PI CM3+ Compute Module Schematic and PC Design

Create Circuit Boards for Raspberry PI Compute Module 3 Breakout Board for Raspberry Pi CM3+ 2X USB A Ports 1X DSI Input for Display 4X buttons (to trigger GPIO ) 1X Ethernet Port 2X CAN BUS (1 MBIT with MCP2515 based on PICAN DUO Layout) 120 ohm End resistors should be broken out to the main connector to be able to enable / disable via loop on main connector 8X Analog 0-5 V inputs (with overvoltage protection ) 8x Digital 5 - 14 V inputs (overvoltage protection optocupler ?) 1X LDR Sensor (To be able to automatically dimm the display) 1X Real Time Clock incl button battery 1x Speaker 1x Voltage Converter with Shutdown Circuit (10-15 V input ) Stepdown to 5,1V and 3,3 V .(Voltage loss should trigger a GPIO pin so I can switch off the Pi safely by monitoring the PIN )  Switched 12 V input should trigger the Circuit to switch on the CM . There should be a Capacitor which can supply enough power to the PI CM for 20 Seconds in order to trigger a safe shutdown via GPIO Pin , as well as stabilize the Power during cranking of the CAR . 1x WIFI with external Antenna Connection There should be 1 34 Way Connector (Amp Superseal 2-6447232-3) for the following connections 1x Sensor Ground 9 Ground for the Analog inputs 8x Analog inputs 2x CAN High 2x CAN Low 8 x Digital inputs 1x 10-14 V Input 1x Main Ground 1x 3,3 V out 1x Ground out 1X SDA out 1X SDL out 2x Bridgeable pins for CAN 1 120 Ohm resistor 2x Bridgeable pins for CAN 2 120 Ohm resistor Separate PCB’s ( To plug and play for modularity ) 1x GPS Ublox Neo M8N via Serial with external Antenna Connection 6x Adressable RGB led on separate PCB mounted in one row
