Compact Arm/Linux IoT protocol conversion gateway has crypto chip

Sep 26, 2019 — by Eric Brown 2,063 views

Advantech has launched a rugged “WISE-710” IoT protocol gateway that runs Linux and its WISE-PaaS/EdgeLink stack on the i.MX6 DualLite and offers a crypto chip, 2x GbE, mini-PCIe, 3x serial/CAN, DIO, and optional analog and temperature interfaces.

Advantech previewed its WISE-710 gateway back in May and has now announced its release on Design World. The 100 x 70 x 36mm “industrial protocol gateway” runs Ubuntu 16.04 or the optional Yocto 2.1 on the tried-and-true NXP i.MX6 DualLite, which has shipped on earlier Advantech embedded computers such as its UBC-220.

The WISE-710 can optionally be loaded with Advantech’s WISE-PaaS/EdgeLink protocol-conversion software, which supports more than 200 communication protocols including Modbus, OPC-UA, MQTT, and IEC-60870-5-104 “to enable data collection from legacy devices,” says Advantech. WISE-PaaS/EdgeLink offers LWM2M client and Node ID technology and supports user-defined data acquisition periods for each input interface, “thereby reducing the volume of data transmitted and stored on the cloud.”

Another novelty here is a Microsoft Azure-certified Microchip ATECC508A secure element, which is also said to ensure compliance with Amazon AWS security regulations. The crypto chip offers embedded key encryption, authentication, and anti-tamper technology for IoT aggregation and prevents “unauthorized firmware updates and proliferation on the cloud,” says Advantech. (Coincidentally, we just covered a USB armory Mk II SBC that offers a very similar ATECC608A chip.)


The 1GHz, dual-core -A9 i.MX6 Dual is accompanied by 1GB DDR3, 8GB eMMC, and a microSD slot that supports data logger microSD cards. There are dual (non-native) GbE ports and a full-size mini-PCIe slot with optional WiFi, 3G/4G LTE (with SIM slot), and optional antennas. The announcement also mentions an optional NB-IoT wireless module, but it was not included in the accessory list.

The WISE-710 is further equipped with a micro-USB 2.0 host port plus RS232/485 and RS485/CAN serial ports and an internal RS485 interface. The system integrates isolated 4-in/4-out DIO with “wet contact & dry contact by switch,” as well as a modular interface that supports one of two additional options: 8x analog inputs with 4x digital inputs or 4x RTD (Resistance Temperature Detector) inputs with 4x thermocouple channels.

There’s a 24VDC terminal block input and low 5W typical power consumption, as well as -20 to 55°C support with 10 ~ 95% RH @ 40°C, non-condensing humidity resistance. You also get 2Grms vibration resistance per IEC 60068-2-64 and 10G shock resistance compliant with IEC 60068-2-27.

Multiple LEDs are included and you can choose from wall, DIN-rail, and pole-mount options. The detail view also shows a GND connection and a QR code interface.

Further information

The WISE-710 is available now at an undisclosed price. More information may be found on Advantech’s WISE-710 product page.
