Reliable for prototyping
I use these for rapid prototyping before moving to custom PCBs. The pin layout is standard, and the build quality feels sturdy. No issues with voltage regulation or connectivity so far.

Good value bulk pack
Ordered 50 units for our workshop. 49 worked immediately; one had a slightly loose USB port but still functioned. For the wholesale price, this is an acceptable trade-off. Will order again.

Exceeded expectations
Was skeptical about the 'improved version' claim, but the board performs identically to the more expensive branded versions I've used. The CH340 chip is reliable and supports high-speed uploads.

Solid board, minor driver hiccup
The hardware quality is excellent and matches the original specs. I had a small issue finding the correct CH340 driver for my older Mac, but once installed, it uploaded code without errors. Highly recommend for learning.

Great for university projects
Needed several boards for my final year project. These worked perfectly with all the sensors and modules I connected. The documentation online is plentiful since it's fully compatible with Arduino standards.

Perfect for beginners and bulk projects
Bought a batch of these for my robotics club. The CH340 driver works flawlessly on Windows 10 and 11 after a quick install. All boards were tested and working right out of the box. Great value for the price.

A: Yes, the CH340 driver is compatible with macOS Catalina and newer versions. You may need to allow the extension in your Security & Privacy settings upon first installation.
Q: Does this board come with a USB cable included?
A: No, this listing is for the development board only. A standard USB Type-A to Type-B cable is required and sold separately.
Q: Can I power this board with a 9V battery?
A: Yes, you can power the board via the barrel jack or the Vin pin using a 7-12V DC power supply, such as a 9V battery. The onboard regulator will step it down to 5V.
Q: What is the warranty period for bulk orders?
