Review on 🔑 Keywishbot Mini Nano Board ATmega328P 5V 16M Micro Controller Board – USB Cable Included – Compatible with Arduino Nano V3.0 (Pack of 3) by Justin Smith

I had an idea for one of those silly projects that takes a lot of time and detail to make something that could be solved with a sticker or an Alexa query. I wasn't sure if this little board could handle it all, especially when I added a micro SD. Right now we have a micro SD, a 16 key keyboard, a real time clock and a nice little display. All this with a few pins left over. The keyboard uses most of the pins because the RTC and display use a two-wire bus, and the SD drive uses few extra pins. If I'm talking like a caveman who just opened fire, it's almost true. Almost 30 years have passed since my last project. You kids these days don't know how easy you pulled it off. We used to have to dig our own crystal to make our transistors: DUpdate - Had to remove SD reader. Not Nano's fault, apparently there is a known issue with the SD reader not working well with SPI displays, which doesn't make sense to me since they use different pins, but after a lot of testing and reading I got around to it .
