● Block digram of all model Block digram of all model i.e. A,A+,B,B+ is shown in i.e. A,A+,B,B+ is shown in figure.figure.

● As we can plug raspberry As we can plug raspberry pi into monitor, I/O is done pi into monitor, I/O is done through standard keyboard , through standard keyboard , mouse & Monitormouse & Monitor

● In model A & A+ lowest two In model A & A+ lowest two blocks are absent so usb port blocks are absent so usb port is directly connect to SoCis directly connect to SoC
