Review on ELEGOO Nano V3.0 Board without USB Cable, CH340/ATmega+328P, Arduino Nano Compatible (Pack of 3) by Ashley Leatham

I really didn't want to buy these because I didn't want to develop designs around them only to find out they were incompatible or unstable or worse I would get a few bad ones. . and spent his time fixing the prototype. But considering the price (less than $4 at the time of writing this review) I couldn't help but try it. Since then I've bought about a dozen and I'm happy to say that they all worked flawlessly no matter what I used them for. I hooked up a bunch of analog sensors to these little boards and used them to control the 2812 problem. Some projects, like the board in the photos, have a lot of code working with multiple photoresistors, wireless communication with LED lights, and self-calibration. Not only is this Arduino-compatible board a good, inexpensive solution, but it allows us hobbyists to build prototypes that can take up a small footprint, which has always been a problem (at least for me). No matter what your projects look like today. and even if this little board doesn't provide enough inputs or outputs for you if you use arduino boards there will be times when a nano board like this will come in handy so go ahead and get it, even if you plan to just keep them in your tool box for now. Personally I have a pair just in case I have an idea and I just need to hook one up to the breadboard to test the sensor or something. Because for me, having an Arduino that I can just plug into a breadboard is priceless.
