- | The board consists of a grid of 21 by 30 plated through holes on 0.1" centers which can be used to solder test circuits. Three of the columns of holes on the left side of the grid are shorted together and tied to the +5V, -5V and ground connections on the 30 pin right angle female connector that mates with Discovery. Three of the columns of holes on the right side of the grid are shorted together and tied to the +9V, -9V and ground connections for use with external batteries or other sources of power.

The 21 X 30 grid is sized to accommodate the popular 30 position (400 total connection points) solder-less breadboards with power busses along both sides which are 2 1/8" by 3 1/4". These breadboards come with adhesive backs that will stick the breadboard to the adapter PC board. | The 21 X 30 grid is sized to accommodate the popular 30 position (400 total connection points) solder-less breadboards with power busses along both sides which are 2 1/8" by 3 1/4".

- | The layout of the resistors around the dual op-amp are arranged such that rather than two independent amplifiers, a single resistor can be inserted between the two inverting inputs, in place of the two resistors (R1,R4) to ground. Configured this way the two op-amps form the input section of an instrumentation amplifier. The amplified differential signal at the outputs of the two amplifiers can then be connected to the differential scope inputs on Discovery. Another possible use would be to generate complementary or differential signals from one of the AWGs. By connecting one input to ground, with the other input connected to one of the AWG outputs and adjusting the resistor values the first amplifier acts as a non-inverting stage to generate the in phase or true output and the other amplifier acts as an inverting stage to generate the 180º phase or complement output. To make it easy to swap resistor values individual pin sockets could be installed rather than directly soldering the resistors to the board. Likewise using a socket for the op-amp would allow you to interchange different devices optimized for the intended application. | + | The layout of the resistors around the dual op-amp are arranged such that rather than two independent amplifiers, a single resistor can be inserted between the two inverting inputs, in place of the two resistors (R1,R4) to ground.
