cpNode Xiao
cpNodes are Arduino-ecosystem nodes created by Model Railroad Control Systems' for the Computer Model Railroad Interface (CMRI) system.
The Xiao variations by SPCoast use the ESP32 family of microcontrollers, and communicate with each other and with classic C/MRI nodes via CMRInet. These controllers also support WiFi and Bluetooth for future protocol development.
