4-Channel Wireless RF Remote Control Transceiver Module (315MHz, Non-Locking)

Description

This 4-channel RF remote control system consists of a handheld 12V transmitter and a compact 5V super-regenerative receiver module. Operating at 315MHz using ASK (Amplitude Shift Keying) modulation, it provides a reliable, license-free wireless link for control and automation. The system employs fixed-code encoding, where each transmitter has a pre-programmed unique ID, allowing the receiver to validate signals for basic operational security.

The receiver module outputs momentary high logic levels on its four data pins (D0-D3) corresponding to the four transmitter buttons. A dedicated VT pin provides a valid transmission indicator, which can directly drive a small relay or LED. For optimal range, a quarter-wave monopole antenna (approx. 17cm) can be attached to the receiver’s ANT terminal. The module is designed for easy integration into projects requiring wireless switching, remote activation, or as a simple input source for microcontrollers.
