Review on 🔧 Longruner for ArduinoIDE Mini V3.0 ATmega328P 5V 16M Micro Controller Board Module for ArduinoIDE - Set of 3 by Joe Gosa

They are reasonably priced and very reliable. I've used many of these over the past few months and they've all worked flawlessly. I hooked up a bunch of analog sensors to these little boards and used them to drive 2812 LED strips with no problems. Some projects, like the board in the photos, have a lot of code working with multiple photoresistors, wireless communication with LED Luminaires 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're using Arduino boards, there will come a time when a nano board like this will come in handy, so get one, too if you plan to just keep them in your toolbox for now. Personally, I keep a few in case I have an idea and just need to hook one up to a breadboard to test a sensor or something. Because for me, having an Arduino that I can just plug into a breadboard is priceless.
