400–470 MHz UHF/NFM Transmitter Module

The board transmits audio in the 400–470 MHz UHF band using NFM, the narrowband mode used by many analogue walkie-talkies. Its small format suits electronics projects where a separate transmitter stage is needed.

400–470 MHz UHF/NFM Transmitter Module

The stated default frequency is 409.6 MHz, and operation requires a 1.8–4.2 V supply. Match the receiver frequency and modulation, and use suitable antenna and circuit connections for your project.

Transmission range is described as environment-dependent and should not be treated as guaranteed. The module is semi-finished electronics; it needs a compatible power source and integration into a working system.
