Pinout for battery PCB

Post by forum_admin » Tue Apr 26, 2016 10:15 pm

See below for the pinout of the PCB and spring fingers that connect to the battery.

With this you can easily test a camera using a bench supply, 10V with 2A current limit. The pattern of the current draw allows some basic diagnostics of the camera. A bit of a surge that backs off is good, as the temperature regulation of the sensor sorts itself out.

The base pins (for charger supply input and external power) are wired via the PCB to pick up some EMC components.
These all go onto the 6 way wiring loom to the camera

The colour code on the lead is:
Black = 0V / case
Purple = battery temperature feedback for charger (10k thermistor) 'T' contacts
Red = Battery +ve
Blue = Centre pin from 'AA' pack for battery bar
Yellow = Charging power input (constant current) from pin on base
White = External Power input, from pin on base. Connects after the on/off switch circuit, so power = turns on.
