The Seeeduino XIAO board brings you the power of a SamD21 in one of the smallest form factor. We have installed the Adafruit SamD21 bootloader.
Thanks to Node Blue, this board enables connecting buttons, switches, encoders, potentiometers, rotary switches, joysticks and various sensors.
By choosing the Bodac option, you'll be able to connect for example 11 buttons instead of 7 (a Bodac allows to connect 5 buttons on one input).
Attention, this board uses an USB-C connector.
