Pin and Instructions:
Pin (from left to right) and instructions:
Pin Name Function Description
1 ATAD data input pin
2 VCC power positive
3 GND power supply negative
The transmitter module has three external interfaces, one in English. “VCC” means the power supply positive, “ATAD” means input, “GND” means the power supply negative.
Note
1. Wireless Transmitter Module Wireless Transmitter Transmitter Panel 3-12V Universal Voltage
2. Such as pro-distant distance requirements, can be accessed by a quarter-wavelength antenna, generally 50 ohm single-core wire, the antenna length of 315M is about 23cm, 433M of about 17cm;
3. Antenna position on the module to receive the effect is also affected, the installation, the antenna as far as possible straight away from the shield, high pressure, and interference sources.
