3.1 Power Supply
S require a power supply with the following characteristics:
Typical: 3,0V
DC
, min.: 1,8V
DC
, max.: 3,6V

, thereby delivering > 25 mA peak
S is designed to be powered from 3V coin cell batteries e.g. CR2032 directly, or any
other power source complying with the given requirements. For optimal performance a stable
supply is recommended.
