Review on 🔌 HiLetgo 3pcs Nano V3.0 ATmega328P CH340G 5V 16M Mini USB Micro Controller Board with Headers (Unsoldered Pins) - Development Board by Miguel Yurco

Must put in some product prototypes and will work great. Because they're so cheap, I don't have to think twice about never seeing them again. All 3 of my boards powered up when plugged in and were able to accept the standard Arduino blink sketch, so everything is fine. Only the small quartz oscillator next to the main chip seems a bit carelessly attached. I put a drop of epoxy on each of them to keep them from cracking and now everything looks fine.
