Perfect for IoT Prototyping
This board works straight out of the box. The OLED display is crisp enough for status messages and the Wi-Fi connection is stable. Highly recommend for beginners.

Decent but display is dim
The functionality is fine, but the OLED brightness is hard to adjust and seems dim in bright rooms. Good for indoor low-light projects only.

Excellent Support
Had issues with drivers initially but the support team helped me resolve it quickly. The board itself is very reliable for home automation tasks.

Compact Powerhouse
Love the built-in screen. It saves so much space compared to wiring an external display. Bluetooth pairing was quick and easy.

Good value but pinout tricky
Great board for the price. The only downside is that the pinout labels are a bit small. Once you map them out, it works perfectly with Arduino IDE.
Q: What is the maximum input voltage?
A: You can power it via 5V through the USB Type-C port. The GPIO pins operate at 3.3V logic level.
Q: Can I use MicroPython on this device?
A: Yes, MicroPython is supported. You can flash the firmware using esptool or the web installer.
Q: Is this board compatible with the Arduino IDE?
A: Yes, this ESP32-C3 board is fully compatible with the Arduino IDE. You will need to install the ESP32 board manager package.
Q: What is the approximate Wi-Fi range?
A: In open space, you can expect around 50 meters. Indoor range varies depending on walls and interference.
Q: Does it support deep sleep mode?
A: Yes, the ESP32-C3 supports multiple power saving modes including deep sleep to extend battery life.
