Hello, currently on all 8 neos motors we have cut and crimped in the past go to a rev robotics breakout board. Currently we do not want to use the rev board and would like to be able to plug the motor into the spark max port how it should normally be. Below are the pictures of what we currently have. What crimps and housing and crimper do we need to change them to what they originally were from the factory?
You will need a 6-pin JST PH housing and crimps. You can find these on Digikey, but it’s a lot easier to look for a JST-PH kit on Amazon.
A small generic crimper will work to attach them, but if you can find a crimper sold for JST PH, that will work better. Someone else probably has a PN.
Ugh. It’s a JST-PH 6-pin connector. But, DO NOT try to crimp those yourself. It’s a royal PITA and most crimpers do a crappy job. The good crimper is something like $300.
Instead, buy this:
and then solder the wires. Use heat shrink to cover up the joint.
We wanted to create extensions last year and failed miserably.
Since it appears you already are running with Molex SLs, I’ll bring up our plan this season, which is to make a conversion wire between molexSLs and JST PH. We will probably cut the REV extension wires to do this, and crimp SLs. Then we will recrimp the Neos with the molexSL. This will help us do field repairs easier, and we believe the SLs do a better job on the smaller gauge wire on the neo/neo550.
You could easily do this since you already have SLs on your Neos.
I was thinking JST SM might be wise considering it is buckled. Actually having done some garden automation projects two summers ago, I was thinking Deutsch automotive connectors. Are there obvious pros and cons?
Unfortunately I don’t have any part numbers to give anyone, but we regularly crimp new JSTs on our neos, usually when the build mentor (me) or one of the older build leads screws up while unplugging a motor.
We have used these IDC connectors from JST successfully to repair neo motor cables. They’re compatible with the Spark Max (although they sit deeper, so more care is required to remove them). And no crimps or solder are required.

[edit] we’ve also used them to make extra long encoder extensions out of ethernet cable, but if you do that make sure you give the connector good strain relief.

I still strongly recommend standardizing on Molex SL, for the reasons given here: CAN Wiring - #29 by CarlosGJ
