Introduction

The SNAP Engine Model SM220 series consists of the SM220UF1 part number. It is an IEEE 802.15.4, low-power, highly reliable solution for embedded wireless control and monitoring networks requiring high data rates. It 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 better enable battery-driven systems. The SM220 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 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.
