Category: Development Boards

This development board is based on the common Arduino Uno R3 reference design. It is identical in specification other than it makes use of the ubiquitous CH340 USB interface IC to reduce production cost and therefore allow this board to be sold at a fraction of the cost of the standard Uno without sacrificing any of the Unos functionality. It will run any sketch designed of an Arduino Uno without requiring any modification.

Additionally, this Uno development board also includes the option of being able to add additional pins for the standard Arduino headers, I2C and power pins.

Joseph ★★★★★

The CH340 chip worked flawlessly right out of the box—no driver headaches on Windows 10. Pin layout matches the classic Uno perfectly, so all my shields just clicked on without any modification. For the price, it's a no-brainer for prototyping.

Sofia V. ★★★★★

Plugged it in and the CH340 driver was recognized immediately on Windows 10, no manual install needed. The board feels solid and the pin layout is a perfect match for my existing shields.

Benjamin ★★★★★

Plugged it in and the CH340 driver installed without a hitch on Windows 11, which saved me a lot of headache. Uploaded a simple blink sketch and it compiled and ran perfectly on the first try.
