Custom Extension Module

a pair of solderd D-Subs later


Testing them also didnt kill my Controller and the Analyser is able to read CANbus so im assuming they are “to spec” ?

Pinouts of the Snapmaker cabels, only CAN and power are used in my Connectors, Step and such arent requierd for my usage so they are shrinked off.

DB9 Connector Pinout:
2: CAN_L
3: CAN_GND
6: GND
7: CAN_H
9: CAN_PWR
Pin 3 and Pin 6 are connected inside the D-Sub Connectors in my case. (as no PCB bridge exists sofar and having 2 GND connections sounds better)
CAN_PWR is carrying 24V (didnt see a voltage described in the Spec.)
