IrDA (Infrared Data Association) transceiver modules are devices that integrate an infrared emitter, photodiode, and control circuitry for wireless data transmission. These modules typically comply with IrDA standards, supporting specific data rates such as 115.2 kbit/s (Standard Infrared SIR mode). They are widely used in portable devices and various applications requiring wireless data transmission, characterized by low power consumption, a range of operating voltages, and various packaging options.
