Pin Count:
- More is better, at least X JE – Don't know what systems are on boards yet, but I doubt you'll have much trouble with this
- 22 at 3A, 34 at 1A
Max Current:
- At least X
- JE – Don't know what systems are on boards yet, but I doubt you'll have much trouble with thisSee above
Max Voltage:
- At least X 4S LiPo (25V?17V)
Fabrication Method:
- Board-independent; connector functionality should not rely on certain mechanical characteristics of the PCB
- Reversible: connector should not be irreversible or irremovable, in event of damage
- Requires no specialized, high-cost tools.
- Bonus points; ability to act as a wire-to-board connector as well, for use in debugging.
...
- Bonus points if the connector is a basic part or carried by JLCPCB already.
- Reduces ordering complexity and potentially cost ($3 extra per each non-basic component) - JLC doesn't basic stock any connectors.
