"This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an Arduino library for the SI473X BROADCAST AM, SSB and FM/RDS RADIO RECEIVERS. Frequency ranges of AM and SSB modes are 150kHz to 30MHz, and FM mode is 64 to 108 MHz."

⇒ Ground = Pin G
⇒ Operating Voltage = Pin V
⇒ data = pin T
⇒ Power On/Off = Pin P1
⇒ PIN P1 is an on/off switch and must be set to logic low.
