The Universal Infrared (IR) Remote Control (White, 21-Key) is a compact handheld transmitter that sends standard 38kHz infrared signals to control Arduino, ESP32, and other microcontroller projects. Its white housing and colour-coded buttons make it a popular low-cost companion for IR receiver modules in DIY electronics.

Key features:

  • 21-Key Layout: Includes numeric keys 0-9 plus channel, volume, playback, and equalizer buttons for versatile project control.
  • 38kHz IR Transmission: Sends standard infrared codes compatible with common receiver modules such as the VS1838B and TL1838.
  • Coin Cell Powered: Runs on a single CR2025 button-cell battery for months of intermittent use.
  • Compact Handheld Size: Slim white body fits comfortably in the hand and is easy to mount inside a project enclosure.
  • Wide Compatibility: Works with Arduino, ESP8266, ESP32, and Raspberry Pi projects using standard IR remote libraries.
