315MHz RF Transmitter and Receiver Module Link Kit for Arduino / ARM / MCU / Raspberry Pi Built for quick, lowcost wireless links between controllers and remote sensors or actuators. This kit includes both a 315 MHz transmitter module and a matching receiver module, providing a simple way to add wireless communication to Arduino, ARM boards, microcontrollers (MCU) and Raspberry Pi projects. Why you need it Rapid prototyping: Add wireless control or data telemetry without complex RF design. Broad compatibility: Works with common development boards and microcontrollers so you can reuse existing code and hardware. Dualmodule kit: Includes both transmitter and receiver so you can build a complete link straight away. Key benefits Easy to integrate: Simple digital interface that ties directly into GPIO or serialstyle data pins on Arduino, ARM, MCU and Raspberry Pi platforms. Costeffective: A practical solution for testing wireless ideas and creating small DIY systems without expensive radios. Flexible: Suitable for remote control, simple telemetry, wireless triggering and basic IoT links. Main features and attributes Frequency: 315 MHz operation for standard lowpower wireless links. Kit contents: Matched transmitter and receiver modules for building a complete link. Functionality: Transmit and receive digital data between two points; ideal for remote on/off, sensor reporting and basic command transmission. Compatibility: Designed to interface with Arduino, ARM development boards, generic MCUs and Raspberry Pi GPIO. Form factor and material: Compact PCBmounted modules that are lightweight and easy to mount; includes antenna connection points for improved range. Performance: Provides a reliable wireless channel for short to mediumrange applications; actual range depends on antenna, environment and power configuration. How it solves common problems Eliminates wiring: long or inconvenient wires with a wireless link to simplify installations or prototypes. Speeds development: Focus on application logic rather than RF design; use available libraries and common wiring patterns. Low barrier to entry: No specialized RF knowledge required to get a working link for most simple use cases. Typical applications and use cases Home automation and remote control: Switch relays, control lights, gates or other devices from a remote controller or central hub. Wireless sensor links: Send temperature, motion, or door/window sensor data back to an Arduino or Raspberry Pi for logging and automation. Prototyping and education: Teach or learn wireless communication basics, experiment with digital remote control and create proofofconcept projects quickly. Integration tips Connect the transmitter data pin to a digital output and the receiver data pin to a digital input on your board; use simple encoding or existing libraries for reliable communication. Antenna and placement matter: Use the recommended antenna and mount modules away from large metal objects to improve range and stability. Power and logic levels: Match module supply and logic levels to your controller or use appropriate level shifting if required. What you get A matched 315 MHz transmitter and receiver module pair ready for use with Arduino, ARM, MCU and Raspberry Pi platforms. A practical, lowcost RF solution for adding wireless capability to projects and prototypes. this link kit when you want a straightforward, reusable way to add wireless communication to embedded projects without investing in complex radio hardware or design.
