The module is based on the infrared transmitting module of the 940 infrared transmitting tube, and the infrared signal of the 940nm wavelength can be transmitted by a transmitting tube.Infrared receiving module (internal link)Get the signal and demodulation, with the coding and decoding process can achieve the remote control function.
Module features are as follows:
Control interface level, power supply can be 5V or 3.3V
High level driver, the required pull current is small
According to the actual application needs to manually adjust the direction of launch tube
4 M2 screw positioning holes, easy to install
