Gravity: 315MHz RF Receiver Module (ASK, Superheterodyne)

The Gravity: 315MHz RF Receiver Module is a compact wireless receiver designed for simple remote control and data projects. Featuring superheterodyne demodulation and an onboard decoder, it provides reliable radio frequency reception for hobbyists, students, and makers building automated systems. Its plug-and-play design ensures straightforward integration into various microcontroller environments.

Superheterodyne ASK reception

The module operates at 315MHz using amplitude-shift keying (ASK) modulation combined with superheterodyne demodulation. This design ensures stable radio frequency signal capture and effective noise suppression.

Integrated SC2272-L4 decoding

Equipped with an onboard SC2272-L4 decoding chip, the board processes compatible incoming RF transmissions directly. This onboard decoding handles signal interpretation so your main controller receives clean output data.

Standard Gravity interface

The board features a PH2.0 3-pin interface for fast, solder-free wiring to expansion shields. This standard connection allows simple integration into development setups and educational prototyping boards.

Dual-voltage power support

Designed for broad hardware compatibility, the module supports both 3.3V and 5V operating voltages. This allows direct connection to 3.3V platforms like modern microcontrollers as well as standard 5V development boards.
