315M RF Controller Kit

A simple 315MHz wireless controller kit consisting of a 4-button RF keyfob remote and a matching receiver module. No programming or microcontroller is required — power the receiver with 5V DC and press a button on the keyfob to activate the corresponding output pin.

Uses SC2273-L4 and SC2272-M4 encoder/decoder chips with AM (amplitude modulation). When a button is pressed, the corresponding receiver output goes HIGH; when released, it returns to LOW (momentary operation).

Key Features

• No Programming Required – Simple one-to-one link between keyfob and receiver
• 4 Independent Channels – Buttons A, B, C, D each activate a separate output pin
• Momentary Output – Output is HIGH while pressed, LOW when released
• 315MHz AM Modulation – SC2273/SC2272 encoder-decoder pair

Specifications
