XIAO ESP32-C3 and eInk expansion board

Products & Technology XIAO
#1

Hello!

I have used the eInk expansion board to control a 4-color ePaper with a XIAO RA4M1 board without any issues, but I can’t get it to work with a XIAO ESP32-C3.
Using Arduino IDE2, I can upload programs to the C3 when it’s not plugged into the expansion board, but after inserting it, I start receiving communication errors and can’t upload any programs.
I’ve tried manually putting it into BOOT mode, but I get the same error.
Am I doing something wrong? The eInk expansion board Wiki states that this board is compatible with the C3, but it’s not working for me.

Thankfully,
Ernesto.

HI there,

So I loaded up the Eink board with a C3 and downloaded the demo Zip from Git hub, Unzipped it and Opened with ArduinoIDE ver2.3.3 Selected XiaoESP32C3 and went straight for the upload , It compiled NO Errors and runs perfectly? Just as a Sanity check for you,
Note the BSP’s I’m using and Nothing Fancy.
