FM Tuner Evaluation Board - FM receiver module with Si4703 chip

Description

Module with FM receiver Si4703, which is a single-chip FM stereo radio tuner with an integrated synthesizer. The system supports the RDS (Radio Data Service) and RBDS (Radio Broadcast Data Service) standards, which allow displaying data such as station ID and song name. The module has a built-in headphone jack and allows you to receive radio waves on the 76 to 108 MHz band without the need for an additional antenna, because this role is performed using a headphone cable or an audio cable (at least 90 cm long). The board has all the main pins, including 3.3 V and GND power supply as well as SDIO and SCLK for I2C communication. The RST pin can be used to easily reset the chip, and the SEN pin allows the user to change the functionality mode of the IC. Additionally, the GPIO1 and GPIO2 pins have been introduced, which can be used as general input / output pins. Full documentation of the module with examples and the Arduino library is available on the product page.
