Turn your Pi into a Tablet! (RasPad 3.0 Review)
0 literally. A touch screen with a raspberry pi inside of it sounds pretty useful, but is it im going to answer that question in this video press start whats up smart homers? This is aaron in this video im. Going to show you the razz pad 3.0 im going to show you how to assemble it, how it works and some of its features and if its even a good idea in the first place, full disclosure. The seller did send me this product for a review. Initially, i was going to turn them down, but after reading some of the documentation about some of the features and use cases for it, it may be just the piece of tech that i need to solve a problem that i have im going to get into that At the end of this video, as always im going to tell you exactly how i feel about this device despite having been sent it for free, so lets, look at the design. The razz pad 3 supports a raspberry pi 4, but it does not come with one. So youre going to need to pick one of those up as well. The unique wedge shape. Design of this device is not just for looks its necessary in order to make space behind the screen for the raspberry pi and allow for efficient cooling. The wedge shape also allows for the tablet to stand up on its end, as well as lay down on its back, giving you two different extreme angles for it to rest.
I found that the angle that it rests on while its lying on its back is just a little bit too shallow for me to look at while im sitting at my computer desk. Obviously i could just raise my chair up a little bit higher and i could see it better for external ports. The razz pad has an ethernet port, three usba ports, an hdmi port, a headphone jack and a dc power jack on the opposite side of the tablet. It has battery and power indicators, a power button volume and brightness controls, and a micro sd card slot on the back are some holes to allow for sound from the internal speakers to escape and also to allow airflow through the case, there is also a slot for A raspberry pi cameras ribbon cable to fit through if youre wondering about gpio access. There is a slot in the top edge that allows for the use of a ribbon cable to bring the gpio pin access outside of the tablet body. Obviously, the main feature of this device is the display, in my opinion, its really nothing to write home about. It has a 1280 by 800 resolution and with a physical size of 10.1 inches. It looks pretty good, but nothing special. The touch interface is pretty nice, with no false touches or mistouches. In my experience, the assembly of this device is pretty straightforward: youll need to bring your own pie and then follow the assembly.
Instructions found on the razpad website when you open up youll, see a motherboard inside as well as a button board which has all the external buttons on it. Theres, also a bunch of mounting holes for the raspberry pi. The sd card, cable, which comes with the tablet, needs to be attached to the pi and then attached to the button board. Then the pi can be screwed into place and the ethernet usba micro, usb and usbc cables can be connected after that theres a little accelerometer that can be slid onto the pis gpio pins. I never needed to solder these. I just slid them into place and they stayed, and i didnt have any issues with the accelerometer. This accelerometer is necessary for the auto rotate function that you set up later. After all, the cables and the accelerometer installed. The fan can be mounted to the back of the case and then plugged into the appropriate spot on the motherboard before closing up dont forget to add the heat sinks to the raspberry pi, to make sure its getting cooled properly after assembly youll need to use a Raspberry pi os installer to install the raspberry pi os on the sd card. These instructions are all given on the razpad website. The tablet functions pretty much as you would expect a raspberry pi to function after assembly. You can follow the instructions on the razpad website in order to install an on screen keyboard, the auto rotate function and a right click function.
The on screen keyboard works pretty well, but it doesnt have any of the swipe features that you would be used to with an android tablet. Of course, it worked pretty well with occasional, missed touches on the space bar, but the main issue being that the keyboard does not auto display when you click to edit text in any text field, its only showing up in some of them and thats a big problem. Theyre going to need to work on that, the auto rotate function works pretty well, in my opinion, allowing you to view the display upside down right side up in both portrait and landscape modes. There is a brief black screen when you rotate it, but nothing that really would stop you from being able to use the tablet at all. The right click feature is a little gimmicky, its supposed to display a menu when you long press say, for example, the desktop. However, if the touch surface is too big like if youre using your thumb, then it could not register the right click. I really dont find this feature very useful, but some people might the display works pretty well, but it doesnt get as bright as some of my other android and windows tablets, its good enough for the dark of my office, where im going to be using this most Of the time but out in the sunlight, it gets a little bit harder to see. That also could be because of the viewing angle.
The tablet runs pretty quiet, but you do hear the cooling fan sometimes which you obviously dont in a standard android tablet. So what do i plan to use this, for my plan is to install octoprint on the raspberry pi and then use that to remotely monitor and control. My ender 3 3d printer ive actually already done this, but this will probably be something for a future video. On top of octoprint, octodash can also be installed, which is used to display a nice graphical user interface on top of octoprint after installing octodash, the touchscreen automatically works with this razz pad, and i can use the touch interface to control my 3d printer. In my opinion, the biggest consideration youre going to need to make when youre looking at this device is the price. I really dont think the price of this unit 220 u.s – is really worth it. If youre only planning to use this as a smart home dashboard, if youre looking for a tablet that you want to use to display home assistant on, i recommend you check out one of my other videos where i showed how you can use a fire tablet. Hd to do that, that is 10 times better than this. I also wouldnt recommend you run home assistant directly on the pi inside of this. Although there is a guide on how to do this on the razz pad website, it just doesnt seem like its really worth it just run on a pie.
Without this, you really dont need a display for a device thats running home assistant, where i think this device really shines is for diy uses like octoprint and gpio programming anyway thats all. I have for you guys in this video.
