Hey Paul,
I thought that was the part you were talking about!
I can’t wait to see you interface those to the controller! I’ll bet that you ordered them from
GMW Associates - Sentron CSA-1V Hall Effect IC - Price list . At $4.95 each in 10 qty they are a good buy. The AN_121KIT is the off the shelf PCB that mounts directly to the busbar at $35.00.
It would be nice if the CSA-1V circuit could be mounted on the power PCB behind the B+ busbar.
