DSP PLL Digital Stereo FM Radio Receiver Module 87-108MHz With Serial Control Frequency Range 50Hz-18KHz

1. Utilizes advanced Digital Signal Processing (DSP) and Phase-Locked Loop (PLL) modulation technology for more realistic sound quality, more stable performance, and no frequency drift during extended operation.

2. LCD display provides a more intuitive and accurate reading experience, with extremely low power consumption and minimal noise interference.

3. 30-level digital volume adjustment, easily controlled with button operation.

4. Automatically remembers data from the previous power outage.

5. Automatic switching between speaker and headphone output.

Employs quartz crystal frequency stabilization, preventing frequency drift due to temperature changes.

Uses professional audio DSP to analyze and process audio signals, automatically muting when there is no signal or weak signal, eliminating the annoying hissing sound of traditional FM radios in these situations.

Employs an incremental digital rotary encoder for volume and frequency adjustment, providing a superior feel, precise positioning, stability, durability, and 360° rotation without blind spots.

30-level digital volume adjustment range

Supports serial communication control; can be controlled by a computer or MCU with a serial port to control all the module's functions.
