DSP PLL Stereo FM Transmitter Module w/ LCD Display 87-108MHz

Description

Engineered for reliable FM broadcasting, this module combines a digital signal processor (DSP) with a phase-locked loop (PLL) synthesizer to deliver crystal-stabilized frequency modulation across the 87-108MHz band. The integrated LCD provides real-time feedback on transmission parameters, while the low-noise RF stage ensures clear audio quality with a signal-to-noise ratio exceeding 30dB.

Operating from a 3-5V DC supply, the board supports both stereo headphone and amplified mono speaker outputs, automatically switching between audio channels. Its serial command interface allows for remote control and integration into larger audio streaming or public address systems, making it suitable for developers requiring a programmable FM source.
