| | i.MX8M-Driven Pico-ITX SBC Features Dual-DSP Audio Module
Estone is launching an "EMB-2238" Pico-ITX board for audio and voice control applications that runs Linux on an i.MX8M and offers a dual-DSP audio hub and DAC, 40-pin GPIO, and optional PoE and second GbE. Toledo, Ohio based Estone Technology (known for its former Habey brand) offers a variety of Linux-friendly Pico-ITX boards, including boards based on the i.MX6 ( EMB-2230), i.MX6 UL ( EMB2200) models and Intel Cherry Trail EMB-2610. The company recently announced (via Electronics Weekly) an EMB-2238 board with the same 100 mm x 72 mm form factor. The SBC builds on the audio strengths of NXP's i.MX8M SoC with the help of high-end audio circuitry from Cirrus Logic.
The EMB-2238 uses the quad-core version of the 1.5 GHz, Cortex-A53 equipped i.MX8M, which also includes a GPU and 266 MHz Cortex-M4 chip. Estone provides a Yocto Project stack based on Linux kernel 4.9, Qt and Wayland. It also supports Android 8.1.0.
Rugged Touch Panel Computer Targets Railway System Designs
ADLINK Technology has released its latest Driver Machine Interface (DMI) touch panel computer, the DMI-1210, designed specifically for train control and driver information display. Powered by the Intel Atom x5-E3930 processor (formerly Apollo Lake) and featuring a 12.1" (4:3) high resolution color display, 5-wire resistive touch screen and securable I/O interface, the DMI-1210 can be deployed as an HMI unit for driver's desks, control panel for passenger information systems, surveillance system control/display unit or in railway diagnostics and communications applications.
The DMI-1210 is an EN 50155 certificated, cost-effective, commercial-off-the-shelf (COTS) driver interface that offers train radio display, electronic timetable and diagnostic display functions and additional functionality such as train data recorder. The DMI-1210 supports full range DC power input from +16.8 V to +137.5 V DC. Optional MVB, GNSS, 3G/LTE, WLAN and Bluetooth through add-on modules give system integrators the necessary tools to expand use case possibilities.

i.MX6-Based SBC Offers Global Cellular Expansion VersaLogic has announced the Swordtail SBC that features models with either the NXP i.MX6 Quad (quad core), or the i.MX6 DualLite (dual core) processors. The SBC includes on-board Wi-Fi, Bluetooth and a cellular plug-in socket. At home in hostile environments the compact 95 mm x 95 mm computer board is rated for operation at full industrial temperature range (-40° to +85°C). Unlike many Arm-based "modules", VersaLogic's new Arm-based products are complete board-level computers. They do not  require additional carrier cards, companion boards, connector break-out boards or other add-ons to function. Swordtail boards have been designed to enable transmission of maintenance or diagnostic information without the need for a wired connection. Wi-Fi and Bluetooth radios are included on board and a NimbleLink Skywire socket supports a wide range of optional cellular and other wireless plug-ins. The Swordtail embedded computer board is suited for deployment into demanding industrial, smart city and transportation applications requiring rugged, long-life, power efficient and industrial temperature rated solutions. |
