DingMai UNO R3 Development Board ATmega328P USB Cable Compatible With Arduino UNO R3

The development board was recognized as an UNO by the Arduino IDE and seems to be working correctly in my project. The price is very attractive considering that the package includes not only the board but also a a USB cable, a protective enclosure, and the useful Phillips #0 screwdriver. Five stars for all that.I deduct one star because I could not use the case when attaching an accessory shield to the development board. The heads of the screws that hold the case together stick up high enough to contact and short-circuit components on the shield. This would not be true for every shield - it depends on the layout of the particular shield. Some shields might work fine with the case. Just be careful.I wish the manufacturer would bevel the screw holes in the lid and use flat-head screws. Then the screw heads would be flush with the case and never interfere with a shield. That improvement would earn this product five stars all the way!

Kept mostly true to original design which is ashame as the voltage regulator wastes so much of the battery power. I would like to have seen a bucking power supply instead of the wasteful regulator. Still, it holds to the original design and functions well.

Worked great out of the box. Recognized as genuine.

Nice boards.

The board is probably ok but it did not come with the case like it advertised.

The DingMai UNO R3 Development Board is a painstaking clone of a genuine Arduino UNO R3 in every way! The board's dimensions and component layout conform exactly to an Arduino-branded UNO R3's, thus making it fully-compatible with any accessory designed for a genuine board. Similarly, the DingMai UNO R3 is equipped with a socketed Atmel ATmega328-PU chip, and exhibits identical functionality and performance characteristics as its counterpart from Arduino.One unique perk of the DingMai UNO R3 kit is that it comes complete with a clear acrylic enclosure! This enclosure allows for better handling of the UNO R3 board when working on projects while simultaneously providing very good overall protection. Unlike enclosures that physically expose the I/O headers above the case's top surface, this case trades-off better accessibility for more comprehensive protection. While this compromise for better protection might prevent some UNO R3 shields from being usable when the microcontroller is installed in the case, such a scenario is typically rare.The DingMai UNO R3 board comes sealed in an ESD-safe bag and boxed with a USB 2.0 Type A-to-Type B cable as well as a screwdriver for assembling the acrylic case. Finally, a "Thank You" card with a dedicated e-mail address for DingMai support is thoughtfully included inside.Priced so good, this kit is definitely an offer you can't refuse!
