Si4707 Weather Band Receiver Breakout

Description: Weather-band radio is an awesome service on the 162.4 to 162.55MHz band in the US, Canada and Bermuda that broadcasts normal and emergency weather information. It's a good way to get a weather report and a great way to stay informed during a severe weather emergency.

The Si4707 from Silicon Labs is a fully integrated weather-band radio with 1050Hz detection (the tone used to indicate a watch or warning).

This breakout board makes it easy to integrate the Si4707 into your next project! Simply provide 3.3V and plug a speaker or headphones into the on-board 3.5mm audio jack.
