Preface: I'm not an engineer, pls have patience.
I would like to get a Propeller Project Board and have it connect to 7 Ping Ultrasonic sensors, 11 Ping Laser Rangefinder sensors and have two connections to a Dual H-Bridge Motor Controller. I might also connect it to a voltage sensor. I will need many 3 pin connectors in the prototype area. I suppose I will need a 5V regulator for all these connections.
I wish Parallax or someone would make a breakout board for the Propeller that accepted 3 Pin wires for each IO. That would be cool.
