I have this trackball - https://na.suzohapp.com/products/trackballs/56-0300-16 which has green boards on the sides and one of the boards accepts the wiring harness which is what i dont have.
One part of the green board has 4 pins which i was assuming is the usb portion and the other part of the board has i think 6 pins which i believe is for adding some push buttons.
You have the less-common version 55-0301-00
PCB with a built-in optical encoder IC chip.
The USB cable connects to J1. (upper left corner)
There are 4 wires in a USB cable: (J1 right-to-left in pic above)
- Data -
- Data +
Check out the wiki page here
for the pinout (right side) so you can verify which wire is which using a multimeter.
Do not trust wire colors since some cables use non-standard wire colors. (i.e. red isn't always 5v and black isn't always ground)
One way to hook it up is to get a cable like this one
. (search for "USB dupont" for other options)
- Pull the 4 pins mentioned above out of the 5-pin Dupont connector body -- ignore the shield wire, you don't need it.
- Connect the female cable pins to the J1 male header pins on the 55-0301-00 PCB.
- If you don't have a 1x4 connector body that will work with the PCB, you can use heat-shrink to insulate the individual female pins.
To pull a pin, gently lift the plastic arm (next to the exposed metal) with a straight-pin or the tip of a knife and pull on the wire.
Not sure what you mean though by 'red boards'.
Most Happ trackballs come with these optical boards -- also seen in the first picture in this thread.
