It is listed for sending and receiving commands in NEC format, allowing a compatible microcontroller or development board to communicate with supported infrared remote-control devices.<\/p>\n<h4>\ud83d\udd27 Listed specifications<\/h4>\n<ul>\n<li>Supply voltage: 5 V<\/li>\n<li>Communication: serial\/UART, TTL logic level<\/li>\n<li>Supported format: NEC and listed compatible encoder families<\/li>\n<li>Listed operating distance: approximately 6\u201310 m; actual range varies with orientation, obstacles, ambient light, transmitter\/receiver alignment and the target device<\/li>\n<li>Board dimensions: 27 \u00d7 17 mm<\/li>\n<li>Functions: infrared transmit and receive, NEC-format encoding\/decoding, and an expansion interface for an IR transmitter<\/li>\n<\/ul>\n<h4>\ud83d\udd04 Listed compatible encoder IC families<\/h4>\n<p>The listing names uPD6121, uPD6122, TC9012, PT2221, PT2222, SC6121, SC6122 and SC9012. Compatibility with a specific remote depends on its protocol variant, command format and the module firmware; the list does not mean that every infrared appliance is supported.<\/p>\n<h4>\u2699\ufe0f How to use<\/h4>\n<p>Connect the module to a regulated 5 V supply and the controller\u2019s serial interface, observing the board\u2019s pin labels and common ground. Confirm the UART pinout, baud rate and signal voltage from the documentation or markings for the supplied board before connecting it directly to a microcontroller. Learn or transmit the command format supported by the target device, then test the setup at short range before relying on it.<\/p>\n<p>Infrared generally requires a clear optical path. Sunlight, bright lighting, obstacles, receiver angle, the remote\u2019s carrier and the target device can affect operation. The listed 6\u201310 m figure is a seller-stated range, not a guaranteed distance in every environment.<\/p>\n<p><strong>Compatibility note:<\/strong> \u201cNEC\u201d is a protocol family, not a guarantee of universal control. Air conditioners and other devices may use extended or vendor-specific frames even when their remote appears NEC-compatible.<\/p>\n<h4>\ud83d\udca1 Example applications<\/h4>\n<ul>\n<li>Microcontroller-based infrared remote-control prototypes<\/li>\n<li>Sending commands to compatible TVs, fans and other consumer devices<\/li>\n<li>Receiving and decoding compatible remote commands<\/li>\n<li>Simple short-range infrared data and control experiments<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Compact infrared transmitter\/receiver module with NEC-format encoding and TTL-level serial communication.
