Typical circuits that can be built on the PB-502 include: Operational amplifiers, comparators, A to D converters, gates, and counters. The PB-502 can also interface directly to a microprocessor. The PB-502 is housed in a tough, molded plastic carrying cases with an integral hinged cover which stacks neatly for storage.

||±12 V @ 200 mA; 5 V @ 250 mA
||Selectable output voltage of clock, pulser, & logic switches. Input voltage thresholds of seven segment displays, logic indicators and Vcc tie-points between 5 V, TTL and 12 volts, CMOS
||Fixed at three levels: 1 Hz, 1 kHz, 100 kHz
||Two fully-debounced pushbuttons with true logic and complementary outputs; Logic "1" output current 2 mA @ 4 V min (5 V/TTL); Logic "1" output current 4 mA @ 11 V min (12 V/CMOS); Logic "0" output current 2 mA @ 0.1 V max (5 V/TTL); Logic "0" output current 5 mA @ 0.1 V max (12 V/CMOS)
||Eight SPDT switches select output of Vcc or ground. Output current, all cases: 200 mA max
||Eight LEDs buffered by two four-bit latches with separate enables. Input impedance, all inputs: 100 kO
||Two BCD-input seven-segment displays with separate Display Enable (DE), Latch Enable (LE), and Lamp Test (LT) inputs.
|Input impedance, all inputs: 100 kO
||All functions are permanently tied to three solderless tie-point connectors. Each tie-point has two solderless connection points. Ground, +5 volts, Vcc, and clock out have four connection points each. All tie point functions are labeled on the front panel.
||Two BNC connectors with the shells tied to ground and the pins connected to adjacent single tie-points
||One UBS-100 solderless breadboarding socket is permanently attached to the unit. The UBS-100 can accomodate up to eight 14-pin DIP ICs with five tie-points per pin plus eight power rails with 25 tie points each
