This module was an early project to get on my feet concerning workflow and the process of originating micro slot modules. This is a programmable timing module that delivers a digital pulse train at a selectable rate. With a trimmable duty cycle range with VR1, it permits a 5VDC clock output by way of integer multiples. By applying jumper settings at P1, the rate of the pulse stream becomes assigned and fixed until another rate is chosen.
The module uses an 8MHz precision Abracon crystal. The microswitch at SW1 provides for a one-shot pulse for triggering purposes. The modules allow for a standard mounting via the same footprint earlier originated. The module also provides for power presence LED along with a resettable protection fuse at F1.
