Si4703 FM Tuner Breakout Evaluation Development Board Radio Frequency Receiver Replaces SparkFun WRL-12938 V13

• ProTechTrader's Si4703 is Designed to be compatable replacement of the SparkFun FM Tuner Evaluation Board WRL-12938 V13 with matching pinout of GND 3.3V SDIO SCLK SENRST GP101 GP102 - Note: This matches the latest style (v13) with the 3.3v and GND pins switched compared to the older V11 SparkFun WRL-10663 breakout board
• FM Radio frequency range: 76 ~ 108MHz - Module operating voltage 3.3V - Programmable de-emphasis (50us/70us)
• Enables you to tune and recieve FM radio stations & the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information
• Communication interface: 3-wire system (maximum 2.5MHz), module default 2-wire system IIC (maximum 400KHz) Please Note: Soldered Header not Included
• Keep in mind, by plugging headphones into the 3.5mm audio jack, you effectively use the cable in your headphones as an antenna! Therefore, this board does not require an external antenna if using headphones or a 3.5mm audio cable longer than 3 feet.
