An RF (Radio Frequency) module is a small electronic circuit used to transmit and receive radio signals on various frequencies. These modules are integral to wireless communication systems, enabling devices to communicate without the need for physical connections. They come in various designs, such as through-hole and surface mount, and can support different types of networking topologies and protocols, including point-to-multipoint and mesh networks. RF modules are commonly used in applications requiring long-range, low-power, and secure communication solutions, and are designed to be easy to integrate into a wide range of devices and systems
