Simple Optoisolator Board Assembly – Step-By-Step Guide

What do you need?

• Breadboard or proto board
• Generic Optoisolator, I’ve used an 4N35
• A Led
• A resistor
• Some wires
• Shrink tubes
• Soldering Iron and solder
• Tweezers and pliers

Once you’ve all the needed parts you have to assembly the board and connect everything together.

Here you’ve the scheme of the connection that I’ve made:

And this is how it looks like after it’s finished and protected with some shrink tube:

The pinout of the circuit is the following:

• WHITE: +12V
• BLUE: Opto Led Cathode
• BLACK: GND
• GREEN: Z-Endstop pin

Plan B: Buy a premade one

For a better result and a flawless installation I’ve also developed a pcb that is currently in production.
