A large tantalum capacitor (C1, 220µF/4V) improves the response of the power supply to current peaks
caused by reception or transmission. Coin-sized Lithium CR2032 batteries are targeted at a maximum
continuous discharge current in the range of 3mA. Such a large capacitor helps to supply enough current
to the MC13213 during a receive/transmit without significant V
dd
voltage drops.
Design doesn’t have any main power switch, thus switch on is done by pressing any button on board and
switch off is done by software (Timeout, Out of range, RF protocol command).
