I'm glad to show you Carberry Project, an expansion module that allows you to interface RaspberryPi with some car systems.
Carberry aims to be a shield for Raspberry Pi microcomputers.
Carberry represents the link between car electronics and Raspberry Pi, which allows the development of end-user applications, such as media centers, vehicle diagnostics, data logging, fleet management, tracking, blackboxes, burglar alarms, carputing, internet, and much more.
- Same size printed circuit board as of Raspberry Pi, with proper shaping.
- Connection to Raspberry via the P1 26 pin GPIO header located on the board.
- 22 pin Microfit connector for vehicle connection.
- Power supply +12 V and GND from the vehicle.
- Power supply 5V 1A for Rasperry Pi generated onboard by Carberry.
- Control of the Raspberry Pi power supply by mosfet, for the management of low consumption.
