IR LED
This works well when the exposed LED of the remote is aligned with the LED on the IR widget. Remotes that have a window over the LED can be difficult to capture reliably.
Two trace cuts and two jumpers are required if the PCB is used.
The wiring is a bit different than when using a QSE157 because the comparator in the PIC is used to detect the low voltage from the LED.
Different firmware is required to enable the comparator.
IrDA
An IrDA module was salvaged from an old PDA. The circuit board was cut around the module and the capacitor that was connected to the power pins of the module. The small chunk of PCB was glued to the IR Widget PCB and wires used to connect the two circuit boards.
This works very well!
