You already have the maximum available quantity in your cart.
The FM transmitter module with LCD display is a ready-to-use assembled board that converts sound from a computer, mobile phone, player, or microphone into a radio signal and transmits it on a selected frequency in the range 87.0–108.0 MHz. You can receive the transmission on any FM radio within range. The transmitter operates with standard frequency modulation and its output power is 100 mW. The set frequency is displayed clearly on the LCD screen on the front of the board, so you always know which station to tune your radio to. The module is popular among DIY enthusiasts, radio amateurs, teachers, and electronics students.
Sound can be fed into the module in three ways. The LINE input and USB input transmit sound in stereo, while the MIC input operates in mono mode. When connected via USB, the module behaves like a sound card in the computer. Frequencies are tuned using buttons – a short press changes by 0.1 MHz, while a long press changes by 1.0 MHz. Additional buttons are used to adjust the volume and pause transmission. When the school broadcasting mode is activated, the transmission range expands to 76.0–108.0 MHz. A separate connection is provided for the antenna, and the recommended length for the whip antenna is 75 cm.

The transmitter can be used, for example, to transmit music from a computer to an old radio without Bluetooth, to amplify a workshop or garden, for experiments with radio technology in schools, or as part of your own project. Due to its low power consumption, it can be powered from a USB port, charger, or power bank. When in operation, please comply with local regulations for broadcasting in the FM band and choose a frequency that is not used by any radio station. Protect the board from moisture and check the polarity before connecting the power supply.
The FM transmitter module with LCD display is a simple way to get sound from any source into a regular radio. It offers stereo input LINE and USB, a microphone input, and precise digital tuning with immediate frequency control on the display. Power supply 3.0–5.0 V and a consumption of only 35 mA allow it to operate from almost any USB source. The ready-made board is prepared for use immediately after connecting the power supply and antenna. It is a practical helper for DIY enthusiasts, teachers, and anyone who enjoys experimenting with radio.
