Designed for low-voltage applications, the TEA5767 Module is a single-chip FM radio integrated circuit that is perfect for use in microcontroller platforms such as Arduino and other 3.3V development boards, as well as embedded systems. This multipurpose chip has an integrated FM demodulator and intermediate frequency selectivity. Connecting to other development boards is simple because of its compatibility with the I2C communication protocol. It can operate as a standalone radio receiver with very few extra parts. The TEA5767 can tune into FM stations in the US, Europe, Japan, and India thanks to its support for frequencies between 88 and 108 MHz. Details: 3.3V is the operating voltage. Interface: SDA and SCL pins for I2C high sensitivity and an input amplifier with low noise. For signal optimization, use RF AGC (Automatic Gain Control).
