XIAO ESP32C6
From Wildsong
Seeed Studio description is here: Xiao ESP32C6
Now I need to figure out how to program one of these, and how to make it talk to a 24GHz mmWave Sensor for XIAO.
GPIO01=TX=pin 10
GPIO02=RX=pin 11
GND=pin 2
3V3=pin 3
One reason I find this controller of particular interest is that it supports Zigbee and Matter.
Xiao controller series comparison -- Seeed Studio has a plethora of Xiao boards with different processors.
