The "shutdown" daemon
The "carberry" daemon
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.
Logic shutdown signal to Raspberry Pi to perform a controlled shutdown.
Low power consumption compatible whit automotive standards (< 3mA).
Communication to the Raspberry Pi via UART (Pin 15/16 of P1 header).
+12V Ignition signal input.
+12V Ignition signal output with a 2.5A power mosfet.
Two CAN Bus lines for series or parallel connection at vehicle buses.
Two GMLAN lines for series or parallel connection at vehicle buses.
Two channels for resistive steering wheel controls, with single key bypass capability.
One general purpose UART 5V/3V3.
Two general purpose 100mA open collector outputs.
Two general purpose inputs (to ground or 5V tolerant).
Two general purpose user-programmable LEDs.
Microchip PIC32MX microcontroller.
Button and two-color LED for can bus profiles learning and reset functions.
PWM signal to Raspberry Pi for LIRC management.
Infrared remote control emulation for media centers via steering wheel controls.
Infrared sensor for 38KHz IR remote controls.
Infrared LED for IR codes emission.
Ready to Apple MFI program to develop applications under Linux (coprocessor not provided).
RTCC to handle date and time with car battery backup.
Raspberry Pi wakeup by RTCC at programmed date/time.
External EEPROM with a unique identifier to be used for any licenses related to the card.
Accelerometer + magnetometer, for anti-theft features, positioning, blackboxes.
Raspberry Pi wakeup by accelerometer and magnetometer events.
Microusb device connector for a stand-alone operation of the shield or future functionality.
