This page is currently dedicated to a proposal of a Lisa/M to Overo Gumstix breakout board.

10/100 Base-T ethernet phy (at least one if not two)
USB Host
USB OTG
FTDI based USB to serial converter connected to the Overo serial console
Isolated SPI for connectivity to Lisa/M or other systems
Isolated USART for connectivity to Lisa/M or other systems
Levelshifted I2C to 5V/3.3V
Levelshifted Gumstix GPIO to 5V/3.3V
Break out and level-shift GPIO 48,49,50,51. Those pins are the hardware UART TX, RX, CTS, RTS pins. It is very useful to have the CTS and RTS pins broken out, in case someone would want to set up an PPP network link using two Digi XTends. It is not possible to use software flow control in this case, as the binary data stream might contain bytes that equal ctrl+s or ctrl+q.
Break out PWM GPIO pins, e.g. to be able to control servo's. (maybe also level-shift to 5V)
