just fine. I also downloaded a number of magpie magazines, which i highly recommend. If youve never seen it lots of great information and project ideas spanning all the raspberry pi models, another thing you can do, of course, is to pinch and zoom, and that works very well and with the three provided usb ports, if you want to plug in a Dongle or a usb keyboard of some type like this re i4 mini bluetooth keyboard.
You certainly can i also found that the stand i used for my fire 10 tablet works perfectly with this device. All you have to do is adjust it up and the raspad 3. Just sits on it perfectly check that out ill leave, a link down below if youre interested all applications seem to work very well and the touchscreen was very responsive. Even with this calculator and the very small buttons i didnt have any problem entering the numbers. If you enjoy tinkering with electronics, you can easily add a gpio, cable and breadboard, then using scratch python or your favorite programming language. You can do some amazing things, given that this is a raspberry pi. You can easily install many different operating systems such as raspberry pi, os twister, os ubuntu and many more well start with pi os on the res pad website. Youll find all the instructions you need to set up. The keyboard screen rotation its very easy to do and ill show you how i installed a fresh copy of pi os and connected it to my network, then plugged in a keyboard and mouse, then go into preferences and launch raspberry pi configuration and then select the interfaces. Tab and go ahead and enable ssh ill use putty to connect to the pi. So i can easily show you the steps from my pc. You can, of course, open a terminal on the pi and do all this without remote connecting ill start by installing the virtual keyboard simply copy and paste.
Each of the commands into the terminal session now well do the same for the right: click on the rest pad again just copy and paste each of the commands into the terminal towards the end. You will need to modify the rc.local file and add a single line. So, im just going to paste that in right here then press control x to save y to yes and enter to save the file now type in sudo reboot and go ahead and reboot. The raspberry pi and the last piece well install is the screen rotation service. So again, well just log in as we did previously and then just copy each of the commands and run them inside this terminal session. Once done. Press y and the machine will reboot now well move back to the raspberry pi and go to preferences and onboard settings. Here you can customize the look and operation of the keyboard. There are also options for adjusting the transparency. It is very configurable, so definitely spend some time exploring the settings as an example lets go back into libreoffice writer and youll see the keyboard popping up notice. It did so automatically. I didnt have to do anything special after youre done typing into a text field address bar, etc. You can configure the keyboard to auto hide, which makes this a very nice user experience. Of course, we need to make sure the screen rotation service is working properly and, yes, it is now lets flip it back horizontal and there we go.
I already went through the setup steps for twister os, which happens to be my personal favorite os for the raspberry pi here ill load up, photogimp and well see how responsive the touchscreen is for drawing on the screen works very well. I configured the keyboard a little bit differently under twister os. Just to show you a couple of different ways. The keyboard can be configured so well, go ahead and go back into libreoffice writer and the keyboard will pop up and youll notice, its more transparent here and theres also suggestions up at the top. Also, on the right hand, side there is a small icon which will allow you to easily move the keyboard up and down, and you can see how its transparent as its moving up and down over the document. Twister os also has retropie pre installed, so lets check it out with a few games heres one i used to sink a lot of quarters into when i was a youngster, thats, galaxian and now well. Look at super mario brothers on the nes clay is great and lastly, for a retro pie. Example well check out tekken 3 on the playstation. You can also install the screen rotation service in ubuntu, and while it works its not as responsive as it is in pi, os and twister os now lets take a quick look at other ways. You can use the rest pad 3. Music retro gaming is likely. One of the most popular use cases for the razzpad 3.
check out my setup guide for retropie, recall box and bottocera at the link below you can also extend or mirror the display using a full size, hdmi, cable and turn your respat into a nice desktop computer. When it comes to 3d printing, yes, you can even use the rest pad 3 with your 3d printer, in this case im using a flashforge creator pro and have the rest pad 3 connected via usb cable to the back of the 3d printer with octoprint software installed. This allows me to easily monitor a 3d print and remotely access a print job. Another fun use case for the razzpad 3 is to use it for robotics programming. In this case, i used it with a micro bit based robot, and i have a detailed guide and video at wagners tech talk, dot com forward, slash, mcqueen, plus there are a lot of great project ideas available on their website. One that looks particularly interesting is using the res pad as a home assistant. Let me know in the comments below, if youd like, to see a follow up video demonstrating how to set that up. That brings us to the end of another video lets talk about the things i like about the razz pad 3., first off its a very portable raspberry, pi 4 solution, in fact its the most convenient raspberry pi 4 device i own at the present time. I really like the fact that it has a full size, hdmi port, which makes it easy to connect up to a tv or monitor the auto screen.
Rotation works decently. Well, the 10.1 inch touchscreen works great and is very accurate. There were no issues there. You also have access to all of your. I o ports that you may need, so it makes it great for developers hobbyists, retro, gamers or pretty much anyone. It was hard thinking of things that i didnt like about this unit. However, i would like to see an improved battery life. While i was able to leave it running for several hours. A lot of i o operations will begin to drain the battery, so keep that in mind. Lastly, they no longer include a printed manual in the package. I personally would have preferred to have a printed manual. I hope you enjoyed this video on the rest pad 3 and found it helpful.
