What is the point of a 40-pin connector when the spec sheet only indicates that two of them are used (exactly as one would expect for a battery)?

- jetrink 7y agoTwo reasons: it's a standard form-factor, which makes it easier to work with and the additional pins hold it securely to the board.
- newnewpdro 7y agoPresumably the battery+shielding sets minimum volumetric requirements, and those form factors meet them while providing easy and robust circuit integration using existing standards.

- Nextgrid 7y agoMounting? You solder all 40 pins to hold the device onto the board even if you only need 2 pins. Presumably the pins are repeated across all sides so you can pick any pin that makes routing more convenient.
- gliese1337 7y agoThat would make sense, but according to the spec sheets the pins are not repeated--only two of them are functional, the rest are dead.
