Vraiment un petit circuit avec toutes les possibilités du NE555. Pas la peine de perdre du temps à en câbler un sur une plaquette proto ... De toute façon ça vous reviendra plus cher que ce petit module !

in testing this unit, all the frequency ranges function. The higher 3 ranges have very little ringing and produce a good square wave. On the lowest range it produces more of a saw tooth then a square wave. So some filtering would be needed to run it in the lowest speed if your project needs a clean square wave. Will have to do some additional testing on the adjustments, but on initial test there is a few gaps in the ranges, but that may just be my testing.
