Data module

Circuit Design's RF modules contain all the high frequency components required for transmitting data. All these components are shielded by the metal case.
Specific protocols are not incorporated. Your own original protocol can be used, but must follow the requirements of maximum pulse width.
Digital coding such as Manchester coding is recommended for meeting the maximum pulse requirement.
