A&D Board User Manual and Test Procedure

Operation

The circuit diagram of the ANDY board is shown in Appendix A. The silk screen of the board is

shown in Figure 1. The six different sections of the board that are used to connect to the

breadboard are outlined in red: the power sources; the digital logic probes; the digital switches;

the digital pulsers; the digital clock; and the function generator. Each section has labeled socket

headers associated with it. Socket headers are the black boxes surrounding the breadboards into

which wires can be inserted.

The function and operation of each section of the board is discussed in the following paragraphs:

A) Power Sources

These socket headers are labeled “+5V”, “+9V”, and “-9V”. Any of the 4 holes on a socket

header may be used to connect a power source to a circuit on the breadboard.

The ANDY board contains two common ground socket headers: one between the +9V and -

9V socket headers and another between the clock and the function generator socket headers.

The common ground will be used as the reference node for the circuits designed on the

breadboard.
