Tiny Linux-ready ARM9 module targets secure IoT

Aug 7, 2014 — by Eric Brown 2,261 views

Lantronix launched an IoT-oriented “PremierWave SE1000” module with an ARM9 CPU, Fast Ethernet, a CGI-ready web server, security features, and a Linux SDK.

The PremierWave SE1000 computer-on-module is intended for developing Internet of Things (IoT) applications with Ethernet and IPv6 requirements. The COM integrates an IPv6-ready TCP/IP stack, as well as a CGI-capable web server that “transforms a standalone device into a networked product that can be managed remotely via a standard web browser,” says Lantronix. Users can remotely monitor and collect information from the device in real-time and send it to dynamic web pages, says the company.

The module ships with a security stack that includes end-to-end SSL, TLS, and SSH tunneling, as well as FIPS 140-2 cryptography. A Lantronix applications suite is included, featuring tunneling, secure tunneling, configuration, and web configuration tools.

The tiny (55 x 30mm) module is equipped with a Lantronix ARM9 processor clocked to 400MHz, plus 64MB of RAM. You can choose between 64MB and 256MB of onboard flash, and a 10/100 Ethernet interface is backed up with full protocol support.

Additional onboard I/O available via an 80-pin connector includes a USB 2.0 host and device port, dual serial ports, and SPI, CMOS, and I2C interfaces. The module supports industrial temperatures, and is is touted for offering low power consumption modes.


The PremierWave SE1000 ships with a Linux SDK developed by Timesys. The stack includes U-Boot, a cross-development environment, and open source GNU C/C++ tool chain.

Development kit for the PremiereWave module

The PremierWave SE1000 can use the development kit available for the similar PremierWave EN module (see farther below). The modular development board provides options including Ethernet, WiFi, and ultra-secure WiFi, supported with an antenna. A power supply and various cables are also provided.
