How to Use

• First, you need to create a KT0803L object. After that you should call InitializeAsync() to initialize.

KT0803L kt = new KT0803L();
// 108 MHz
await kt.InitializeAsync(108);

• And you can input the audio through the 3.5mm earphone jack. After that, turn on your radio, listen to FM 108 MHz.

• If you want to close the sensor, call Dispose().

kt.Dispose();
