Introduction

    This is the main control board circuit of the MM32, version 1.2.2. On this version of the main control board, a dual-mode, dual-band GPS module, an IMU module, an electronic compass and a 1.8-inch screen with touch functionality are installed. In this version, two MM32F3277G9s are used as control chips to work together.
    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.
