Have a fingerprint sensor that I am attempting to connect to a XIAO, the pin diagram/chart on the manufacturer’s website uses a larger Arduino with more pins, currently have the the following config but there’s no output from the device:
VCC - VCC
GND - GND
TXD - 7
RXD - 6
RST - 9

Hi,
Have you tested that the same wiring and code will work on other models (such as uno or other boards)? Or is your piece of xiao able to run other programs?
Please provide more information, it is crucial for me to find out the problem! btw, Saturday and Sunday are Seeed’s days off and we may not respond to emails
