The SNAP Engine Model RF220SU is an IEEE 802.15.4, lowpower, highly reliable solution for embedded wireless control and monitoring networks.

Description [Hide]

The RF220SU embeds Synapse’s SNAP OS, the industry’s first Internet-enabled, wireless mesh network operating system, into the Atmel ATmega128RFA1 single-chip AVR® microcontroller with an integrated transceiver that delivers up to 2Mbits/sec. This low-cost module can have current consumption under 390nA to enable a new generation of battery-driven systems.

The RF220SU also includes a Skyworks SE2431L front-end module, which provides a power amplifier and LNA for increased range. SNAP’s on-board Python interpreter provides for rapid application development and over-the-air programming. The modules provide up to 15 channels of operation in the ISM 2.4GHz frequency band.

By default, the SNAP operating system automatically forms a mesh network with other nodes immediately on receiving power. No further configuration is necessary. Multiple unrelated SNAP networks can exist within the same area through several configuration options.
