Review on GeeekPi Capacitive 800X480 Raspberry BeagleBone by Auden Paz

Revainrating 4 out of 5

Worked with Raspbian on a Pi Zero but had rotation issues.

First, the display is sharp and clear. The touchscreen worked with the latest version of Raspbian on the Pi Zero. This is a better choice (easier to use/integrate into my project - building my only phone) than using a 3.5" TFT display, which would otherwise be connected to the Raspberry Pi's GPIO pins. I'm integrating with a custom Linux distribution (PiBox) and found that I need to download the hid_multitouch driver for Linux to make it work on my distribution. I love this little display so don't take the following comments as negative - just informative. There is a cable from the screen to the circuit board. which I hit with my thumb when I connected the OTG cable. A slightly wider board would fix this, or find a way to tuck the cable more under the screen. It would also be nice if the HDMI and USB connections were routed under the board instead of the board to reduce the number of cables protruding from the board itself. however, not required if the X.org tslib driver is used - this is only required if your application uses tslib directly. The rotation (via config.txt) works, but the portrait display is half the size. Maybe I'm not doing it right. I just set either lcd_rotate=1 or display_rotate=1. The first one gets the loading screen rotated around the X indicator, no. The latter is both rotated. I haven't tried rotating X with xrandr yet. The OTG connection is hard to compare to the Pi Zero cable, which is also OTG. You can get an OTG hub for the Pi with Type A female connectors and then a Type A male to OTG cable to connect to the display. When you're ready, Adafruit has some tiny OTG wireless connectors that you can plug in manually to power off the hub.

Pros
  • Rugged design
Cons
  • Modern
