Roostick
Todbot has a review of the RooStick, a USB to serial device for controlling a Roomba – “The RooStick is a USB-to-Serial adapter with a Mini DIN 7-pin socket on it that matches the SCI connector on the Roomba. It is an unencased circuit board with a USB connector soldered on one end and the Mini DIN on the other. The circuit consists of a CP2103 USB-to-UART chip and a couple of LEDs.”Link.
