CompuLab’s rugged “CL-SOM-iMX8X” module runs Linux on a quad -A35 i.MX8X and gives as much as 4GB LPDDR4 and 64GB eMMC, as much as 2x GbE, and non-compulsory 802.11ac/BT Four.2. There’s additionally a $395 eval package.

CompuLab, which has beforehand launched NXP i.MX8M-based CL-SOM-iMX8 and that i.MX8M Mini based mostly UCM-iMX8M-Mini modules, has now returned with a module that helps the i.MX8X. Just like the CL-SOM-iMX8, the brand new CL-SOM-iMX8X is a SODIMM-style module. It’s designed for industrial HMI, constructing management, picture processing methods, IoT gateways, medical units, and metering methods.

NXP’s power-efficient, Cortex-A35 based mostly i.MX8X is clocked to 1.2GHz and features a 266MHz Cortex-M4 chip and a Tensilica HiFi Four DSP. CompuLab is providing solely the quad-core i.MX8X QuadXPlus somewhat than the dual-core fashions. It’s accessible with or with no Four-shader Vivante GT7000Lite GPU.

Different i.MX8X-based modules embody Kontron’s SMARC-sAMX8X, Congatec’s Qseven-based Conga-QMX8X, F&S’ efus MX8X, Phytec’s phyCORE-i.MX 8X, Variscite’s VAR-SOM-MX8X, and the Toradex Colibri iMX8X and Digi ConnectCore 8X.

The CL-SOM-iMX8X is on the market with 1GB to 4GB LPDDR4 and 4GB to 64GB eMMC. CompuLab will optionally preload a downloadable Linux BSP with ready-to-run photos. It consists of mainline Linux kernel Four.14, a Yocto Challenge SDK, the U-Boot bootloader, and an RTOS BSP for the MCU.

As normal with CompuLab, there are plenty of choices, and pricing is detailed in an internet configurator. You should purchase it with or with no licensed wi-fi module with 802.11ac and Bluetooth Four.2, which makes use of up your sole PCIe Gen three.Zero interface. You too can select between one, two, or no Gigabit Ethernet controllers in any respect.

Even the USB interfaces are a la carte. A USB 2.Zero OTG interface is customary, and if you happen to haven’t already used up the PCIe connection for wi-fi, you should use it so as to add a USB 2.Zero host interface. For less than $2 extra, you possibly can add a USB hub with three extra USB 2.Zero host interfaces. Further I/O consists of as much as 4x UARTs, 3x CAN-FD, 4x SPI, 3x I2C, 4x PWM, 5x ADC, and 96x GPIOs.

If you are going to buy the usual i.MX8X mannequin with GPU, you possibly can drive twin impartial shows by way of 2x MIPI-DSI (Four-lane) and 2x single/twin channel LVDS, each at as much as 1080p decision with capacitive contact help. Different media options embody Four-lane MIPI-CSI, S/PDIF audio I/O, and “as much as” 1x I2S/SAI digital audio.

The 68 x 38 x 5mm, 14-gram module is additional geared up with an RTC, a JTAG debug interface, and a Four.0V to Four.5V enter that delivers three.3V I/O voltage. Ruggedization options embody a selection between Zero to 70°C, -20 to 70°C, and -40 to 85°C temperature ranges, in addition to customary 10% to 90% humidity, 50G/20ms shock, and 20G, Zero-600Hz vibration resistance.

EVAL-iMX8X analysis package

The CL-SOM-iMX8X is supported with an EVAL-iMX8X analysis package constructed round an SB-iMX8X service board. The 160 x 136 x 22mm SB-iMX8X board is provided with 2x GbE, 2x USB 2.Zero host, and micro-USB OTG and debug ports.

There’s a mixed MIPI-DSI/LVDS header and a MIPI-DSI FPC connector with capacitive contact that helps an non-compulsory, 5-inch LCD panel. The CSI connector helps an non-compulsory digicam module.

The SB-iMX8X board is additional geared up with full-size mini-PCIe and SD slots and varied I/O headers. There’s an Eight-18V enter and the identical ruggedization options discovered on the CL-SOM-iMX8X module.

The EVAL-iMX8X package consists of WiFi antennas, USB and MIPI-DSI to HDMI adapters, a 12V energy provide, and varied cables. You additionally get a 12-month technical help contract, schematics, invoice of supplies, and structure recordsdata for the service board.

Additional data

The CL-SOM-iMX8X module begins at $73 for 1K quantity orders, and the EVAL-iMX8X analysis package is on the market for $395, together with the module. Extra data could also be present in CompuLab’s CL-SOM-iMX8X announcement and product web page, in addition to the SB-iMX8X (EVAL-iMX8X) product web page.
