Jrifedptry 10Set 433M Super Regenerative Module Wireless Transmitter Module 433M Regenerative Module

The position of the antenna also affects the receiving effect of the module. When installing, the antenna should be as straight as possible, far away from the shield, high voltage, and interference source; Remarks The VCC voltage must be consistent with the working voltage of the module, and the power supply must be filtered; the antenna has a great influence on the receiving effect of the module, it is best to connect a 1/4-wavelength antenna, generally a 50-ohm single-core wire is used, and the length of the antenna is 433M About 17cm; the receiving frequency, decoding method and oscillation resistance should be matched with the emission during use.
