MSPM0G3507 Development Board

MPSM0G3507 core board
hardware configuration: 

Type-C interface for direct serial communication with a computer via data cable (onboard CH340N chip); 5V power supply
LDO linear regulator providing 3.3V power to the MCU;
40MHz and 32768Hz external crystal oscillator
; four LEDs (excluding the power indicator) that can be connected to the MCU chip pins via jumpers;
one user button (with hardware debouncing); one reset button;
no onboard debugger, connected to an external debugger via the SW pin.

Design concept:
      The circuit design is mainly based on the TI official M0 chip user manual and the MSPM0G3507 development board user manual (see attachments) for schematic drawing; some peripheral modules were removed while ensuring the MCU can work completely normally (compared to the TI official development board).
