Review: Simple latch, multiple input options to trigger, works well. - I like the separate set/reset inputs along with the pulsing input or toggle. It works well and seems well built and simple. Through-hole design can be repaired by the hobbyist.
Review: Great product & value - Although the product ships without documentation, it's easy to download and print what you need. Very versatile board, and it does exactly what it says it will do. As a bonus, the terminals are big enough to squeeze two 16AWG wires into!
