6. Getting started
6.1 Setting up the hardware module
1) Connect the Touch sensor plate as shown in fig. 1.
2) Connect a DC power source (2V-3.3V) to the pins labeled “BAT” (see fig. 1)
6.1.1 Smart Lock power connection
As the Smart Lock is intended to be operated by a single cell battery (e.g. CR2
~780 mAh or CR123 ~1,450 mAh) with a nominal voltage of 3V (typically ~2.5 V
depending on load current). An ultra-low-power step up converter which operates down
to below 1 V input voltage is used to generate 3.3 V circuitry supply.
