CaR board v2.0

• Still working on the test-board
• Mostly finihsed with the schematics
• No estimate for the layout

Follow-up on Carboard v1.4 from DESY with broken connector repaired at CERN (Tomas, Eric)

• Connector repair was successful, but board had issue with powering afterwards
• Found a broken line under an AND gate on the board. Fixed by placing additional wire. 
• Damage to line could have happened during repair (heating up of the PCB), but difficult to be sure about it
• Similar issue was once seen on a Carboard in the testbeam at CERN, which suddenly failed. Should try to find it back and see if it has the same cause.
