The IrDA 3 Click Board™ is an intelligent IR transceiver device that can send and receive UART commands via the IR interface. The IrDA 3 Click Board™ features both the IR transceiver and the encoder/decoder IC, used to convert the UART data and send or receive it in IrDA compatible format. IrDA 3 Click Board™ also has an onboard clock generator for the fastest possible UART performance of 115,200 bps, so it does not need an additional clock signal to be generated by the MCU.
