For instance, it's not full duplex, so sending and receiving at the same time will produce gibberish. This works quite well but you do need to know its limitations. There is a custom library built in to the ATTiny Core called "Serial" which is actually an implementation of Software Serial. The ATtiny doesn't have a hardware UART, so serial doesn't work the way you might expect. Powering your project through the USB connector is a good, too. There is no power regulator on the Atto84, so the input to VCC must be between 3.3V and 5V. Sounds great, right? It is, but there are a few catches that you should be aware of. Yeah, why not? The tiny84 has plenty of timers and you'll find a copy of the Servo library included with the core! The "Gotchas" The ATtiny actually has hardware SPI support, so the Atto84 will work identically to the Uno in that respect. This means that it will run any Wire-based code that you've written for ATmega platforms like the Arduino Uno or the SparkFun RedBoard. The ATTiny Core includes a special version of the Wire library that leverages the tiny84's hardware USI for I☬ communication.
