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.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- 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.
