Excellent Quick Tech Reference..
Found this app to be an excellent reference for my hardware projects. Clean, simple, with lots of spec info for simple circuits. Would like to see more pin layouts for more boards but great resource as it is now.
Just what I needed
I mainly got this for the resistor codes but I have no doubt I'll put the other tools to use too. It's a nice little app and I'm happy to support Adafruit software!
Much more convenient than searching the Internet and handy when checking all kinds of things like USB connector pinouts.
With Family Sharing set up, up to six family members can use this app.
