Overview:  The module has a wide operating voltage range (DC5V-12V), high transmission power, low power consumption, and can be directly applied with a coding IC.  The data code and address code can be directly jumped, which is convenient and widely used in simple data wireless transmission, anti-theft alarm and other occasions.     Instructions for use:  The module has led two wires, which are connected to the positive and negative poles of the power supply, and the voltage is DC5-12V. Each launch can be realized directly by controlling the on/off of the power supply, and the time is not more than 5 seconds. A0~A7 is the 8-bit address code setting area, and the left side D0~D3 is the four-digit data code setting area. The cap sets the coding and data bits, and the antenna is connected (the multi-strand copper wire is about 23CM).     Specification:  Working voltage: 5-12V.  Emission current: 10mA.  Transmission frequency: 433MHZ.  Shooting distance: 200 meters (empty, receiving sensitivity -110dB).  Size: 38.2*19.5*8.7mm.  Coding method: Jumper cap interpolation.  Oscillation resistance: 4.7M.  Package includes:  5 x Wireless Transmitter Module
