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.
Connector J2 (Expansion Connector -2)
Power the Kit
The following steps provide detailed instructions to power the kit. Note that these instructions are
available in brief in the quick start guide.
Insert Battery
Two AAA size batteries are provided with the kit. Insert these batteries in the battery holder provided
on the bottom side of the kit. Ensure polarity of the battery, as shown in the following figure.
