Frequently Asked Questions

Q: What is the ESP32-C3 and what can I build with this development board?

A: The ESP32-C3 is a low-cost, low-power system-on-chip (SoC) featuring a 32-bit RISC-V CPU, integrated 2.4 GHz WiFi, and Bluetooth 5.0 LE. With this development board, you can build a wide range of IoT devices, including smart sensors, wireless data loggers, home automation controllers, BLE beacons, and more. It is fully compatible with the Arduino IDE, MicroPython, and Espressif's ESP-IDF framework.

Q: What is the difference between the "welded" and "not welded" variants?

A: The ESP32 Welded variant comes with GPIO header pins already soldered onto the board, making it plug-and-play with breadboards and standard prototyping setups. The ESP32 Not Welded variant ships without pre-soldered headers, giving advanced users the flexibility to solder their own connectors or mount the board directly onto a custom PCB.

Q: Is this board compatible with Arduino IDE and MicroPython?

A: Yes! The ESP32-C3 development board is compatible with the Arduino IDE (using the ESP32 board package), MicroPython, and Espressif's official ESP-IDF toolchain. Simply install the appropriate board support package and you can start uploading your sketches or scripts right away.

Q: Does this board support both WiFi and Bluetooth simultaneously?

A: Yes, the ESP32-C3 chip supports concurrent 2.4 GHz WiFi (802.11 b/g/n) and Bluetooth 5.0 Low Energy (BLE) operation, enabling you to build connected devices that communicate over both protocols at the same time.
