Solid performance, runs a bit warm
Using this to control smart lights. It connects quickly to my router and holds the connection well. I noticed it gets slightly warm during continuous transmission, but nothing concerning. Just ensure adequate ventilation in your enclosure.

Good board, documentation could be better
The hardware is solid and the Wi-Fi range is surprisingly good for such a small form factor. However, finding specific pinout diagrams for advanced features took some digging in community forums. Once set up, it runs stable.

Excellent alternative to ESP8266
I needed a cheap Wi-Fi controller for a sensor network and these fit the bill perfectly. The Beken chip is efficient, and the board layout is clean. I've deployed ten of them so far with zero failures.

Great for learning embedded systems
Bought this for my university project. It's affordable enough to make mistakes with but powerful enough to handle complex logic. The minimum system design saves space on my custom PCB prototypes.

Perfect compact board for IoT projects
This little board packs a punch. The built-in serial download module makes flashing firmware incredibly easy without needing an external programmer. It works seamlessly with the Arduino IDE once you add the board manager URL. Great value for the price.

Reliable and fast shipping
The board arrived well-packaged. Uploading code via the onboard USB-TTL is a breeze compared to older boards requiring FTDI adapters. Highly recommend for anyone building low-cost IoT devices.
Q: Can I power this board directly via the USB port?
A: Yes, you can power the board through the micro-USB port. It includes a regulator that handles the 5V input from USB and converts it to the required 3.3V for the chip.
Q: What is the maximum current draw for the 3.3V output pin?
A: The onboard regulator can typically supply up to 200mA, but it is recommended to keep the load under 150mA for stability and to prevent overheating. For higher current needs, use an external power source.
Q: Is this board compatible with the standard Arduino IDE?
A: Yes, it is compatible. You will need to add the specific board manager URL for the Beken BK7231N chips to the Arduino IDE preferences to install the necessary core files.
Q: Does this support Bluetooth connectivity?
A: No, the Ai-Thinker AIR001 with the BK7231N chip supports Wi-Fi only. It does not have Bluetooth capabilities. If you need Bluetooth, please look for models specifically listing BLE support.
Q: Does this board support 5V logic levels on the GPIO pins?
A: No, the GPIO pins operate at 3.3V logic levels. Applying 5V directly to the GPIO pins may damage the microcontroller. Use a level shifter if interfacing with 5V sensors or modules.
