Battery holder and pin header compatibility #9

Closed mehdideveloper closed 2 years ago

mehdideveloper commented 2 years ago

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:

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.
