One last thing that we need to take care of, the cables.

The question is who will need cables, and how many of them.
Since sourcing them usually takes 2 weeks from order to delivery, it's the good time for you to order (from me or someone else, as you wish)

My home made cables are using 1.5mm² copper wires.
according to tables, 16AWG is 1.31mm², 15AWG is 1.65mm²

Price will be
2.5$ for 24"/60cm
3.5$ for 32"/90cm

I can also source cables with 16AWG aluminium wires, the price should be 0.6-0.8$ cheaper than the copper ones.

For those of you who'd want to make the cables or add a connector to existing cables, I'm also able to provide the crimp pins and 6 pins connectors at a fair price:
0.20$ the 6 pins connector, and 0.04$ the crimp pin
