Reliable and fast
Used this to control a small robot arm over WiFi. The latency is low, and the connection remains stable even when moving around the room. The CH340 chip ensures reliable serial communication.

Great value for money
Bought five of these for a student workshop. All of them worked out of the box. The build quality is surprisingly good for the price point, and the pin headers are pre-soldered which saved us time.

Solid performance, minor heat issue
Works exactly as described. Uploading code via Arduino IDE is seamless. The only reason for 4 stars is that it gets slightly warm during continuous data transmission, but nothing concerning for this form factor.

Good board, documentation could be better
The hardware is fantastic and stable. However, the included paper manual is very basic. You will need to rely on online communities for advanced project ideas. Still, highly recommended for the price.

Perfect for IoT beginners
The Type-C interface is a huge upgrade from the old Micro-USB boards. It connects instantly to my laptop, and the CH340 driver worked without any issues on Windows 11. Great board for learning WiFi protocols.

Type-C makes all the difference
Finally, a development board with a reversible connector! No more fumbling with cables. The signal strength is excellent, and I had no trouble connecting to my home network from across the house.
Q: Does this board support MicroPython?
A: Yes, the ESP8266 V3 board fully supports MicroPython. You can flash the firmware using esptool.py and start coding in Python immediately.
Q: Does it come with pin headers soldered?
A: Yes, this version comes with male pin headers pre-soldered, so it is ready to use with breadboards right out of the package.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: While the ESP8266 runs on 3.3V, we recommend using a dedicated voltage regulator module when connecting a LiPo battery to ensure stable power delivery and prevent damage to the board.
Q: What is the maximum current this board can supply to sensors?
A: The onboard regulator can typically supply up to 600mA, but for stability, we recommend drawing no more than 300mA from the 3.3V pin for external peripherals.
Q: Is the CH340 driver included in macOS?
A: Recent versions of macOS often include the CH340 driver by default. If your system does not recognize the board, you may need to download the latest driver from the manufacturer's website.
