This compact 2-key infrared remote controller provides a simple ON/OFF wireless input for your projects. Using the standard NEC protocol at 38 kHz, it transmits reliably over 8 metres with a 60° beam angle — perfect for activating robots, toggling devices, or triggering actions from across the room.
With a little programming, the two buttons can be mapped to any commands — forward/backward, arm/disarm, or any pair of actions your project needs. Battery included.
