Wireless FM Transmitter Module — mini green micro module designed for compact audio transmission across the FM broadcast band. Operates from 0.79V and covers 88 MHz to 108 MHz. Bluetooth compatible and offered in a small 'mini bug / dictagraph' form factor for tightspace integration and DIY projects. Key benefits Add wireless audio to legacy FM radios: converts Bluetooth or wired audio sources into an FM signal receivable on standard FM radios. Lowvoltage flexibility: wide operating range (0.79V) lets you power the module from small batteries, USB power sources, or existing lowvoltage systems. Full FM band tuning: 88 MHz–108 MHz coverage provides flexible channel selection across the standard FM broadcast range. Tiny, easytointegrate form factor: the mini green micro 'bug' size fits compact enclosures and prototype boards where space is limited. Bluetooth compatible: accept audio from Bluetooth devices for a wireless source option without a wired connection. Key attributes Functionality: Wireless FM transmitter module for audio transmission within the FM band. Voltage range: 0.79V (supports lowvoltage battery and common power supplies). Frequency range: 88 MHz–108 MHz (standard FM broadcast band). Compatibility: Bluetooth compatible for wireless audio input; works with standard FM receivers. Size and appearance: Mini / micro module in green PCB form factor, marketed as a mini bug / dictagraph style device. Intended use: Module for integration into DIY electronics, incar retrofits, portable audio solutions, demonstration and testing setups. What makes this module unique Combines a very low minimum operating voltage with broad FM band coverage in a very small package. Designed as a mini 'bug' / dictagraph style micro transmitter so it can be embedded where larger units will not fit. Bluetooth compatibility provides a modern wireless input option for a classic FM output, bridging older receivers with current devices. Recommended use cases Incar audio retrofit: Give older vehicles without AUX or Bluetooth a wireless audio source by pairing a Bluetooth phone to the module and tuning the car radio to the chosen FM frequency. Portable audio broadcast for events or displays: Use to transmit a local audio feed to nearby FM radios at trade shows, exhibitions, or classroom demonstrations (ensure compliance with local transmission rules). Electronics projects and prototyping: Ideal for hobbyists, students, and engineers building small transmitter projects, testing FM receiving circuits, or demonstrating FM modulation concepts. Installation and basic considerations Power: Supply any stable voltage between 0.7V and 9V according to your application and wiring. Use proper decoupling and safe wiring practices. Tuning: Tune within the 88–108 MHz FM range to find a clear channel. Exact tuning method depends on module controls and your receiver. Compatibility: Works with Bluetoothcapable audio sources and standard FM receivers; confirm receiver supports the selected FM frequency. Compliance: Operation of FM transmitters is subject to local regulations. Verify allowed power levels, permitted frequencies, and licensing requirements before use. What this product is and is not This is a compact wireless FM transmitter module (mini green micro) with Bluetooth compatibility, operating at 0.79V and covering 88–108 MHz. It is intended for legitimate audio transmission, prototyping, and integration. Do not use to violate privacy, intercept communications, or operate outside local legal limits.
