Super capacitor polarity

Hi,

How should the super capacitor be mounted on the UPS Pico HV4.0 board? The manual only says "mind the sign '-'". But when I look on the board, I don't see a '-' sign clearly attributed to the capacitor headers. There is a '+' sign next to the header that is closest to the edge (see attached picture). Is that the indicator for the capacitor polarity?

Best regards,
Vic

Hi,

If you see better, then indicate the "-" sign on the PCB. However as we mostly finished the manual and newer firmware, please be patient some hours more for official release of them.

@vicmortelmans That's not a capacitor, that's buzzer connection I made the same mistake :). Supercapacitor is 2 pins labeled S CAP close to it.

 

The minus connector is one closer to the rpi pin header, there is minus sign next to it

Hi, thanks, I believe I get it, but your second picture is confusing me again, because the capacitor's gray band that indicates the negative polarity is visible and it is turned away from the GPIO header.

Is this just a mistake in the picture?

Best regards,

Vic
