Amazing DIY kit.

But first, know what you're getting into as this is an advanced kit. This is not a replacement for the bcm display that goes out to the hdmi and av. Instead, this is a GPIO project, if you don't know what that means, then this product might be out of your depth unfortunately.

The very nature of the rpi is exploration, and this kit appeals to this nature. It is a blast to play with and experiment on, and it might grind into you a few things you didn't know about the hardware on the rpi.

Here's some setup info and caveats.

Download the boilerplate code listed on the product page. At the time of writing this review, the same code was not located on the download section direct from the tontec website (that stumped me at first)

FOLLOW THE DIRECTIONS IN THE USER MANUAL
edit /boot/config.txt
change:
#framebuffer_width=1280
#framebuffer_height=720
to
framebuffer_width=480
framebuffer_height=320

use
sudo raspi-config

and set raspbian to auto-boot into x-windows. this isn't mentioned anywhere, but it's important that you do this because the device that x draws to is in turn going to draw to the GPIO.

also go to the advanced options and turn on SPI and I2C

Go to where you unzipped the code you downloaded from the store page and run
make

and for the final step copy and make executable the lcd file just built and make it start on reboot:
sudo cp lcd /etc/init.d
sudo chmod 755 /etc/init.d/lcd
sudo update-rc.d lcd defaults

then reboot.

So. a few notes. this is writing the x display to the GPIO. so the things that bypass x and draw directly to the bcm will not work. like omxplayer for example. or the GLES examples and such..

Posted an earlier review which was a major whinge aimed at Amazon rather than this product. The screen/case combo is handy. You need to take your time and follow the downloaded user manual. Some editing of device tree configuration needed - easy if you follow the instructions. On reboot, the screen was nice and clear - just don't forget it is small :-).

The case is a little loose fitting so I am Googling to see a good way of making it more robust. Otherwise, I am pleased with the Tontec product - it is just the Amazon packaging, description and price which was disappointing.

This isn't a plug and play device. For best results install Notro's TFT drivers. It took me less than an hour to assemble the case and install drivers. Supplied instructions worked fine. Getting the touch function to work is a little more involved, but still pretty straightforward if you're familiar with Linux. I added a mini Bluetooth Keyboard/Mouse and a slimline USB battery.

So I have a Tontec 3.5 Touch screen from the wonderful makers Tontec for my Raspberry PI B+ model. The first screen that was sent was faulty, however Tontec rapidly distributed another within two days from their warehouse (exceptional service).

The instructions that come with the Tontec and if you tried to follow them were not complete and the Touch screen would not work, hence I have added in the missing config and hope that you too have your touch screen working within 30 minutes.

Tontec 3.5” Screen Driver Install Instructions - Model: MZ61581

Bellow you will find instructions for installing the appropriate drivers for the Tontec 3.5 inch screen on your Raspberry Pi (including Pi 2). This guide was written for Raspbian wheezy, specifically 2015-02-16-raspbian-wheezy.img, though the guide should work on later versions as well.

1. Initial Config of New Raspberry Pi Install
After booting your Raspberry Pi for the first time on Raspbian-Wheezy, we will need to perform the normal tasks of setting up our Raspberry Pi. E.g expand filesystem,
Then we need “update” and “upgrade”
2. Update Firmware
We now need to update our firmware to the newest version to support Tontec screen
3. Enable SPI and set overlay for Tontec MZ61581 Screen
Open /boot/config.txt
And add these lines to the bottom
3a. Make sure that Auto boot to X Windows is enabled by going into sudo raspi-config
3b. Also while in raspi-cong make sure you turn on SPI and I2C, as the Touchscreen will not work without this enabled
3c. edit /boot/config.txt and change #frame buffer_width =1280 to 480 and remove the # from the beginning of the line
3d. edit /boot/config.

This is really cool - bought it to build small interactive apps with just a couple of large button on the screen for a Raspberry Pi 2. The screen perfectly fits that sort of use. The box is OK and reasonably easy to put together. Installing the screen is clearly not plug and play, but the instructions are very clear, and it all went without any issue for me. Now have a nice little box to build things with :)
