A simple 4-channel 315 MHz RF receiver module with toggle-type output. No programming, configuration, or microcontroller needed — just power it with ~5V DC and pair it with a matching RF keyfob remote. Each of the four buttons toggles its corresponding output pin on and off.
The toggle (T4) type works like a flip switch: press button A once to turn the pin high, press it again to turn it low. This makes it ideal for on/off control of lights, relays, and other loads.
Key Features
- Toggle Output – Press once to turn on, press again to turn off
- 4 Channels – Four independent outputs, one per remote button
- No Programming Required – Simple one-to-one link with matching keyfob
- No Microcontroller Needed – Standalone wireless control
Receiver Types Explained
- T4 (Toggle) – Press to turn on, press again to turn off (this product)
- M4 (Momentary) – Output is high only while the button is held down
- L4 (Latch) – Only one output active at a time; pressing a new button switches to that channel
Specifications
- Frequency – 315 MHz
- Type – T4 (toggle)
- Power Supply – ~5V DC
- Channels – 4
Ideal For
- Wireless on/off control for lights and relays
- Remote-controlled enclosures and projects
- Simple home automation without programming
Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
