Control Board Circuit
Introduction
This is the MM32 main control board circuit with version number 1.0.1. On this version of the main control board, a dual-mode GPS module, an IMU module, and a 1.8-inch screen with touch functionality are installed. On this circuit version, there is also a servo power supply, an electronic switch and a 5V power supply designed to provide power and control signals for a servo and a brushless motor.
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.
