This shield addes the IR transceiver to Raspberry Pi.
1. Infrared Receiver:
- Frequency: 38KHz
- Receiving distance: 18-20m
- Receiving angle: +/- 45 degree
2. Infrared Transmitter:
- Wavelength: 940nm
- Transmitting distance: 7-8m
3. Support dual infrared transmitter LEDs:
- It requires user to solder the infrared LED D2, and disconnet the solder point SJ1.
4. Support LIRC software
5. Support XBMC. Users can use the infrared functions under XBMC.
6. Support dual GPIO buttons, users can configure the functions of these two buttons.
The pin layout:
Works great with an additional LED

I added another LED to the shield and the range is about 8 meters. Without the additional LED, the range was about 2 meters. There are instructions out there to add the LED. It's pretty easy but does require soldering. Be careful. LEDs typically can take a maximum of three seconds of heat from a soldering iron before they are toasted.
Works great but no transmission distance.

The shield works perfectly for both transmit and receive, but the 7-8 meter distance on transmit is very, very misleading. I can get 2 meters, at best, under ideal conditions. And then only when the LED is pointed directly at the device being controlled. I'll try to solder in a second LED and see if things improve.
Worked like a champ!

I plugged it in, configured my LIRC, and it worked like a champ. I am able to complete my project now.
