Hi, you can take the long road and read the full story, or feel free to skip it altogether and go to the juice.

The full story

Ok, I got my Raspberry Pi 2 from Build 2015 (thanks to the IoT team session) but I have a very narrow desk space, where no HDMI monitor will fit.

My home TV is far from the PC and I don’t have Ethernet connection there.

My first idea was to follow my dear friend Matteo Pagani and buy a WiFi universal adapter (the name sounds good for developing Universal Windows Platform apps J ) but I wanted to have my little Raspberry Pi near my PC, not in another room! I was searching for something more “cool”, something more transportable.

Then I’ve searched for LCD monitors to connect to the Raspberry, but:

  • Displays directly connected to the board were too small
  • I don’t think that a direct connection to the board can work without proper drivers, and due to the preview state of Windows 10 IoT Core
  • I don’t want to clog the board putting a display over it

Then I found it right on Amazon, a gorgeous 7″ display, with touch, from Sain Smart! With “Amazon Prime” send option, I compulsively bought it and two days later, it was here:

The kit arrived without documentation but I followed the video instructions found in the Sain Smart web site. I had two problems, one related to the touch connector and the polarity of the power connector.

The touch connector position on my device is slightly different from the one in the video, so I needed to check about those pins. More on this on my forthcoming post.

For the power connector polarity, I found good advice on a couple of Amazon buyer’s comments.

After setup, I was ready to turn on the power:

The LCD went to life showing the current video source. After some random click on the control panel button I found the on off button and the one to change the source, then I’ve changed to HDMI.

Beware that without a connected source, the LCD goes idle and turns off. It’s ok, it will wake up again as soon as the HDMI cable is connected and an input signal is detected.

Then I’ve attached the HDMI cable from Raspberry Pi to the LCD controller board and powered the Raspberry, crossing my fingers, and voilà:

Too good to be true, I can develop Universal apps for my Raspberry Pi 2 on my narrow work space, and have it right to my PC J.

The juice

You can buy it from Amazon or directly from Sain Smart.

It’s a kit consisting of:

  • HDMI+VGA+2AV Controller Board VS-TY2662-V1 (Support Automatically switch to AV2 )
  • 7 inch 800* 480 Lcd Panel AT070TN92 with Touch Screen
  • USB Controller Card
  • USB Cable

The control board drives the display, and you’ll attach the Raspberry HDMI output to the control board. This way you don’t need to install a driver, the kit act as a HDMI TV.

Follow the video instructions and be sure to use a 12 DCV power supply with positive polarity (+) inside and negative polarity (-) outside.

I still need to experiment a little more to say if touch works (more in another post that I’ll write shortly).

Make. Invent. Do.

With many thanks to Microsoft and all the IoT team!
