Description

SI4732 Allwave DSP radio controlled by Pi Pico

Raspberry Pi pico can control SI4732 via I2C interface.

The Pi pico program that controls the SI4732 can be found on GiHub.

Additional functionalities are needed when using SI4732.

Audio power is insufficient and sound has distortion,

so it need to add amplifier with lowpass filter.

And high-frequency amplification is also required.

The circuit diagram shown here realizes them.

The Operational Amplifier NJM4580 is used for audio amplifier.

Transistor S9018 is used for high frequency amplification.

Buttons for operation are connected to pin headers installed on the board.

The display unit is connected to the I2C of Pi pico.
