Power Supply
The LA02303B requires a single nominal supply level of 3.3V. All the necessary decoupling and
filtering components are included in the module. To secure the best RF performance, the power
supply for the module is recommended to have the output current higher than 30mA and have the
ripple voltage less than 100mV
