Banggood

Je n'ai pas encore essayé ces 4 modules, mais ils ont l'air bien réalisé.

Other than the time it took for them to show up, I have zero problem with these circuits. I got them to make a little square wave synth, and they seem to work pretty well for the job

Perfect

buen precio y buen embalaje

Banggood sempre perfetto. Oggetto come da descrizione. Tapporto qualità prezzo ottimo. Grazie.

It does just it's job, big range of duty cycle. It is required a relay 90% of time if you plan to pilot some power circuit.

This board is very basic and can produce a square wave with adjustable duty cyclen and frequency.

El precio es muy bueno. Cinco unidades completas y montadas como se ve en la fotografia del vendedor. Falta probar como funcionan
