DC-DC Automatic Buck Boost Modul 3-20V bis 3,3V/5V/12V Step Up Down Power Modul
ab 9,47 €
This module is not suitable for inductive loads such as motor relays, speakers, etc. Here is just a solution: it requires parallel TVS tubes or diodes at the output end. Connect a 470UF/25V electrolytic capacitor in parallel at the input of the module (near the module) and connect 100UF or 220UF/25V in parallel at the output of the module.
