Advantech’s “UNO-1252G” is a rugged IoT gateway that runs Linux on an Intel Quark, and offers isolated serial and DIO ports, plus mini-PCIe expansion.

We’ve seen a variety of Internet of Things gateways that run Yocto Project Linux or Wind River’s Yocto-based Wind River IDP XT on Intel’s low-power (10W) Quark processor, and they’re all fairly distinctive. Like Advantech’s UBC-221, its new UNO-1252G is a less feature rich device than the Aaeon AIOT-X1000 or Adlink’s Matrix MXE-100i or top-of-the-line Matrix MXE-200i.

Like the Adlink models, the fanless UNO-1252G offers DIN-rail mounting, and has a wide-range power supply. It also similarly supports an extended temperature range (in this case, -20 to 60°C), and provides shock and vibration resistance.

The UNO-1252G is the only one of the bunch that offers isolation on its serial ports, in addition to DIO. It also offers chassis grounding support. Measuring only 105 x 100 x 63mm, the device is billed as Advantech’s smallest industrial computer to date. (The UBC-221 is smaller, but does not principally target heavy industrial settings.)

All this fits nicely with Advantech’s intended purpose for the device, as an industrial IoT aggregation gateway for sensor inputs from older endpoint equipment that lack wireless support. The UNO-1252G is designed to “connect legacy devices to the Internet of Things (IoT) without needing to replace the entire infrastructure,” and is “ideal for use in remote locations,” says the company.

Compared to the systems listed above, the UNO-1252G has the lowest RAM allotment, at 256MB, and it depends on a microSD slot instead of onboard or other storage options. Like the other models, the UNO-1252G offers USB ports and dual Fast Ethernet ports. The DIO, RS232/485, and RS232 ports are all isolated from power surges.

Unlike all but the Advantech UBC-221, the UNO-1252G offers two mini-PCIe slots instead of one. An external I/O panel supports one of Advantech’s mini-PCIe based iDoor modules, which have appeared in the company’s TPC-51WP and TPC-1551WP touch-panels. Specifically there’s support for GPRS, 3G, GPS, and WiFi iDoor modules, starting with the recently-introduced PCM-24S33G, which provides both 3.75G HSPA and GPS wireless capabilities. These options are supported with a SIM card slot, dual antenna connectors, and optional antennas.
