Great for IoT projects
Works perfectly with Arduino IDE. The CH340 driver was easy to install and the board connected immediately. Highly recommend for beginners.

Fast shipping and well packaged
No issues with connectivity. The pinout is clearly labeled on the back which saves a lot of time during wiring.

Good value board
Solid performance for the price. Just make sure you download the correct drivers for the CH340 chip if you are on Windows 10.

Solid performance
Gets a bit warm under heavy Wi-Fi load but nothing concerning. Works as expected for home automation sensors.

Perfect for beginners
I was able to upload my first sketch within minutes. The build quality feels sturdy and the USB port is solid.
Q: Is the CH340 driver included?
A: The driver is not on the board itself. You need to download it from our website or the manufacturer's site.
Q: Are the headers pre-soldered?
A: Yes, this version comes with the male headers pre-soldered so it is ready to use out of the box.
Q: What is the max current per pin?
A: Please refer to the ESP8266EX datasheet. Generally, do not exceed 12mA per GPIO pin to ensure longevity.
Q: Does this work with macOS?
A: Yes, this board is compatible with macOS. You may need to install the CH340 driver manually depending on your OS version.
Q: Can I power it with 3.3V directly?
A: We recommend powering via the 5V Micro USB port for stability. Direct 3.3V injection requires careful regulation.
