Product description: nRF905 433 / 868 / 915 MHz radio module - THT transceiver with antenna
Radio module (transmitter and receiver) operating in 433 MHz, 868 MHz and 915 MHz band with SPI communication interface. It is powered by2.7 V - 3.3 V.The devicehas an external antenna which is connected to the SMA connector, the signals are led to the goldpin connectors.
Since the device works with voltage up to 3.3 V, in order to connect with boards operating on 5 V (e.g.Arduino Uno) it is necessary to usea converter.
