Great features, runs hot

Functionality is top-notch for the price point. Just note that it can get a bit warm during heavy Wi-Fi transmission, so ensure adequate ventilation in your project case.

Good board, minor driver issue

The hardware is solid and compact. I had to install a specific CH340 driver on my Windows machine to get it recognized, but once that was done, uploading sketches was smooth.

Best budget ESP board

Compared to other development boards, this offers the best balance of cost and performance. The pin layout is standard enough to use most Arduino shields with minor adjustments.

5 FAQ

Q: Does this come with a USB cable included?

A: Yes, the package includes a standard Micro USB cable for both power supply and data programming.

Q: Can I power this board with a 5V battery pack?

A: Absolutely. You can power the board via the Micro USB port or the VIN pin using a 5V source. The onboard regulator handles the conversion to 3.3V safely.

Q: Is this board compatible with the standard Arduino IDE?

A: Yes, this board is fully compatible with the Arduino IDE. You will need to add the ESP8266 board manager URL to your preferences to install the necessary core files.

Q: What is the maximum current output for the 3.3V pin?

A: The onboard regulator can typically supply up to 600mA, but we recommend drawing no more than 250mA from the 3.3V pin to ensure stability during Wi-Fi transmission spikes.

Q: How do I put the board into flashing mode?

A: Usually, the board enters flashing mode automatically when you initiate an upload from the IDE. If not, try holding the FLASH button while pressing the RESET button, then release RESET first.
