• CAN-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,

Rangefinder, Proximity sensor, Electronic Fuel Injectors and GPIO based (PWM, 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.
