Matek CAN Node-G474 is an Adapter Node based on ArudPilot AP_Periph firmware.

With 5Mbit/s CAN transceiver and STM32G474 MCU, CAN-G474 is capable of CANFD.

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.

Firmware

  • ArduPilot AP_Periph  MatekG474-Periph for peripheral sensors
  • ArduPilot AP_Periph  MatekG474-DShot for DroneCAN-PWM output
  • Update via DroneCAN GUI Tool or Mission Planner–DroneCAN Tab, load “AP_Periph.bin
  • Update via STM32CubeProgrammer in DFU mode,  connect USB-TTL module to UART1, Plug USB while holding the DFU button in,  load “AP_Periph_with_bl.hex“.

Note

  • Just need to connect either one CAN bus to flight controller, or connect both to FC for redundancy.
  • SWC/SWD share MCU pins with SDA1/SCL1
  • Other MCU pins not specified are useless for now.
  • CAN-G474 support 1Mbit ~ 5Mbit CAN/CANFD,  CAN-L431 works with 1Mbit CAN.
