Do you know what kind of connector or pins do I need to plug in 2 extra buttons to the back of the Heusinkveld shifter? How many cables are neccesary?
Next to the USB-port, there is also a 4×1 2,54mm female Molex socket. This allows to you interface/integrate the shifter with an external controller, such as our own Sim Pedals USB controller (or any other third party controllers which offers an interface for switches). You will need to build your own cable if you want to use this method. The integrated controller board can be seen from the outside, but it is protected by an acrylic plate.
