Matek Systems - AP_PERIPH CAN Node L431

Code: MTS-01-04-CAN-Node-L431

• 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.
