M2CB-STC32G

This core
version is based on the STC32G design and is inspired by the official Dragon Slayer development board.

Based on: STC32G12K128, 32-bit 8051 core (1T), approximately 70 times faster than traditional 8051.
Supports: UART, USART, ADC, advanced PWM, SPI, I2C, I2S, USB, CAN, LIN, RTC, DMA, etc.
IC: Onboard STC32GMCU, CH343P, M34E04
Interfaces: Onboard TYPEC, expansion header, 8-pin TFT, IPS screen interface, DIY M&M-Key M.2 interface
Supported programming platforms: ARM, Keil, etc.
All I/O ports have
two WS2812 LEDs. Reserved
8-pin TFT, IPS, SPI screen interfaces (note I/O conflicts).
