Product Description

The ESP32-C3 brings the reliability of the ESP32 family to a smaller, more affordable package. It features an integrated USB-to-Serial converter, allowing for seamless programming via the USB Type-C port. With its high-grade RF performance and low power consumption (as low as 43µA in deep sleep), it is an ideal choice for battery-operated sensor nodes, smart home automation, and wearable technology.

Key Features

  • RISC-V Architecture: Utilizes the open-standard RISC-V core for efficient processing and a streamlined development toolchain.

  • Dual Wireless Connectivity: Supports both Wi-Fi for cloud connection and Bluetooth 5.0 LE for local smartphone interaction and mesh networking.

  • Pre-Soldered Headers: Saves time and ensures reliable electrical connections right out of the box.

  • Compact Form Factor: Often referred to as a "Super Mini" board, it is significantly smaller than standard ESP32 DevKits, fitting easily into tight enclosures.

  • Broad Software Support: Fully compatible with the Arduino IDE, ESP-IDF, MicroPython, and CircuitPython.

Technical Details

  • Dimensions: Approximately 22.5mm x 18mm.

  • Onboard LED: Programmable status LED (typically on GPIO8).

  • Buttons: Integrated Reset (RST) and Boot buttons for easy firmware flashing.

Prototyping and Engineering Tips from Robogears

  • 3.3V Logic Level: Like other ESP chips, the GPIOs are not 5V tolerant. Always use a level shifter when interfacing with 5V components to prevent hardware damage.

  • Bootloader Mode: If your computer fails to detect the board during an upload, hold the BOOT button, press and release RESET, and then release the BOOT button to manually enter download mode.

  • Antenna Considerations: These boards usually feature an onboard ceramic or PCB antenna. For projects requiring long-range Wi-Fi, ensure the antenna side of the board is not shielded by metal or thick plastic.

  • Powering via VIN: You can power the board using a stable 5V source on the VIN pin. However, avoid using the USB-C port and the VIN pin simultaneously unless your specific board version includes protection circuitry.

Package Includes

  • 1 x ESP32-C3 Development Board with Soldered Headers

Disclaimer

Ensure you select the correct board definition (e.g., "ESP32C3 Dev Module") in your IDE to ensure the pin mapping and flash settings are correct.
