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. Developers can either connect peripherals with jumper wires or mount ESP32-C3-DevKitM-1 on a breadboard.

ESP32-C3-DevKitM-1 Development Board

Key ComponentDescription
ESP32-C3-MINI-1ESP32-C3-MINI-1 is a general-purpose Wi-Fi and Bluetooth LE combo module that comes with a PCB antenna. At the core of this module 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 LDOPower regulator that converts a 5 V supply into a 3.3 V output.
5 V Power On LEDTurns on when the USB power is connected to the board.
I/O ConnectorAll available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board.
Boot ButtonDownload button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port.
Micro-USB PortUSB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-C3FN4 chip.
Reset ButtonPress this button to restart the system.
USB to UART BridgeSingle USB-to-UART bridge chip provides transfer rates up to 3 Mbps.
RGB LEDAddressable RGB LED (WS2812), driven by GPIO8.
