I have an unopened sparkfun LiPOLY BATTERY CHARGER from about 10 years go. I believe the SKU is/was 187496 or SF-RTL-09876.

Looking for any documentaton such as techincal description and hookup guide.

Thanks in advance!

That’n must be even older! The one I linked is from ~12 years ago

The good news is that the one you have and the one above are nearly identical in terms of function…your version has fewer components populated but the basic wiring scheme and jumper adjustments work the same

Compared with the newer one

yours doesn’t have the barrel jack or the charge current external resistor but the rest of that guide should be applicable

Just a side note: I would not try to charge the lipo in that package (use a newer one, ensure the polarity matches…after a decade or more they can get a bit sketchy

Are there more parts obfuscated or does the package contain just board & battery only?
