Are you planning on making a PCB with this?
have you bread board tested the circuits?
Xiao ESP32S3 is a good choice, However the dual cores don’t really work that way.
Do you have code to support this Device?
The components look fine, WHy so much drive or switching on the LED’s?
So is the total size is 20 x 50 mm?
Is that the case or the board dimensions?
Check out the Post I put up on a PC board for xiao,
