Great for beginners
This board works perfectly with the Arduino IDE. I used it for a school project and had no issues uploading sketches.

Good value but needs driver
The board itself is fine, but make sure you install the CH340 driver before connecting. Once done, it works well.

Compact and reliable
I bought five of these for my home automation sensors. They are small and fit easily into tight spaces.

Headers not included
I didn't realize the pin headers were not soldered. I had to buy a soldering iron separately. Board works though.
Q: Can I power this with 9V battery?
A: Yes, you can connect a 9V battery to the VIN and GND pins.
Q: Do the pin headers come soldered?
A: No, this version typically comes without headers soldered to allow for flexible mounting options.
Q: Does it support 3.3V logic?
A: The board operates at 5V logic, but there is a 3.3V output pin available for powering sensors.
Q: Is this compatible with Mac OS?
A: Yes, it is compatible. You will need to install the CH340 USB driver for macOS.
Q: Which software do I use to program this?
A: You can use the standard Arduino IDE available for free on the Arduino website.
