Technical summary
ESP32-C3 dual USB port description:
This board is assembled with an original ESP32-C3 module from Espressif, with 4MB of Flash (ESP32-C3-MINI-1-N4). It is a general-purpose Wi-Fi + Bluetooth® LE MCU module that integrates complete Wi-Fi and Bluetooth LE functions.
Most of the module's I/O pins are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount the module on a breadboard.
There is a WS2812 RGB LED connected to IO8. It has a red, a green and a blue LED which are individually addressable. There are many examples on the Internet showing how to drive a WS2812 LED. For example, search Google for "WS2812 Arduino" or "WS2812 c code".
There are two USB C connectors. One is connected to the USB peripheral of the ESP32-C3 chip. The second is connected to the UART of the ESP32-C3 module via a CH340 virtual COM port.
