1.0 RF Engine 26X Series OEM Modules Overview
The RF Engine 26X Series (Model Number RF26X) is an IEEE 802.15.4, low power,
highly-reliable solution to embedded wireless control and monitoring network needs that
require high data rates. The Model RF26X is pin-compatible with Digi International’s
XBee and XBee-PRO RF modules.
The RF26X 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 a range of up to 4,000 feet and power consumption as low as
0.37 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 RF26X is
approved as an FCC Part 15 unlicensed modular transmitter. The modules provide up
to 16 channels of operation in the ISM 2.4GHz frequency band. The RF26X contains
both a power amplifier for transmission and a low noise amplifier in the receive path for
extended range.
