so:

* connection from PCB1 (main board) to PCB2 (EC): USB, power-on /
reset, VREFTTL, power.  err... that's all
* connection from PCB2 (EC) to PCB3 (Power): I2C and IRQs (for
BAT/CHG), Power, GND.  err.... that's all.
* connection from PCB1 (main board) to PCB3 (EC): Power.  err... that's all.

i probably missed out the "reset" button but it's just a GPIO.  actual
power-on of the Card is handled by the STM32F072.

so, great question johnathon.
