T030 76M-108M 10mW FM Transmitter Board FM Transmitter Module for Stereo Wireless Audio Transmission
Description:
The FM transmitter board uses an advanced MCU microcontroller. It has a novel design and superior performance. The transmitter chip utilizes a digital PPL tuning method, ensuring there is no frequency offset or drift. Even if you grab your antenna with your hand, it will not have any effect on it. The working state of the chip is controlled by the program.
The transmitter module uses a stereo transmitter IC. The transmission frequency of the stereo transmitter covers the FM bands of China, Japan and Europe. The frequency band is adjustable from 76MHz to 108MHz. The input coupling and signal encoding are designed through precise algorithms. The sound is demodulated and played back. Whether it is high pitch or low pitch, this module has first-class performance. Its sound quality is very good, and the distortion rate and signal-to-noise ratio have reached the broadcast standard.
Features:
* Dual-channel FM stereo transmitter

Product Instructions:
- button: Short press the button to reduce the frequency by 0.1MHz. Long press the button to adjust quickly.
+ button: Short press the button to increase the frequency by 0.1MHz. Long press the button to adjust quickly.
VOL button: Short press the button to cycle through volume levels 1 to 5.
Volume Adjustment Instructions:
The audio signal input has 5 volume levels. Level 1 is the lowest volume, and level 5 is the highest. The default volume is set to level 3.
The principle of adjusting the input signal's volume is to set it to a higher level without distortion. This ensures the best possible signal-to-noise ratio during playback. Beginners can use the default volume without making adjustments.
Package Included:
* 1 x FM Transmitter Board
