What is RF-Modules?

RF modules, short for radio frequency modules, are electronic components used for wireless communication. They typically consist of a transmitter and a receiver that operate on radio frequencies to transmit and receive data or signals wirelessly. RF modules are commonly used in applications such as remote controls, wireless data transmission, wireless alarms, and various types of telemetry systems. They can operate on different frequencies, including popular bands like 433MHz, 868MHz, and 2.4GHz, depending on the application requirements.

What are RF Modules?

RF modules, short for Radio Frequency modules, are compact electronic devices that facilitate wireless communication by transmitting and receiving data over radio frequencies.
