Introduction

The RF220UF1 SNAP Engine consists of an SM220UF1 on a carrier board. It is an IEEE 802.15.4, low-power, highly reliable solution for embedded wireless control and monitoring networks that require high data rates. The RF220UF1 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 RF220UF1 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, while Atmel’s low-power RF single-chip design saves board space and lowers power consumption. 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 outlined in the SNAP User Guide.
