Overall an excellent timer circuit. You should plan to spend a bit of time experimenting with it. The instructions are really poorly written in my opinion and the various functions are not well defined. I wound up writing my own instructions with a very specific sequence of actions in case I ever have to replace or reset the circuit in my build. Also, it does have a mild amperage draw so be careful if you wire it in DC parallel with the power to the timed device (consider its own adapter/dc current if the circuit cuts out when your timed device activates). Attached photo showing DC power in on the left and wired to trigger normally open circuit on the right. The small keypad manually triggers.

Set-up Instructions are undecipherable. It appears many modes of operation are possible, but cannot set up this device. Ordered 2 units. Tried 2nd unit thinking perhaps I had a bad part, and minutes after power up of that one, a short developed (noticed another reviewer had a problem with overheating, so this may indicate a quality problem.)

East to setup and use, only one this wrong, the timer needs about 2sec to restart after a re-trigger, not good if you need it to restart right-a-way, The first trigger is fast, but if trigger signal is dropped and immediate returned it needs a 2 sec time to reset. (Installed in a Experimental aircraft for a backup fuel pump system with time delay)

It is a nice board with a Timer programmable to the cycle time, Open Time, Cose Time and repetitions to the cycle. it saves internally your program, so if it goes without battery for a long time, still works the same program on the next power up. I love it. i made hundreds of projects with it.

Very easy to use. Easy to read and Informative display. Wide range DC-input. Can be powered via micro-USB either pernanently or during setup for convinience. Trigger signals can be low- or high-level. Resonable price.
