Frequently Asked Questions

How do I program the DFRobot Beetle ESP32-C3?

You can program the board using the Arduino IDE with the ESP32 board package installed, Espressif's official ESP-IDF framework for full control, or MicroPython for Python-based scripting. Connect via the onboard USB Type-C port, select the correct board (e.g., ESP32-C3 DevModule), and upload your code. Ensure you have the latest USB drivers if needed.

Can I power this board with a battery?

Yes, the board features an integrated lithium battery charging circuit. You can directly connect a 3.7V Li-ion or LiPo cell to the designated battery pins. The onboard charger manages safe charging up to 400mA when USB power is present, and the system operates from the battery's power when USB is disconnected.

What is the purpose of the included expansion board?

The expansion board provides easier access to power pins (5V, 3.3V, GND) and includes a GDI (General Display Interface) connector, simplifying wiring for displays like TFT screens. It makes prototyping cleaner and more convenient without soldering directly to the small main board's pins.

Does this board support Bluetooth Mesh networking?

Yes, the Beetle ESP32-C3 supports both Bluetooth 5 (LE) and the Bluetooth Mesh protocol, allowing you to create large-scale, reliable networks of devices. It also supports Espressif's proprietary Wi-Fi Mesh, giving you flexible options for extending wireless coverage in IoT deployments.
