{"title":"IR Remote Controller (2-Key)","handle":"ir-remote-controller-2-key","url":"/products/ir-remote-controller-2-key","description":"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.\n\nWith 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.\n\nKey Features\n\n\n2-Key Design – Simple ON and OFF buttons\n\nNEC Protocol – Standard IR encoding (address 0x00FF, ON: 0x02, OFF: 0x98)\n\n38 kHz Frequency – Compatible with common IR receivers\n\n8+ Metre Range – Reliable transmission at 60° angle\n\nUltra-Low Power – 3–5 μA quiescent, 3–5 mA active\n\nBattery Included – CR2025 coin cell pre-installed\n\n\nSpecifications\n\n\nProtocol: NEC (address 0x00FF)\n\nButtons: ON (0x02), OFF (0x98)\n\nFrequency: 38 kHz\n\nRange: >8 m\n\nBeam Angle: 60°\n\nBattery: CR2025 coin cell (included)\n\nCurrent: 3–5 μA (quiescent) / 3–5 mA (active)\n\nDimensions: 86 × 40 × 6 mm\n\n\nIdeal For\n\nRobot remote control (on/off, forward/backward)\nArduino and microcontroller IR projects\nWireless device activation and toggling\nLearning about IR communication protocols\n\n\nPackage Contents\n\n1× IR Remote Controller (2-Key) with CR2025 battery\n\n\nResources\n\nNEC IR Protocol Reference\n","vendor":"DFRobot","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":12063,"title":"Default Title","sku":"DF-FIT0389","price":2.41,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
