This is a special infrared control expansion board for Raspberry Pi. Users can use the Raspberry Pi 2B/B+ expansion board to complete various infrared remote control and remote control functions. Some simple application scenarios: 1. Remote turntable machine: You can record the remote control function of the electrical appliance through the expansion board, and then remotely control the Raspberry Pi to emit infrared to control the electrical appliance. 2. Timing switch electrical appliances: through the expansion board can achieve timing to switch electrical appliances 3. Remote control car, you can remotely control Raspberry Pi car through infrared remote control 4. Audio and video playback control, XBMC, MPLAYER, etc. Function Description: 1. Infrared receiving function Working frequency: 38K HZ Receiving distance: 18-20m Receiving angle: +/-45 degrees 2. Infrared emission function Wavelength: 940nm Launch distance: 7-8m 3. Support infrared dual LED emission, the emission effect is stronger (the user needs to weld the spare emission tube D2 by himself, and disconnect SJ1) 4. Supports powerful LIRC software. Using LIRC and expansion boards, users can almost copy all infrared remote control functions (remote control for TV, amplifier, DVD, etc.), and control your various electrical equipment through commands . 5. Support XBMC system, users can use the infrared function of expansion board in XBMC environment 6. Support dual GPIO buttons, users can configure button functions through programming See more

IR infrared control expansion board can receive and launch, DIY dual IR launch, stronger effect. User can program the key function and support installing dual IR transmitter (need to install the extra transmitter and disconnect the SJ1). Working Frequency: 38KHz Transmitting Distance: 7-8m Receiving Distance: 18-20m. As a timing switch of the device; Remote control Raspberry Pi car; Remote to play the video or music; Control your home appliances by IR. designed for RPi 3 B+ / 3B / 2B / B+. You can remote control or be controlled by the Infrared remote function.
