Another great deal!This micro-controller has more I/O pins and PWM outputs than the ATtiny85 and adds serial support, however it does not support ADC and has smaller flash and RAM capacity. A good choice for projects that are not overly complicated but require heaver input or output capabilities.
Good MicroprocessorI bought a few of these for small projects. Other than the small 2k of program space, which is more than enough for simple applications, this is a great chip. No external crystal needed for 1MHz or 8MHz mode. If you have an Arduino, use the Arduino as ISP and find the cores for the attiny series, and you'll be ready to go.
Note that there is no analog to digital converter on these chips, but there is PWM. Almost a better idea to pay $1.50 more to get an ATMega328 with much more features.
