RF412 922 MHz Spread-Spectrum Radio

The RF412 is a high-speed 900 MHz serial radio designed for unlicensed operation in Australia and New Zealand.

The RF412 is a 915 to 928 MHz frequency-hopping spread-spectrum radio with a configurable transmit-power output of 5 to 250 mW and software-selectable channel masking for improved RF interference immunity. This power-sipping, yet speedy, radio provides a cost-effective way to network dataloggers.
