The ANALOG SHIFT REGISTER is a 3 channel "bucket brigade" style sample and hold circuit that passes each voltage to the next corresponding step when a pulse is received at the clock input. Onboard is a gate to trigger converter with its own dedicated output to trigger other modules within your system.
LED Assembly x 3
This module requires pairs of resistors to be matched. Each highlighted pair of resistors should be matched to each other to give you the best outcome on the output buffers. There are also resistors marked *22k* that should be matched together as well.
3 offset trim pots are provided to zero out the offset of each channel. It is recommended to build and test the module before installing these 3 trimmers. If you notice an offset voltage on each channel then you can go ahead and install these 3 trim pots to zero out each corresponding steps offset.
