Introduction

nRF905 is a single chip radio transceiver for the 433/868/915MHz ISM band. The transceiver consists of a fully integrated frequency synthesizer, receiver chain with demodulator, a power amplifier, a crystal oscillator and, a modulator. The ShockBurst™ feature automatically handles preamble and CRC. You can easily configure the nRF905 through the SPI. Current consumption is very low, in transmit only 9mA at an output power of -10dBm, and in receive mode 12.5mA. Built-in power down modes makes power saving easily realizable.
