IrDA interface for your mainboard

Many modern main boards have an IrDA connector on board, but the required transceiver is often missing. if you can't find the exactly fitting module for your main board, you can probably use a module from another main board if you connect it in the right way. just see the main board documentations (or search the web) and compare the pinouts. irda modules normally need 4 signals: gnd, +5v, rxd and txd.

or you can build your own IrDA module! All you need is a IrDA transceiver and some resistors and capacitors.

There is also a Silicon Chip Australia project on the same topic, using the same components. Their PCB layout surely looks better too.

Have fun building it.
