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

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.

. You need to install the CH340 driver. I used the windows driver from the chip manufacturer's website and it worked great. These boards use the old bootloader - if you select the Arduino Nano in Tools, you must also select the ATmega328P (old bootloader) in the processor. Otherwise you will not be able to download programs.

All three Nano Boards worked and I was able to upload sketches on them. I haven't soldered the connectors yet, but wanted to test the boards first. As another reviewer mentioned, getting the driver to work (especially on a Mac) can be tricky, but since I've set it up for a different board before, it wasn't a problem this time. I appreciate that there are no soldered headers on the boards so you can choose how you set them up or just plug them straight into the board. I wish all Arduinos had…
