We’ve had the Arduino based on Atmel’s ATMEGA8 and ATMEGA168 ‘AVR’ microcontrollers for some time. More recently, the Raspberry Pi (ARM ARM1176JZF-S on a Broadcom SoC) has stormed onto the scene along with the Gertboard (PIC + A/D + D/A + buffering) add-on for “general purpose I/O”. Also, there is now the IOIO board (PIC24F):
External I/O board for Android devices:
Developer Ytai Ben-Tsvi has announced a new model of the IOIO board, which can be used to add measurement and control inputs and outputs to Android smartphones and tablets…
USB-on-the-go (OTG) is available, which means that the new model allows configuration of the operating mode it should use – it can register itself as a host on a smartphone or as a device on a PC…
Enough choice there to make any I/O pin go wobbly! 🙂
Enjoy,
Martin
