A Overview The Digilent myProto accessory board for NI myDAQ attaches directly to the myDAQ and brings all myDAQ signals to breadboard connections where they can be easily accessed using simple jumper wires. The myProto also includes several additional useful I/O devices. Signal names on the myProto breadboards indicate which myDAQ signals and onboard devices are attached to which breadboard pins. All Ground connections on the myProto breadboards are connected into a single Ground node on the myProto device. Solderless Breadboard All myDAQ signals accessible from breadboards 3 onboard user LEDs 1 10K Potentiometer 2 Audio Jacks External power connector for breadboard circuits Switches on all power supplies The Digilent myProto board.
