  • Description

    EMB-ZRF212B  is an 868 / 915 MHz wireless module that combines high performance to small dimensions and low cost, providing the system integrator a simple and easy way to add IEEE® 802.15.4 / ZigBee / Atmel® LightWeight Mesh 868 MHz wireless connectivity; in particular, mesh networking features provide high flexibility and reliability in over-the-air protocol development.

    Notable features include:

    • Integration with the latest Atmel®  AT86RF212B transceiver;
    • RF output power can be increased up to +10 dBm by firmware
    • RF sensitivity up to -110 dBm
    • Range up to 1000m (LoS)
    • Ready-to-use for Mesh, Peer-To-Peer and Point-to-Point network topologies
    • Provides easy-to-use self-healing mesh networking (thanks to  Atmel® LightWeight Mesh)
    • Tri-band module: 868 MHz (EU), 915 MHz (US and Japan) or 780 MHz (China)

    The EMB-ZRF212B modules ship programmed with EBI-802.15.4 which allows the customer to use the modules as a simple, ready-to-use modem (using AT-like commands over UART; see EBI protocol page for more information). The evaluation kit EMB-ZRF212B-EVK is strongly suggested to customers willing to develop their own firmware applications, since the kit provides all hardware tools required to download a custom firmware on the module.
