Expansion Connector Two (Connector J2)
Using the VDD and GND signals available in J2 connector, the kit can be powered from external
power supply. Note that this power supply is gated through CapSense based power button circuitry.
CapSense controller receives 200 mV less than what is applied to connector due to the drop out
across the power button switch circuitry. External supply should be greater than 2.0 V and less than
3.8 V to provide 1.71 V to 3.6 V supply to the CapSense Controller.
