Relays & Relay boards
Het omzetten van een kleine elektrische input in een hoogvermogen output is geen sinecure, maar deze taak is noodzakelijk om een breed scala aan standaardapparaten en voertuigen efficiënt te laten werken. Veel circuits bereiken deze conversies door het gebruik van relais, die onmisbaar zijn in allerlei elektronische apparatuur.
Bits & Parts heeft relais en relaisboards voor alle toepassingen. De meeste relais zijn aan te sturen vanuit een microcontroller zoals een ESP32, Arduino en Raspberry Pi.
