Hi, rolftest99
I have the same hardware. I can't found how install firmware on xiao.
Using basic32.com install from web page not work, xiao in boot mode (I think), orange led flash and UF2 disk appear.
I also tried to downloaded zip for Esp-C3, copied the three .bin files on uf2 driver but never occour.
Can you help me?

EDIT: sorry, I have samd21 version, not esp32 !!

Hi nid69ita,
a .bin file don't work direct on uf2. You must program the XIAO-Esp-C3 with the webinstaller on Basic32.com or you must ask Roby to give you his nice Flash.bat file for esptool.py to flash! When i see it right it isn't on basic32.com or Roby?

I removed it because I thought it was no longer needed, I'll put it back in the download folder if it can be useful

The xiao Expansion Board works very fine with the ESP32-C3!
A lot of the GROVE (I2C) modules can test of a very simple way!
No soldering required!

So I'll put it in the compatible boards. I wanted to make a list so I could know which ones have been tested and are working.
