ESP32C3 CORE Development Board
CORE ESP32 core board is a core board designed based on Espressif ESP32-C3, the size is only 21mm*51mm, and the edge of the board is designed with stamp holes, which is convenient for developers to use in different scenarios.
The core board supports UART, GPIO, SPI, I2C, ADC, PWM and other interfaces, which can be selected according to actual needs.
