Moar pictures of the Siemens EPD-1 guts


portion of the flat flex cable
Traces from top to bottom:
Ground (to case)
Negative power (ground)
Positive power
unknown*


The lower large pad is the negative battery terminal, the upper positive. This is where I connected a Li-ion cell and the unit did something.

The weird springy sheet metal clip...thing...holds this:

Absolutely no idea WTF

???

The center pin of this weird thing is the unknown* trace, the case is connected to ground.
