RDA5807M FM Radio Receiver Arduino

FM radio module stereo RDA5807M for Arduino is used to create projects where you need an FM radio receiver.

This module is fully software compatible with a similar module TEA5767. The RDA5807M can receive RDS/RBDS data, but it needs a good antenna. The range of received frequencies is 50 MHz - 115 MHz, which means that the module can receive stations on forgotten VHF waves (ultra-short waves).

The module is controlled either from the Arduino controller, or from another microprocessor control device via the IIC interface, using special programs.

To use the module, you must first assemble a layout based on it (connect power, connect to the controller, connect the antenna). Also, for normal work with Arduino controllers, you need to use the library. After that, you can start working.

FM radio module stereo RDA5807M for Arduino has 10 solder terminals for connecting power, antenna, microcontroller.

RDA5807M stereo FM radio module pins for Arduino:

IIC interface pins 1 and 2 (1-SDA, 2-SCL);

pin 3 Busmode (bus setting, not used);

pin 4 Write/Read (not used);

pins 5 and 10 supply voltage (5-VCC, 10-GND);

pins 8 and 9 audio output (8-audio L, 9-audio R);

pin 7 RCK External clock input (not used);

pin 6 antenna.

The module can be powered either from the Arduino controller, or from another microprocessor control device, or from an external power source (battery power supply). The module can operate at a voltage of 2.7 - 3.6V.
