ESP32 C3 Mini

Please Note: This board requires the CH340G USB driver to be installed on your computer. 

The ESP32 C3 Mini is one of the newest members of the ESP32 chip from Expressif available in a small package for small IOT projects in need of a powerful processor in a system where PCB real estate is a premium.

The ESP32 C3 has 15 gpio’s are available to use with function capability such as I2C, I2S, UART, PWM, making this a highly versatile microcontroller. Wireless communication types such as Bluetooth 5.0 and WiFi come as standard and offer limitless applications.

Like the previous generations of ESP32 microcontrollers,  this one works on the 3.3V logic level. For sensors and any ancillary hardware that functions on the 5V logic level, please use a 3.3-5V logic level converter. The ESP32 C3 can be programmed via the widely used Arduino, platformio or Thonny programming environments.

This microcontroller comes pre-soldered for your prototyping convenience.
