The 433 MHz RF Transmitter & Receiver Pair is a basic ASK-type wireless communication kit that operates at battery-friendly voltages (~3–12 V). It enables low-speed wireless data transmission over short to moderate ranges (50–100 m line-of-sight). The pair includes a small 4-pin transmitter board and an 8-pin super-regenerative receiver board. Ideal for DIY home automation, remote control, sensor modules, and basic wireless projects using Arduino or Raspberry Pi.
