Motor wiring

[Kindlabs]

sparkfun’s hobby motor’s wire color is backwards from what you show in wiring diagram. This took me way too long to figure out but hopefully I can help others. Theirs has blue on top and brown on bottom

Hi @Kindlabs thanks for the hint. Can you please point me to their wiring diagram and the one in the ros-mobile-robots documentation that has an issue? The one I found on their website is this:

This seems to show the same (correct) wiring as the one in Remo diagrams:

and the one shown here:

I agree the following text is a bit misleading:

The pins on the product are as follows, when looking at the connector on the housing, motor down/connector up, from right to left. The colors correspond to the included cable when plugged in to the connection slot.

G (Blue): hall power negative
H1 (Green): hall H1 output signal, square wave
H2 (Yellow): hall H2 output signal, square wave
V (Orange): hall power positive
M+ (Red): motor positive pole
M- (Brown): motor negative pole

Would be great if you could clarify the confusing part, so that we can update it in the documentation. Feel free to open a PR yourself as well.

Would it help if the text was changed to:

The pins on the product are as follows, when looking at the connector on the housing, motor right/connector left, from top to bottom. The colors correspond to the included cable when plugged in to the connection slot.

M- (Brown): motor negative pole
M+ (Red): motor positive pole
V (Orange): hall power positive
H2 (Yellow): hall H2 output signal, square wave
H1 (Green): hall H1 output signal, square wave
G (Blue): hall power negative

Or is there some image that needs to be fixed? I think with the original connector, which can only be plugged in one direction, the colors should match to what is shown in the wiring diagram:

Routing the Brown and Red cables of the plugged in connector cable to the motor driver and the rest of it (Orange, Yellow, Green, Blue pins) to the micro controller (teensy) for reading the encoder values has worked so far for me.
