Easy to setup
Flashed MicroPython within minutes. The USB-C connection is a nice touch for modern setups. Low power consumption seems accurate based on my tests.

Excellent value
Bought five of these for home automation sensors. They all work consistently. The dual-band wireless capability is a huge plus for reliability.

Good but needs patience
Board works well once configured. Had some initial driver issues on Windows 10. Documentation could be more detailed for beginners.

Great board, tiny pins
Performance is excellent for the price. The only downside is the pins are quite close together, so soldering requires a steady hand. Otherwise, works flawlessly with Arduino.

Perfect for compact IoT projects
This SuperMini board is incredibly small yet powerful. Wi-Fi connection is stable and Bluetooth pairing was seamless. Highly recommend for space-constrained builds.
Q: Does it have an external antenna connector?
A: No, this SuperMini version uses a built-in PCB antenna. For external antennas, please check our Pro version.
Q: Can I power this with a LiPo battery?
A: Yes, but ensure you use a separate charging module. The board itself does not have a built-in battery charger circuit.
Q: What is the maximum current per GPIO?
A: Each GPIO pin can source or sink up to 40mA, but total current should be managed to avoid overheating.
Q: Is it compatible with Arduino IDE?
A: Yes, fully compatible. You need to install the ESP32 board manager package within the IDE.
Q: Does this support 5V logic?
A: No, the GPIO pins operate at 3.3V logic levels. Applying 5V directly may damage the board.
