Introduction

    This is the MM32 main control board circuit with version number 1.5.2. This version removes the ADIS16470 from the main control board circuit and replaces it with an ADXL350 accelerometer, and adds a spare MPU6050 in case of accidents. This version also adds a Flash for the control MCU to store the track point data and a CH372C for the USB device function.
    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.
