Introduction

    This is the MM32 main control board circuit with version number 1.3.3. In this version of the main control board, an MM32SPIN27 microcontroller is added to read data from the geomagnetometer and IMU and to perform preliminary processing of the data. Also, the geomagnetometer was changed from HMC5883 to RM3100.
    This board is designed with a four-layer board and uses the JLC7628 laminate structure for 50-ohm impedance matching of transmission lines. Since the PCB is designed with a direct connection to the power supply copper cladding, it requires a relatively long heating time for the solder tray to be tinned during soldering. Care needs to be taken not to have false soldering when soldering.
