Interconnect Board

At the heart of the robot is the Pi.  But how does it connect to everything else?  Via the interconnect board of course 🙂

This little board is where *everything* connects – where all the sensors, motor drivers, power supplies, Pi, Propeller, etc come together.  Its a very custom board for every robot, so I generally make it by hand using “padboard”.  This is a cheap, 0.1 inch pitch board with drilled pads.  Unlike stripboard, it doesn’t have defined tracks – so you make your own with solder bridges.

This allows a more compact layout than stripboard, while still being fairly quick/easy to use.

Our board has headers on it for logic power supply (in the middle), motor drivers (6 pins, near the edges), sonar pingers (blue) and servos (yellow).
