2Pcs 88-115Mhz Wireless for Fm Transmitter Module with Adjustable Microphone
Features:
*FM Transmitter Module: This FM radio transmitter module operates within the frequency range of 88-115 MHz and includes a built-in microphone, making it suitable for various audio transmission applications.
*Operating Specifications: The module functions with an operating voltage of DC 2V to 9V and draws a current of 9mA at 3V. It has a reference transmission distance of up to 100 meters in open terrain, while indoor environments with obstacles can achieve distances of 10-30 meters.
*Frequency and Reception: The operating frequency ranges from 85MHz to 115MHz, typically starting between 99 and 101 MHz. It can receive FM radio signals across the 88-108MHz range, compatible with devices that have FM reception capabilities.
*Technical Details: Frequency control is achieved via an adjustable capacitor, and the output impedance is rated at 50 ohms. The compact size of the module is 2 cm x 1 cm, and it allows for voltage testing at 3V, significantly enhancing voltage levels.
*Package Contents: The package includes two FM radio transmitter modules with microphones, providing a convenient solution for users looking to implement audio transmission projects.
