ESP32-C3-DevKitM-1 This user guide will help you get started with ESP32-C3-DevKitM-1 and will also provide more in-depth information. ESP32-C3-DevKitM-1 is an entry-level development board based on ESP32-C3-MINI-1, a module named for its small size. This board integrates complete Wi-Fi and Bluetooth LE functions. Most of the I/O pins on the ESP32-C3-MINI-1 module are broken out to the pin headers on both sides of this board for easy interfacing.

Key Component Description is ESP32-C3FN4, a chip that has an embedded flash of 4 MB. Since flash is packaged in the ESP32-C3FN4 chip, rather than integrated into the module, ESP32-C3-MINI-1 has a smaller package size. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V output. 5 V Power On LED Turns on when the USB power is connected to the board. Pin Headers All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board.
