1. Features
  • Eight opto-isolated, zero-crossing control channels
  • No library needed - control is as easy as turning a LED on and off
  • Shield is compatible with 5V or 3.3V Arduinos
  • Integrated 1.5A linear regulator (LM317) to supply regulated DC power to external inverter
  • Linear regulator preset to 3.3V, but can be changed via PTH resistors, or bypassed entirely
  • External inverter required, not included
  • Comes without headers, soldering required
2.Appliation Area
  • Outdoor building decoration and lighting
  • Advertising and festival decoration
  • Wearable DIY applications

3.Specification Parameter
  • AC input voltage: 220V   
  • AC maximum input voltage (max.): 600V   
  • Maximum current: 20A    
  • Linear regulator output voltage range: 1.2V--37V  
  • Linear regulator output current: 1.5A

This expansion board is designed by ICStation which can controlling up to eight strands of electroluminescent wire. EL wire is flexible plastic cord that glows brightly when high-voltage AC is applied to it. It’s available in numerous colors, runs cool, and requires very little current, but can be difficult to work with because of the high-voltage requirements. The El Escudo Dos contains circuitry to safely switch high-voltage AC on and off, allowing you to create animated displays or whatever else your imagination can come up with.

The main chip is LM317, MOC3063 and Z0103MN.
LM317 is used to provide the required external DC power with inverter.
MOC3063 is to provide the full isolation of the photoelectric's zero-crossing.
Z0103MN is to drive the lights glowing, as Z0103MN can only goes through AC.

Here are two ways to connect to the external power:
1. Connect the external AC to the AC FROM INVERTER port
2. Connect the board to the external 12V DC power supply. Then the board can provide the expansion board with DC.
Connect INVERTER between the DC TO INVERTER port on the expansion board and AC FROM INVERTER port, and the INVERTER output AC to power for the expansion board.

It's very simple to connect the light strands that you only need to connect the A - H port of the light strands.  No need to worry about the positive and negative issues when you do the wire connect as the light strands are controlled by AC.

5. Wiring Diagram & Size


  • Because that the expansion board controlled by AC, please do not plug the connector the power switch when the power is ON, or touch the metal on the blank board.
  • Please kindly have a check if the optocoupler has been damaged when any of the channel cannot work well. Because there are so many optocoupler on the expansion board.
