Perfect ESP8266 Upgrade
Much more stable Wi-Fi connection than my old boards. The Bluetooth LE support is a nice bonus for my home automation setup.

Excellent for IoT Prototyping
Works straight out of the box with Arduino IDE. The RISC-V architecture is fast enough for my sensor logs and Wi-Fi connectivity is stable.

Low Power Mode Works
Verified deep sleep currents are as specified. Great for battery projects where energy efficiency is critical.

Documentation Needs Work
Board is fine and functions correctly, but finding specific pinout diagrams took some digging compared to other brands.

Good Value Board
Solid performance for the price. Wish it had a built-in battery connector though, but otherwise meets expectations for development.
Q: What is the maximum current per GPIO pin?
A: Please refer to the official datasheet, but generally do not exceed 40mA per pin to ensure safety.
Q: Is the USB cable included in the package?
A: No, the board is sold without a USB cable. You will need a standard USB Type-C cable for power and programming.
Q: Does it support Bluetooth Classic or only BLE?
A: The ESP32-C3 supports Bluetooth 5 Low Energy (BLE) only, not Bluetooth Classic.
Q: Does this support MicroPython firmware?
A: Yes, the ESP32-C3 is fully compatible with MicroPython and CircuitPython frameworks.
Q: Can I power this with 3.3V directly on the VIN pin?
A: No, please use the 5V pin or USB for input. The 3.3V pin is an output unless specified otherwise in advanced guides.
