also disabled in MatekL431-GPS fw for reducing the data flow. MSP feature is also disabled in MatekL431-GPS fw before Jun-6-2023.
If you want to use MSP feature, Pls flash it with MatekL431-GPS (AP_Periph_with_bl.hex) fw version after Jun-6-2023 over SWC/SWD pads via ST-LINK.
From mid-July-2023, the 25mm patch antenna changed from Taoglas to Cirocomm PA025AZ0009. Both antennas perform the same.

M10-L4-3100 is based on ArudPilots AP_Periph firmware, It is a GNSS+COMPASS+BAROMETER peripheral with CAN/DroneCAN and UART/MSP interfaces.
M10-L4-3100 uses multi-constellation GNSS powered by M10 series , It is a concurrent GNSS receiver which can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture all four major GNSS constellations, GPS,Galileo, GLONASS and BeiDou can be received concurrently.
M10-L4-3100 integrates an industrial-grade compass PNI RM3100 which provides high resolution, low power consumption, no hysteresis, large dynamic range, and high sampling rates.
