This module is made of two SR type latches. Each has a Set input which turns the output on and Reset input that turns the output off. Gates, triggers, square or saw waves can be used as inputs The outputs are +5V gate signals.
The PCB uses PC mounted jacks so there is no wiring when building for Eurorack. The PCB has mounting holes so offboard jacks can be used for building in other formats.
For complete descriptions of the way the module is used, and how to build it, including schematics and parts list; download this PDF file.
Boards are available now. Price for 1 PCB is $8.
Unfinished eurorack
panels are available for this project, they are 4HP and cost $7 each.
There is
