# Si4735/Si4732 Digital Radio Breakout Board

This is a simple breakout board that you can use for both the Si4735/32 chips by Silicon Labs. This designed was made after the [Si4735 Arduino Library](https://github.com/pu2clr/SI4735) was published, to explore it's functionality without having too much soldering (the Si4735's SSOP-24 package is just 0.65mm pitch!)

Simply solder one chip at a time, and all supporting passive circuitry.

All parts can be sourced cheaply at LCSC.com, except for the main IC.

## Programming

The [Si4735 Arduino Library](https://github.com/pu2clr/SI4735) is used to send commands to the chip, with the microcontroller of your choice. This board has been tested with the ESP32, but any other microcontroller that can safely supply 100mA of current through the 3.3V supply is fine. Minimally connect the RST, SDA, SCLK, 3V3, GND pins to your microcontroller to get started with the examples provided in the library.

If you would like more detailed information, check out the [official programming guide](https://www.silabs.com/documents/public/application-notes/AN332.pdf) from Silicon Labs, on what commands to send over the I2C bus.

## Importing the PCB Documents into EasyEDA

Download the .json files and import it into EasyEDA on your browser. You should be able to edit the board and generate your own Gerber. If not, you can use the Gerber in this repo.

## Sending PCB for Manufacturing

To manufacture the PCB, send the Gerber and the NC Drill file under the output folder to the PCB House. They should be able to accept the PCB (it conforms to standard PCB design rules).
