1. NEC Directive WIFI Transmissive Module with easy-to-develop ESP8266 module. 2. ESP8266 is a high-performance wireless SoC that provides maximum utility at minimum cost, offering unlimited possibilities for Wi-Fi functionality to be embedded in other systems. 3. ESP-12F ESP8266 is a low-power WiFi module developed based on ESP8266, which can be easily developed twice. 4. This module has infrared transmission and reception function, which is highly functional. 5. The infrared transmitter-receiver distance is about 5 metres, and after connecting to wifi, the received remote control signal in NEC format can be transmitted to another device via UDP, and then sent out by another device, to achieve the effect of infrared transmission across the room.
