SNAP Engine RF220SU Module Overview
The SNAP Engine Model RF220SU is an IEEE 802.15.4, low-power,
highly reliable solution for embedded wireless control and monitoring
networks.
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 LNAfor 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 SNAPoperating system automatically forms a mesh network with other nodes immediately on
receiving power. No further configuration is necessary. Multiple unrelated SNAPnetworks can exist within the same
area through several configuration options outlined in the SNAPUser Guide available from www.synapse-
wireless.com.
NOTE: Channel 15 is receive-only due to FCCpower restrictions.
