Compact embedded system runs Linux on i.MX8M

Nov 25, 2020 — by Eric Brown — 4202 views

MiTac’s fanless “ME1-108T” embedded computer runs Linux on an up to quad-core i.MX8M with up to 4GB LPDDR4, up to 32GB eMMC, 2x GbE, 3x USB, and HDMI, DP, serial, mini-PCIe, and 40-pin RPi GPIO.

ICP Germany announced the launch of MiTac’s compact ME1-108T embedded system. Although we have reported on dozens of compute modules and SBCs that run Linux on NXP’s dual- or quad-core, Cortex-A53 i.MX8M, the ME1-108T appears to be only the second embedded system using the SoC after Axiomtek’s Agent336.

[Update: It turns out the ME1-108T is based on MiTac’s ND108T Pico-ITX SBC, which we covered in the ICP Germany version of the SBC.]

Note that many SBC vendors offer chassis options, and MNT Research launched a MNT Reform laptop based on the i.MX8M. There are also IoT gateways based on the similar i.MX8M Mini, including Compulab’s SBC-IOT-iMX8 and Eurotech’s ReliaGate 10-14.

MiTac, which last month launched a larger, Intel Coffee Lake based MX1-10FEP system, ships the ME1-108T with either the dual- or quad-core i.MX8M clocked at up to 1.3GHz. The i.MX8M integrates a Cortex-M4 MCU and a Vivante GC7000 Lite GPU. Unlike most of the i.MX8 family SoCs, the i.MX8M offers 4K video support. MiTac supplies a BSP with Yocto Sumo and Android 9 Pie, both with Linux Kernel 4.14.98.

The fanless, 140 x 100 x 38.75mm is even smaller than the compact Agent336, but it lacks the Axiomtek system’s more extensive ruggedization features. The sheet-metal enclosed system has a 0 to 55°C operating range with 10% ~ 90% non-condensing relative humidity resistance.

The ME1-108T is available with 1GB to 4GB of 800MHz LPDDR4 and optional 8GB to 32GB eMMC. A microSD slot integrates a SIM card slot for use with the full-size mini-PCIe slot for cellular expansion. Dual SMA antennas are available for optional WiFi and Bluetooth.

Dual GbE ports (Realtek RTL8111H and RTL8211FD) are joined by 2x USB 3.0 and single USB 2.0 and RS232/422/485 COM ports. A 40-pin Raspberry Pi compatible GPIO header is available internally and is extended externally via a 10-pin terminal block with 4-in/4-out GPIO, 5V, GND, and terminal.

Media features include a 4K-ready HDMI 2.0 port and an HD-ready DisplayPort 1.2. Realtek ALC5660 audio is available, but we saw no external jack.

The two dual-core SKUs differ in that they remove the DP and COM ports along with one of the two GbE ports. The dual-core ME1-8MD-1G8G SKU offers 1GB RAM and 8GB eMMC while the dual-core ME1-8MD-2G16G gives you 2GB and 16GB. The quad-core ME1-8MD-4G32G SKU has 4GB and 32GB and the full array of ports.

The 12V/3A terminal block input connects to a 12V, 36W adapter. There is also a power button and LED, as well as VESA and wall mounting.

 
Further information

The ME1-108T is available with undisclosed pricing in dual-core ME1-8MD-1G8G and ME1-8MD-2G16G models and a quad-core ME1-8MD-4G32G SKU. More information may be found in ICP Germany’s announcement and order page and on MiTac’s product page.
