Best board for university projects
Bought this for my final year project. It handles complex sensor data logging and cloud uploading without breaking a sweat. Highly recommend for students.

Seamless MicroPython support
Flashing MicroPython was straightforward. The REPL works smoothly over the USB serial connection. A fantastic tool for rapid prototyping.

Compact and powerful
The form factor is tiny which fits perfectly into my custom enclosure. Only giving 4 stars because the header pins were not pre-soldered, but that's expected for this type of module.

Great value, minor documentation gaps
Hardware is solid and the RISC-V architecture performs well for the price. I wish the pinout diagram on the back was slightly larger, but the online docs compensated for it.

Reliable Wi-Fi and BLE
I've been testing this for a home automation sensor node. The connection stability is impressive, and the low-power modes work exactly as specified in the datasheet.

Perfect for IoT beginners
The dual Type-C ports make powering and programming incredibly convenient. The board was recognized immediately by my computer, and I had my first LED blinking in minutes using the Arduino IDE.
Q: Does the dual Type-C mean I can use one for power and one for data simultaneously?
A: Both ports are connected to the same USB-to-UART bridge and power rail. They function redundantly, meaning you can use either port for power and programming, but they do not offer separate independent channels for simultaneous distinct tasks.
Q: Can I power this board directly via the Type-C port from a phone charger?
A: Yes, you can power the board using any standard 5V USB Type-C charger or computer USB port. The onboard regulator handles the conversion to 3.3V safely.
Q: Does this board come with header pins pre-soldered?
A: No, the board is shipped without header pins soldered to allow for flexible mounting options. You will need to solder them yourself if required for your project.
Q: Is this compatible with the original ESP32 libraries in Arduino IDE?
A: Most libraries are compatible, but you must select the 'ESP32C3 Dev Module' board manager in the Arduino IDE settings to ensure the correct compiler flags are used for the RISC-V core.
Q: What is the maximum current draw for the GPIO pins?
A: Each GPIO pin can source or sink up to 40mA. However, the total current for all IO ports combined should not exceed specific limits outlined in the technical reference manual to prevent damage.
