1.0 RF Engine Model SM200

OEM Modules Overview

The RF Engine Model SM200 includes the SM200P81 and RF200P81 part numbers.

They are IEEE 802.15.4, low power, highly-reliable solutions to embedded wireless

control and monitoring network needs that require high data rates. The Model SM200

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. These low-

cost modules can have power consumption as low as 0.25 µA to enable a new

generation of battery-driven systems.

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 the overall Bill of Materials and power consumption. The Model

SM200 modules are approved as an FCC Part 15 unlicensed modular transmitters. The

modules provide up to 16 channels of operation in the ISM 2.4GHz frequency band.
