ETRX358USB
Zigbee & Thread Compatible Radio for IoT Applications
In a USB Stick Form Factor
The ETRX358USB is a USB-compliant device
peripheral designed to enable USB host devices
to connect to the Internet of Things over
802.15.4 Networks. The in-field upgradeable
firmware allows interaction with either ZigBee
®
or THREAD wireless mesh networks.
Featuring the Telegesis™ ETRX3588 wireless
mesh networking module (based on the
EM3588 System-on-Chip (SOC) from Silicon
Labs Inc.), the ETRX358USB takes advantage of
a powerful 32-bit ARM
®
processor with 512 kB
of flash memory and 64 kB of RAM. A link
budget of up to 110 dB is ideal for typical
ZigBee and THREAD applications.
The devices make use of the standard USB
communication device class (CDC) allowing the
best possible native driver support across a
wide range of operating systems.
