IrDA PROTO Additional Board
The IrDA PROTO additional board is used for wireless communication carried out via infrared waves. This board includes an infrared
transceiver modul TFDU4101 used for serial communication with devices transferring data via infrared waves such as printers, fax
machines, notebooks, industrial devices, etc. The MCP2155 circuit provided on the board is used to convert data received from
the transceiver module and send it to the microcontroller for further processing. The IrDA PROTO board communicates with a
microcontroller via serial communication UART.
The IrDA PROTO additional board is connected with a amicrocontroller via a 1x8 male
connector. The TFDU4101 infrared transceiver module can send and receive data in the scope
of over 1m at a rate of up to 115.2kbit/s. The baud rate depends on the MCP2155 circuit and
position of jumpers B1 and B0. Refer to the table on the right.
Labels used in the table have the following meaning:
E - Jumper is placed (Enable)
D - Jumper is removed (Disable)
