Hi Dennis,
yes, the board looks similar. Of course I powered with a separate power
supply :-)
That's my board:
https://www.ebay.de/itm/174109565997
Works fine on Windows PC, so it's not defective.
I like it, brilliant colors, wide angle .... but Beaglebone Black is
ignoring the touch.
I'm using the current IOT Debian buster image.

The project requires the pru units, that works fine.
Touch is eating up my time. And I expect it makes no sense to order other
touch displays and the status is still the same.
USB based touch was expected as "best and simple" solution. I need SPI and
GPIO for surrounding hardware. That works fine.
HDMI is required to have the possibility to connect "any" monitor. There is
1m distance between BBB and display.
RPI is not an option for me, because I need the PRU's.
Thanks for help
