Droking PWM Signal Generator 1Hz~150kHz Adjustable Pulse Frequency Duty Ratio Duty Cycle PWM Module 3.3-30V 12V/24V Rectangular Square Wave Generator LCD Display

The product was a replacement. For one project I'm been building. I accidentally blew the transistor inside the PWM Frequency Module. So needed a replacement. If I hadn't been so careless the Module would have been alright. The project is still in prototype stage. I repaired the module that I blew the transistor in. That's part of my other order. Thanks very much. Ron.

Très bon rapport qualité prix

prodotto ricevuto nei tempi previsti, funziona correttamente ed è abbastanza preciso. Occorre però alimentarlo ad almeno 9 volt altrimenti il display non riesce ad offrire una luminosità costante ed adeguata.

perfecto buen producto y facil de usar

Entspricht keinesfalls der Produktbeschreibung. Regelung nur bedingt linear. Ein Gerät für Hobby Bastler

Conforme à mes attentes
