This module is a kind of expander or break out board for other modules.
If you have modules with outputs on the backside via pinstrips, then this module may help you with getting those signals buffered and bringing them to jacks on the front.


  • 8 signal input pins on the backside.
  • 8 buffered output jacks on the front.

The connections on the back (including GND pins) can be made with female-to-female dupont cables (not included).

The eight outputs have a protecting 1k resistor before the jack.

The upper and bigger pinstrip with 2×8 pins is the 8 inputs and their GND-pins.

The lower and smaller pinstrip with 2×5 pins is the power connector.
Make sure to get the orientation correct for the power connector.
The -12V side of the cable is usually marked with a red stripe, and the text “-12V red stripe” is printed on the PCB for guidance.
