Revision as of 05:48, 31 August 2012
This page is currently dedicated to a proposal of a Lisa/M to Overo Gumstix breakout board.
System Design
Wishlist
- 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
