New Pulse Rifle Wiring

To squeeze our pulse rifle counter board into an even smaller size we have changed the wiring method. Instead of individual JST PH connectors for each thing we now have one single integrated connection that contains all the connections in one plug.

Not only does this make the connector smaller, but it should also now be impossible to plug the wrong thing into the wrong place. However it does become slightly trickier to do the wiring in the first place.

The connector looks like this, and has 8 connections:

From right to left the pins are:

  1. Reset (this is part of the programming interface, you can ignore it)
  2. Power +
  3. Ground
  4. Speaker +
  5. Speaker -
  6. LED Output
  7. Magazine Input
  8. Trigger Input

You may notice that there is only one Ground connection. That single connection has to go to the battery and the switches for the magazine and trigger. If the LED driver is being powered by a different power source to the rest of the system then it should go to the ground of the LED driver as well.

Of course, it doesn't have to go right to that pin, just connect to something that is itself connected to that pin, such as the negative of the battery.

To make wiring easier we include a small wiring harness in the package for you. The ground pin on this harness actually has two wires going to it, one for the battery and the other for you to connect to your buttons / switches:

The wire colours are as follows:

  • Orange: Trigger
  • Yellow: Magazine
  • Green: LED
  • Blue: Speaker -
  • Grey: Speaker +
  • Single Black: Switch / LED ground
  • Red & Black Paired: Power + (red) and - (black).

Here's a wiring diagram to show you how everything fits together:

The connector is a 2mm pitch "JST PH" 8-pin. You can find them pre-wired (though with only one wire per pin) on eBay quite commonly if you want to create your own wiring.
