Features:
1. The core board is a core board designed based on ESP32-C3, with a size of only 21mm * 51mm;
2. The board edge adopts a stamp hole design, making it convenient for developers to use in different scenarios;
3. The core board supports interfaces such as UART, GPIO, SPI, l2C, ADC, PWM, etc., which can be selected according to actual needs;
4. The minimalist version is suitable for mass production. For personal development and debugging, it is recommended to purchase classic models with good compatibility and easy development;
5. Multi functional, the development board supports diverse development methods.
