Battery holder and pin header compatibility

Battery holder and pin header compatibility

Closed this issue 3 years ago · 4 comments

Hey
It seems that either J2 or BH1 are the wrong part number here.
I ordered according to BOM (S2B-XH-A(LF)(SN) and PRT-09925). They do match, but the polarity is reversed. The VCC on battery holder matches the GND on the pin header/PCB. The one shown in your Youtube video has the right polarity though.

Please see the attached pictures:

Here's yours. Please note the difference:

I think yours is defective - see https://www.sparkfun.com/products/9925 which shows the pinout of mine being the same as in the sparkfun photo.

Yes. Digikey is selling the wrong product under Sparkfun PRT-09925. Just reported the error to them.

Might have been an error in that batch, as I bought it in December and it was the "right" way around. If you've got a small screwdriver or anything (nail) it's easy to switch the contacts as in that photo.
