Review on 5Pcs Longruner Arduino Mini Nano V3.0 ATmega328P Micro Controller Board Module With USB Cable For ArduinoIDE by Jason Masango

They work great, once you install a boot loader. It is really annoying for me to do though, because I didn't want to install the pin headers that you need to do it for my project. Plus, I think it would be required to state in the description that another, working Arduino board is required to make these work. The only other working Arduino that I had was installed in another project, so I had to take it all apart and use it, then reinstall it and reflash it. I was able to do it, but I wish that I didn't have to take that step at all.
