Highly integrated infrared decoding and encoding serial communication module designed for microcontrollers. Utilizes TTL-level serial communication with default 9600 bps and supports 4800/19200/57600 bps. Fully supports NEC-format infrared protocols, covering 99% of household appliances like TVs, set-top boxes, and fans. Transmission and reception range of approximately 6-10 meters, affected by ambient light. Operating voltage of 3V to 5.5V DC, with a peak transmission current of up to 100mA. ICSF002A is a highly integrated infrared decoding and encoding serial communication module designed to simplify infrared remote control signal processing for microcontrollers. The module typically provides 4 pins: VCC for power supply positive terminal (3.3V-5V), GND for power supply ground, TXD for module serial port transmit pin (outputs decoded data to the microcontroller), and RXD for module serial port receive pin (receives encoded commands from the microcontroller and converts them to infrared transmission). Color: As Shown Material: PCB Package Contents: 1*module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
