Tiny wireless gateway runs Linux on an i.MX6 ULL

Mar 27, 2019 — by Eric Brown 1,082 views

Artila’s 112 x 89 x 30mm “Wireless Gateway Matrix-750” runs Linux on a Cortex-A7-based i.MX6 ULL, and offers 2x LAN ports plus USB OTG, serial, DIO, and mini-PCIe with micro-SIM and antennas.

Artila has announced a new Matrix wireless gateway that offers a faster processor and much smaller footprint than recent models but with more limited features. The Wireless Gateway Matrix-750 runs Linux 4.19x on NXP’s 800MHz, Cortex-A7 based i.MX6 ULL, which is faster than the 536MHz, Cortex-A5 Microchip/Atmel ATSAMA5D35 that powered its previous Matrix-710 and Matrix-713 gateways. The Matrix-750 is also more affordable: WDL Systems sells the Matrix-710 for $493 and the Matrix-713 for $486, and offers the Matrix-750 complete with an optional LTE modem for $383.

The wall- and DIN-rail mountable Matrix-750 measures a wee 112 x 89 x 30mm, weighs only 350 grams, and supports a 0 to 70°C operating range that could be considered “extended” at higher temperatures. Power consumption is only a smidge higher than the 710 and 713 models: 12V@250mA vs 12V@230mA. The system is designed for space-constrained, cost-effective remote monitoring solutions. Applications include transit, port, or mining, as well as “AGV,” which may stand for automated guided vehicles.

The Matrix-750 ships with 512MB LvDDR3, but instead of eMMC storage, you get a microSD slot that supports up to 128GB. There are dual 10/100 Ethernet ports rather than the previous combo of Fast and GbE ports, as well as a single mini-PCIe slot accompanied by a micro-SIM slot and 2x SMA slots. Accessories include WiFi and 4G/LTE mini-PCIe modem cards with dual external antennas.

The Matrix-750 provides single micro-USB 2.0 OTG and RS-485/RS-232 ports. There are also 2x isolated digital inputs, 2x solid-state relay digital outputs, and an internal serial debug port. Other features include a watchdog, LEDs, and an RTC with supercap backup. The system provides a 9-48VDC terminal block input with an optional 110-240VAC to 12VDC adapter.

The Linux stack includes kernel 4.19.x, U-Boot, a choice of file systems, and gcc 8.2.0 + glibc 2.28 toolchain. Other features include web servers, databases, script languages, text editor, and package management.
