ESP32C3-CORE Development Boardpay attention:The classic model (version with TTL serial port to USB) must install the CH343 driver to download the firmware normally. The default CDC driver can only print the log, but the download will fail if the speed is too slow. drive portal

The new model (USB direct connection) can be burned directly without installing the driver. You can use Luatools to burn normally, but cannot use LuatIDE. There is no difference except that the firmware with the word USB needs to be selected when burning.

1. Product descriptionThe CORE ESP32 core board is a core board designed based on Espressif ESP32-C3. The size is only 21mm*51mm. 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.
