New PCBs have arrived. Revision 14!
We ordered these boards about 17 days ago. That is a great turn around time. It did take a week of negotiating to settle the details of the order, but I suppose you have to take the good with the bad.
The main difference between this version and the one I’ve been using is that I’ve significantly modified the constant current driver circuitry, rerouted a couple sense lines, and attempted to fully protect all the inputs and outputs from large transient spikes that could grenade the delicate silicon on the board.
If I am correct, this is ready for the road or trail!
