Digital Radio Receiver Module Stereo Wireless FM Modules with LCD Display 50Hz‑18KHz

Summary

• Advanced Technology: The circuit board uses advanced digital audio signal processing technology (DSP) and FM phase locked loop modulation technology (PLL) to make the sound quality more real, the performance more stable, and working frequency has no deviation.
• High Quality Function: The circuit board has 30 level digital volume adjustment, which can be easily completed by key operation, automatically memorizes the data before the power failure, and the speaker and earphone output automatically switch.
• Quartz Crystal Frequency Stabilization: The circuit board with quartz crystal frequency stabilization is adopted, and the receiving frequency will no longer drift when the temperature changes.
• Audio DSP: The circuit board uses professional audio DSP to analyze and process the audio signal, will automatically mute when there is no signal or weak signal, etc. FM noise floor is large, and get rid of the annoying rustle of traditional FM radio when there is no signal or weak signal.
• LCD Display: This is a radio circuit board with a more intuitive and accurate LCD display, with extremely low power consumption and minimal noise interference, and supports serial communication control, use all functions such as a computer or MCU to control the module.
