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.

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.
