Arduino-compatible ATtinys with more pins Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate ...

The UDOO contains both and ARM cortex-A9 CPU and the hardware on a Arduino DUE. This includes 54 digital I/O pins, an optional SATA connection, and a number of other pin-outs and connectors.

Not long after [CulinarilySpeaking] got into the Arduino game, he began to want more IO pins and a larger program space for more ambitious projects. This, of course, led him down the path towards t… ...
