5) Use a linear regulator for the supply if possible. If a switching power must be used then see
the section on choice of power supply.
6) If a switching supply is present on the same mother board, and uses an inductor, consider
rotating the inductor to obtain the least coupling with the module antenna.
7) Preferably power the beeper from another supply. Beepers can draw large current that can
cause the module supply voltage to dip momentarily causing a module brown out reset or
other erratic malfunction.
Note. Low power regulators are less expensive, easier to configure, take up less room and noise
is easier to control. If long read-range is not critical to your application, consider the
ID-Innovations micro power range of pin compatible modules; these typically draw less than 100
micro amperes at 3v.
