ESP32-C3 WiFi and Bluetooth LE Development Board

ESP32-C3 development board for wireless projects

This ESP32-C3-based board combines a single-core 32-bit RISC-V processor with 2.4GHz WiFi and Bluetooth Low Energy. It offers a platform for compatible sensor interfaces, wireless controls and connected electronics projects.

The ESP32-C3 chip supports 802.11 b/g/n WiFi and Bluetooth LE. Bluetooth Classic audio support is not established; do not choose this board on the assumption that it works as a conventional Bluetooth audio receiver.

Choose the correct board configuration

The exact board revision, module marking, flash capacity, USB circuitry and exposed pin count need confirmation. This listing does not establish that the supplied board is an official Espressif ESP32-C3-DevKitM-1 or uses a particular MINI module.

Use a matching board profile and pinout in your development environment. Arduino-ESP32 and ESP-IDF can support ESP32-C3 development with the appropriate installation and settings. MicroPython use requires a compatible firmware build and confirmation of the board’s hardware.

Power and peripheral connections

ESP32-C3 GPIO uses 3.3V logic. A board’s USB or VIN power connection is not permission to apply 5V to its GPIO pins. Confirm the actual power-input arrangement before connecting an external supply.

Check which UART, SPI, I2C, PWM and ADC signals are available on the supplied board. Chip capabilities do not mean that every signal is accessible on every development-board layout. Verify pin assignments, boot-related pins and peripheral voltage levels before wiring.

Frequently asked questions

Does it connect to 5GHz WiFi?

The ESP32-C3 uses 2.4GHz WiFi, not 5GHz.

Is the flash capacity confirmed?

No specific flash capacity is verified for the supplied board. Confirm the marking and revision before selecting firmware.

Is it the same as an Arduino UNO R3?

No. Processor architecture, pinout and voltage requirements differ; software and wiring must match this board.
