FM radio module stereo RRD-102 ver.2.0 based on the RDA5807M chip is used to create projects where you need an FM radio receiver. 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 half-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.


Key Features:

  • Supply voltage: 1.8 - 3.3 V
  • Frequency band: 50 MHz to 115 MHz
  • Configurable step between channels - 200 kHz, 100 kHz, 50 kHz, 25 kHz
  • Total Harmonic Distortion: 0.15 - 0.2%
  • Ambient temperature: -20 to +75°C
  • Operating current consumption: up to 21 mA
  • Standby current consumption: 5 μA
  • Maximum I2C Frequency: 400KHz
  • Module dimensions: 11 x 11 x 2 mm
  • Weight: 1g
  • Supports RDS/RBDS
  • MSOP package (10 pins)
  • The frequency synthesizer is fully integrated into the microcircuit
  • Management interface: I2C
  • Automatic gain control
  • Digital Adaptive Noise Reduction
  • Support for audio output in both mono and stereo
  • Receive signal strength indicator (RSSI) and SNR
  • Sound control and mute function
  • Bass amplifier for headphones
  • Load at the output of the audio channel 32 Ohm
  • Built-in LDO controller
