Good performance, needs driver setup
Works great once you get the CH340 drivers installed. Just make sure to download them from the manufacturer's site if your OS doesn't recognize it immediately. Otherwise, it's a fantastic little board.

Perfect for beginners and prototyping
This board works flawlessly with the Arduino IDE. The CH340 driver was easy to install on Windows 10, and I had my first LED blinking within minutes. Great value for the price.

Reliable and affordable
I use these for all my home automation prototypes. They are stable, run cool even under load, and the price point allows me to keep several spares on hand.

Excellent replacement board
My old board died, and this was a perfect replacement. The improved version seems to have better soldering quality on the USB port compared to older models I've used.

Solid board, minor pin labeling issue
The functionality is excellent and it uploads code quickly. However, the silk screen labeling on the back is slightly faint. Once you know the pinout, it's not a problem at all.
Q: Is this compatible with Mac OS?
A: Yes, it is compatible with Mac OS. You may need to install the CH340 USB-to-serial driver, which is available for download on our support page.
Q: Can I power this board with a 9V battery?
A: Yes, you can connect a 9V battery to the barrel jack or the Vin pin. The onboard regulator will step it down to the required 5V for the microcontroller.
Q: What is the difference between this and the original version?
A: This V3.0 improved version features an updated CH340 USB interface chip which offers better stability and broader operating system compatibility compared to older FT232-based clones.
Q: Does it support PWM on all digital pins?
A: No, PWM is supported on specific digital pins: 3, 5, 6, 9, 10, and 11. Please refer to the pinout diagram in the product manual for details.
Q: Does this board come with a USB cable?
A: No, this package includes only the development board. A standard Micro-USB cable is required but sold separately.
