Hardware Specifications

Here is a list of the major hardware features:

• 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.
