This electronic infrared adapter serial transceiver circuit is based on a TFDS4500 IC and can be used to transmit data from portable devices to a PC using IR and serial port. TFD4500 infrared adapter it`s a low power infrared transceiver modules for serial infrared (SIR) data communication which support IrDA speeds up to 115. 2 kbit/s. In this i
nfrared circuit transceiver it`s integrated an photo diode infrared emitter (IRED) and a low power analog control IC.
