Crimp connectors housing and Pre-crimped cables

Hi all

I did a lot unsuccessful research to find a modular system with
- all kind of 1xN and 2xM connectors required to integrate Najda and WaveIO boards
- long length (60cm) pre-crimped cables, as most often Dupont cable are available only in 20 to 30, maximum 40 cm
- multi-color cables which makes much more easy to install

until I found out Pololu - Crimp Connector Housings where they have all cables and housing. Order is being handled, will tell if not ok.

Hope that helps

Hi SAC
This thread will become a wonderful resource as Najda matures.
Want to add one power supply that is plentiful in Ebay US site for around $40 new. Specs look good for the SLT series.

I have bought the Sola SLT12-40204-12T but it didn't work out.
You have to watch out for the type of housing. The H2 does not have the -12V/GND/+12V output the Najda needs.. It has 2x +12V outputs.
The H1 housing does have the correct outputs (1x 5V and the +12v/gnd/-12V)
