Review on 🔌 Emakefun Nano V3.0 ATmega328P 5V 16M Micro-Controller Board with USB Cable - Soldered 5pcs by Brandon Miller

I use a lot of nano in my projects, so I know a bit about this topic. I ordered 10 (2 sets of 5) from this seller and received them quickly (as expected from Revain). The first set of 5 programs with no problems, but the second set doesn't accept the program over the USB port (using the Arduino IDE). I returned and received another set of 5 which basically had the same problem but this time I had a little more time to work with them and I broke my old AVR programming board and figured out how to get the bootloader -Could install code on it. It worked and the Nano could now be programmed as usual. If you understand what I'm talking about and you have a programmer then order it knowing that you may or may not need to program the bootloader. If you're a little confused about this, don't have a programmer, or just don't want to waste time - RUN!
