MSPM0 Development Board

This project is a custom-designed development board based on the Texas Instruments MSPM0G3507 microcontroller. The board was created to provide a compact and versatile platform for learning embedded systems, firmware development, sensor interfacing, and PCB design. It integrates essential hardware components required for standalone operation, programming, debugging, and communication with external devices.

The design features a USB Type-C interface for power and communication, a CH340F USB-to-UART converter for serial programming and debugging, and a low-dropout 3.3V regulator to provide a stable power supply to the microcontroller and peripherals. ESD protection has been implemented on the USB interface using the USBLC6-2SC6 protection device to improve reliability and protect against electrostatic discharge.

At the core of the board is the MSPM0G3507 microcontroller, a 32-bit ARM Cortex-M0+ based MCU that offers a rich set of peripherals, low power consumption, and excellent performance for embedded applications. An external 8 MHz crystal oscillator is included to provide an accurate clock source for timing-critical applications.

The board also integrates an LIS2DH three-axis accelerometer sensor, enabling motion sensing, orientation detection, vibration monitoring, and various IoT and wearable applications. The sensor communicates with the microcontroller through standard digital interfaces, making it suitable for experimentation with sensor fusion and real-time data acquisition.

Special attention was given to PCB layout practices, including proper decoupling capacitor placement, ground plane implementation, power integrity considerations, and signal routing. The design was developed using KiCad and includes complete schematic capture, PCB layout, BOM generation, design rule verification, and 3D visualization.

This project serves as both a learning platform and a practical embedded development board, allowing students and electronics enthusiasts to explore microcontroller programming, hardware design, sensor integration, serial communication, and low-level firmware development. The board can be used for educational purposes, rapid prototyping, IoT applications, motion sensing projects, and general embedded systems experimentation.
