A basic 315MHz RF link kit consisting of a transmitter and receiver module pair. Commonly used for simple wireless remote control, data transmission, and sensor communication between microcontrollers. Works well with the Arduino VirtualWire library for easy integration.

The transmitter accepts 3–12V input — higher voltage provides greater transmitting power and range. ASK (Amplitude Shift Keying) modulation keeps the circuitry simple and affordable.
