This is a DIY Infrared Reversing Indicator kit parts. You should solder it by yourself.Transmitting audio signals through infrared signals.

1>.High sensitivity;
2>.Low power;
3>.Wide operating voltage range;
4>.Low power consumption;
5>.DIY design;


No. Parameter Value
1 Model TAI-01
2 Transmitter Operating Current Less than 15mA
3 Soldering Difficulty Level Easy
4 Working Voltage DC 4V-9V(Recommend 5V)
5 Output Power 2W(max) 8ohm
6 Communication Distance 50cm
7 Transmitter PCB Size 36.5*20mm
8 Receiver PCB Size 39.5*23mm

Working Principle:
1>.Transmitter: The audio signal is loaded into the infrared light-emitting diode through triode modulation, so that the light emitted by the infrared light contains an audio signal.;
2>.Receiver: The infrared receiving diode converts the infrared light containing the audio signal into a weak electric signal, and the audio signal is amplified by the audio amplifier to push the horn to restore the sound.

Step 1: Complete the installation in the normal way following installation manual and schematic.(Please request separately).
Step 2:Connect 2W 8ohm speaker(It does not include in package!) and input audio;
Step 3:Connect DC 4-9V voltage.
Step 4:Test and use.

Using Attention:
1>. Please make sure all components in right direction and right place.
2>. Please check whether pseudo/float welding.This is very important .
3>. The soldering iron can't touch the components for a long time, otherwise the components will be damaged because of the high temperature.
4>. It is recommended to use a stable power supply, otherwise it may interfere with the audio signal output.
5>. It uses the infrared principle, so it can't be used in the sun or in high temperature environment, otherwise it will easily interfere with signal communication.
