Spin Semiconductor

First off to clarify: the assembly house is me carefully hand soldering these onto otherwise pre-assembled boards. I ran into a fourth FV-1 with an unresponsive S1, it was the next one after the other 3. It almost seems like they were grouped together. After more testing and troubleshooting I still ...

The switch is used to connect 3.3V to either S0, S1, or neither, with the resistors pulling down to ground. It's an on-off-on switch, not on-on-on (I mistyped previously).

Ah I see. Super helpful, thank you. Maybe just bad luck on the "infant mortality". No visible bridges and all the continuity and voltages are when and where they should be. It was done with liquid flux (not the water soluble acid kind) but I can't find evidence of issues from it. Still, co...

Hi all! I'm experiencing a strange issue with a couple of FV-1 builds having unresponsive S0 or S1 pins. I have a circuit that's been in production for a while and it uses the FV-1 in a pretty conventional way. An SPDT on-on-on with 10K resistors connects 3.3V to S0, S1, or neither, to select from 3...
