    Documentation

    • KT0803 radio transmitter datasheet

    Usage

    Important: make sure you properly setup the I2C pins especially for ESP32 before creating the I2cDevice, make sure you install the nanoFramework.Hardware.ESP32 nuget:

    //////////////////////////////////////////////////////////////////////
    // when connecting to an ESP32 device, need to configure the I2C GPIOs
    // used for the bus
    Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);
    Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);
    

    For other devices like STM32, please make sure you're using the preset pins for the I2C bus you want to use.

    Hardware Required

    • KT0803
    • Male/Female Jumper Wires
    I2cConnectionSettings settings = new I2cConnectionSettings(1, Kt0803.DefaultI2cAddress);
    I2cDevice device = I2cDevice.Create(settings);
    
    // The radio is running on FM 106.6MHz
    using (Kt0803 radio = new Kt0803(device, 106.6, Region.China))
    {
        // Connect a sound sources to the 3.5mm earphone jack of the module
    }
