1. CAN-L4-3100 is a professional grade CAN Magnetometer based on RM3100 & ArudPilot AP_Periph firmware. 2. 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. 3. Equipped with the RM3100 magnetometer, this GPS sensor offers unparalleled accuracy in geomagnetic field measurement. Its high resolution ensures precise navigation and positioning. 4. Designed for efficiency, the CAN-L4-3100 operates on minimal power, making it ideal for sustained use in various applications without frequent battery replacements. 5. With its robust anti-interference capabilities, the sensor maintains strong signal integrity even in environments with high electromagnetic noise, ensuring reliable performance. RM3100 Geomagnetic Sensor CAN node MCU:STM32L431xC,256KB Flash Interface: CAN, DroneCAN Protocol UART2, MSP output (MatekL431-Periph fw) UART3, for external GNSS module debug, SWCLK & SWDIO LED: Blue, Fast blinking, Booting Blue, Slow blinking, working Red, 3.3V indicator Power supply for CAN-L4-3100 board:4.5-5.5V @5V pad/pin Power consumption: 22mA Operating Temperatures:-40-85℃ 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 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 . Put magnetometer far from power lines/ESC/motors/iron based material. equal 10cm 2 ears for mounting can be cut off ifyou don't need it. If the CAN wires are too long, bridge the "120R" jumper.
