Opto Isolator v1.0 – The Best Signal Passing Tool

Do you having trouble to pass the signals in between two circuits and you’re looking to overcome this matter? Stop right here, as you have find the permanent solution for the above problem.

All you need here is a good Opto Isolator v1.0. This little fellow allows you to pass signals from circuit A to B instantly without having to connect them electrically. This is great for wiping out noise problem, and even connects the circuits that have different voltages.

Before that, you have to standby the following components first:

  • Opto Isolator v1.0 PCB
  • Four 100 nF ceramic capacitors
  • Four 220 ohm resistors (R1-R4)
  • Four 3.3K ohm resistors (R5-R8)
  • Two HCPL2631 (IC1 and IC2)
  • One 16 pin DIP socket
  • Two 6 pin IDC header
  • Two 6 pin IDC connector
  • Twelve 10 pin ribbon cable

OK, Let’s begins the soldering mission here…

The complete soldering step-by-step guide:

  1. Socket – The socket will use to hold both chips.
  2. 220 Ohm resistors – Place the four resistors at the “IN” part on PCB. Fold the wire over close to the body and insert it into the PCB. You have to ensure the resistors’ wire faces the chip.
  3. 3.3K Ohm resistors – Place the another four resistors at the “OUT” part on PCB. Also, you have to make sure that the resistors’ wire faces the chip socket as well.
  4. C1-C4 – You can insert the ceramic capacitors in any direction you want.
  5. IDC Headers – Place the headers and solder them up. Double-check and ensure that you put the notches facing inwards, which it will line up with the silkscreen.
  6. Chips – Insert the two chips. One at the very top, while another at the very bottom.
  7. IDC cables – Get some IDC cables and insert them into the headers. Just snapped in the IDC cables in the IDC headers and Voila, you’re ready to go!
