I’m in the last stages of a Sparkfun S3 => XL conversion. Its the hardest part because the XL has a pre-assembled wiring harness but the Sparkfun is all terminal strip based. I basically have two choices:
- Rip off all the terminals and just solder / shrink wrap everything
- Wait for the molex connectors I ordered from Digi-key and use them for the motor connections (the controller needs bare wires so not much point in doing anything with connectors).
Soldering would be more solid in a hostile environment (vibration, dust, etc.). Connectors are good for flexibility although not sure how often I would actually be disconnecting things
