MSPM0G3507 core board

The MSPM0G3507 core board is pin-compatible with LCSC's Dimensity Components, has a smaller size, and also features an SPI interface for connecting to an LCD screen. This core board was created for the 2024 National Electronic Design Contest; after the contest, we open-sourced this core board and its baseboard.

The schematic and PCB design describe
the use of a CH340 for the serial port. The serial port pins are not exposed; connection is only possible via USB.

An 1117 power supply is used primarily for its affordability and ease of soldering.

The SPI interface is brought out for connecting to the LCD screen. Two attached images are

shown. A quick note: during the competition, one of the judges immediately asked me if it made sense for us to buy a ready-made board, and whether I thought this was a good practice for our competition. I almost died laughing. I explained that this was our lab's board, with my LCSC logo on it; it was a question-and-answer format. He asked me about the crystal oscillator frequency, and after I answered, he said to the person next to him, "This is the baseboard you designed yourself." I asked him if he had anything else to say, and he replied, "Don't say anything, I already know." I almost died laughing.
