Gravity: 315MHZ RF Receiver Module

Gravity: 315MHz RF Receiver Module provides a compact wireless data reception solution for short‑range remote control systems and embedded electronics. Based on a superheterodyne ASK architecture and the LR480 RF chip, this wireless receiver board delivers stable signal acquisition and strong interference resistance at the 315MHz band. An onboard SC2272‑L4 decoding chip enables address‑based signal recognition for secure command reception. The radio control receiver is commonly integrated into vehicle telecontrol systems, identification equipment, and automated entry devices. Additional technical resources and integration guidance are available through the product wiki.

Superheterodyne RF Reception for Stable Wireless Communication

This 315MHz remote signal receiver adopts a superheterodyne demodulation structure, offering higher sensitivity and improved anti‑interference performance compared with simpler regenerative designs. Typical sensitivity reaches -108 dBi, enabling reliable reception even in electrically noisy environments. ASK modulation support and a maximum transfer rate of 9.6 kbps allow the radio module to handle typical remote command signals with consistent decoding accuracy across applications such as security systems, remote switches, and automation controllers.

SC2272‑L4 Decoder with Three‑State Address Coding

An integrated SC2272‑L4 latch‑type decoding chip provides hardware‑level address recognition for secure signal matching. The wireless control receiver uses an 8‑bit three‑state address coding switch, where each bit supports high level, low level, or floating states. This architecture enables up to 6,561 unique address combinations, greatly reducing signal conflicts in environments where multiple RF control systems operate simultaneously. Compatibility with common encoder chips such as SC2260, SC2262, PT2260, and PT2262 simplifies pairing with standard RF transmitters.

Flexible Wireless Alternative to Wired Control

Compared with traditional wired communication methods, this compact RF receiving module enables flexible installation without routing control cables across equipment or structures. Reduced wiring complexity lowers maintenance requirements and simplifies upgrades for automation projects. A PH2.0‑3pin interface allows quick electrical integration with microcontroller systems or control circuits, while operation at both 3.3V and 5V supply levels supports a wide range of embedded platforms and electronic designs.

Typical deployment scenarios include wireless vehicle control systems, garage door controllers, remote‑controlled appliances, and electronic access systems. The RF receiver board also serves as a practical building block for hobby electronics, remote automation experiments, and wireless control prototypes where stable short‑range signal decoding and flexible installation are essential.
