Packing

• 1x CAN-G474 board
• 2x JST-GH-4P to JST-GH-4P 20cm silicon wire
• 1x JST-GH-6P to JST-GH-6P 20cm silicon wire

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.
