MakerFocus Mini Nano V3.0 ATmega328P Microcontroller Board w/USB Cable For Ar duino

the board comes as expected with the CH340 chip and works as intended, it is an incredible microcontroller board that packs a lot of power into a small and affordable package. Versatile, easy to use, and perfect for many projects, from robotics and automation to IoT and home automation. Overall, I highly recommend this product to anyone looking for a reliable and versatile microcontroller board.

I ordered two of these, one from each of two suppliers, in China and Hong Kong. 2nd to arrive had better soldering quality. Both seem to function well for the tests I did. Both use the CH340 chip for USB to TTL which seems to load a sketch faster than the TDI232. On the humorous side, the 1st was identified as "watch tools" for customs, which seems to be a common practice with other small electronic parts I've ordered. It's less costly than putting together a functioning microcontroller with a chip & associated parts(which was my second choice) so if it works, to me it's worth a rating of 5.

I did most of my prototyping for a project on a recently purchased name brand Arduino Nano, but I wanted to buy a less expensive controller for the final project due to its physical location and potential to be damaged or stolen. This is the first non-name brand board I've used and had no issues with it. It is important to note that this board uses the old bootloader, so my first few attempts to write the project failed with a slightly unclear communication error from the IDE before the lightbulb went off in my head and I realized the bootloader needed to be switched (my name brand board uses the new bootloader). After that trivial stumbling block, I've had absolutely no issues with this board and will likely buy another for a future project.

Working well

All items in the order arrived in goos time, well packaged and all with their own cable too. All work as well.

Good
