RFM73-D 2.4 GHz radio module

Description

RFM73 is a GFSK transceiver operating in the ISM frequency range 2400-2483.5 MHz. Powered by a voltage of 1.9-3.6 V, the pins are goldpin connectors. It has a built-in PCB antenna. Transmission in series mode and data rates up to 2 Mbps make them suitable for applications requiring very low energy consumption. Built-in package processing engines enable their full operation with a very simple MCU as a radio system. Automatic re-transmission and automatic confirmation ensure a reliable connection without any disturbance to the MCU. RFM73 operates in TDD mode, both as a transmitter and as a receiver.
