Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

please read the full threat before destroying your picos ;-)

I have only connected GND pins because they are left side to right side at the same relative positions!

Additionally I connected VSYS (WebMite) to VSYS (RP2040LCD) and GP01 (WebMite) to GP00 (RP2040LCD) and GP00 (WebMite) to GP01 (RP2040LCD).

ALL OTHER PINS ARE NOT CONNECTED (I dragged out the header pins after soldering GND pins!)

Watching the serial communication on PIN GP01 (RX) of the RP2040LCD (receiver)
It seems to show the starting of a communication.
