AP_PERIPH CAN MAGNETOMETER RM3100

• CAN-L4-3100 is a professional grade CAN Magnetometer based on RM3100 & ArudPilot AP_Periph firmware.
• RM3100 sensor technology provides high resolution, low power consumption, large signal noise immunity, a large dynamic range, and high sampling rates. Measurements are stable over temperature and inherently free from offset drift.

  • 3D File CAN-L4-3100_step.zip 
• Firmware
  • ArduPilot AP_Periph: MatekL431-GPS  or MatekL431-Periph
  • Update via DroneCAN GUI Tool or Mission Planner (AP_Periph.bin)
  • Update via STLink (AP_Periph_with_bl.hex)
• Parameters
  • CAN_P1_DRIVER = 1 if attached to CAN bus1 port or CAN_P2_DRIVER = 1 if attached to CAN bus2 port
  • COMPASS_AUTODEC  = 1

Packing

• 1x CAN-L4-3100 board
• 1x JST-GH-4P to JST-GH-4P 20cm silicon wire

Tips

• CAN-L4-3100 is pre-installed with “MatekL431-GPS” firmware.
• MSP feature is disabled in “MatekL431-GPS”.   If you want to use MSP feature,  reflash it with “MatekL431-Periph” firmware(AP_Periph_with_bl.hex) over SWC/SWD pads via ST-LINK.
• Put magnetometer far from power lines/ESC/motors/iron based material. >=10cm
• 2 ears for mounting can be cut off if you don’t need it.
• If the CAN wires are too long, bridge the “120R” jumper.
