SunFounder (Upgraded) Channel DC 5V Relay Module with Optocoupler Low Level Trigger Expansion Board for Arduino UNO R3 MEGA 2560 1280 DSP ARM PIC AVR STM32 Raspberry Pi

I spent a couple of weekends trying to get one working for the Arduino with no success, This came plugged into to Pi and heyy presto. No fiddling around nothing, works like a dream too.

These have worked perfectly with a rasberry pi to make a garage door controller

I am using these relays to control LED strip lighting. The controller operates on 5VDC and the lights require 12VDC. These relays provide a perfect solution. The optocouplers provide an added level of isolation. The relay coils operate on low current 5VDC. The output contacts can handle high current loads of different voltages. There is a set of NO and NC contacts for each relay. Each relay is operated independently. I recommend this product for anyone that requires isolation between the controlling circuit and the output load.

Toestel is al beschadigd: gebogen en gekrast. Lijkt wel al eens gebruikt geweest.

Todo bien funciona muy bien
