The AP_Periph CAN Node L431 allows you to easily connect multiple ardupilot peripherals via this node to act as a hub between your sensors and the flight controller. This is ideal for some smaller flight controllers that do not have as much I/O.
Features
CAN-L431 is an Adapter Node based on ArudPilot AP_Periph firmware.
With this board, you can easily utilize the ArduPilot driver library to convert ArduPilot supported GNSS, Compass, Barometer,Airspeed sensor, and GPIO based (PWM, Buzzer/LED notify) peripherals to DroneCAN bus peripherals.
