If you’re having trouble with magnetic noise affecting your flight controller’s on-board compass, you may want to switch to an external compass that you can mount further away from noise sources such as motors, ESCs and your power distribution system.
CAN-L4-3100 is a professional grade DroneCAN Magnetometer based on RM3100 & ArudPilot AP_Periph firmware. This dedicated magnetometer helps to eliminates any noise in your magnetic field measurements for accurate heading and orientation calculations, allowing your to drone to navigate through waypoints accurately. 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.
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.
