An USB-to-Serial (I2C/SPI/GPIO) bridge.
This is a free USB to serial bridge, based on the Atmel AT90USB647 chip. Hardware and Software are released under an Open Source licence. It supports the following interfaces:
* USB interface (serial emulation)
* I2C (TWI)
* 8 General purpose digital I/O
The board communicates with the host computer using a CDC (USB communications device class). This makes it easy to use userial without installing a device driver or special libraries. Due to the ASCII based command interface it is easy to control devices manually with simple terminal emulation.
