This is new ultra-thin 38KHz universal infrared IR Remote Control with Battery, NEC encoding format 1-21-key remote control, USB port stereo, car MP3, foot bath, lighting, digital photo frame, microcontroller development board, learning board, etc.

This is a precision 38 kHz Infrared transmitter uses a MOS integrated circuit with NEC transmission format ideally suited for remote operation in TV, VCD, and all compatible IR receiver devices. The NEC transmission format includes leader codes, customs codes (16 bits), and data codes (16 bits). The frequency of oscillation is determined by the Crystal. The IR LEDs connected to the output emits IR pulses at 38kHz.The circuit is ideal for most IR Sensors since these are designed for 38 kHz pulsed IR rays.
