We looked at several connector solutions to make potential Talon change outs easy during competition. A lot of the polarized solutions we considered had costs of ~$1 per connector and used the small crimp pins that the kids sometime struggle with. Then we discovered the WAGO 222-412 2-terminal block. We bought 50 of these for about $0.35 each at Newark (

We initially used several of the small terminal blocks that come with the annual KOP to wire up the prototype electrical subsystem and had trouble with an unreliable CAN bus. All our CAN communications issues disappeared after swapping in the little WAGOs.
