ESP8266 Infrared Transmit Receive Module Type‑C Interface WiFi IR Transceiver Board For Smart Home Remote Control IoT Project

ESP8266 Infrared Transmission and Reception Module

📌 Product Overview The ESP8266 infrared transmit and receive module is a NEC instruction WIFI transparent transmission module built around the easy-to-develop ESP8266 (ESP-12F) wireless SoC chip. It integrates infrared transmitting and receiving circuits, supporting 38KHz infrared signal. After connecting to WIFI, it receives NEC-format remote control signals and transmits the data via UDP to another same module, which then re-sends the infrared signal, realizing cross-room infrared remote control forwarding. Equipped with Type-C power supply interface, it adopts web page network configuration for simple setup, suitable for smart home infrared signal repeater, embedded secondary development and DIY remote control extension projects. ✨ Core Features

1. Built-in ESP8266 ESP-12F low-power WIFI chip, supports 802.11b/g/n WIFI protocol.
2. Integrated IR transmitting diode and IR receiving head, realize infrared signal receiving and sending in one module.
3. Support NEC infrared signal decoding, UDP network transparent transmission, achieve cross-room infrared remote control relay.
4. 38KHz infrared carrier frequency, effective infrared transmit & receive distance up to 5 meters.
5. Web page hotspot distribution network, users can configure WIFI through mobile browser easily.
6. Short-circuit TX and RX pin while powering on to clear saved WIFI password for network reset.
7. Type-C interface for 5V power supply, reserved pin header leads for secondary development.
