The Seco SM-218 and Adlink LEC-IMX8MP SMARC 2.1 modules run Linux or Android on NXP’s i.MX8M Plus AI compatible system with up to 8 GB RAM, 64 GB eMMC, Dual GbE, PCIe Gen3 and optionally -40 to 85°C.
The first two SMARC 2.1 form factor modules with the NXP i.MX8M Plus SoC have been released, combining several other i.MX8M Plus modules, including Variscite’s VAR-SOM-MX8M-PLUS and DART-MX8M-PLUS and TechNexion’s EDM-G-IMX8M-PLUS and AXON-E-IMX8M-PLUS. Seco announced its SM-218 earlier this month and Adlink’s unannounced LEC-IMX8MP is on the provisional list.

As can be seen from the list of common specifications in the introduction above, the Seco and Adlink i.MX8M Plus modules have many features in common, including support for Linux and Android, short 82 x 50 mm SMARC 2.1 and support for 0-60°C or -40-85°C models. Differences include solder memory and WiFi/Bluetooth option on the SM-218 Seco and a second PCIe Gen3 interface, TSN support and shock and vibration resistance on the LEC-IMX8MP Adlink.
The NXP i.MX8M Plus is similar to the faster version of the i.MX8M Nano, but with an extra NPU of 2.3 TOPs and more coprocessors. The 14nm SoC offers up to 4 A53 cores at 1.8 GHz and Live GC7000UL 3D and GC520L 2D GPUs with 1920 x 1080 encoding and decoding at 60 frames per second. There is also a Cortex-M7 microcontroller at 800 MHz, a HiFi4 DSP at 800 MHz and up to 2 suppliers for stereo playback or a 12 megapixel camera.
SM-218
The Seco SM-218 runs Linux and Android on i.MX8M Plus Dual, Quad and Quadlite Lite, which is similar to the Quad-Core Quad, but without the VPU or NPU. The module offers weldable LPDDR4-4000 with capacities up to 8 GB and eMMC 5.1 with capacities up to 64 GB. There are two GbE controllers and the WiFi/Bluetooth LE module is optional.

The SM-218 supports two or three independent displays (optional). In addition to the HDMI 2.0a interface, there are various mixed forms of single- and/or two-channel LVDS and eDP. Other media features include 4 and 2 band MIPI-CSI and up to 2 I2S audio interfaces.
The SM-218 supports PCIe x1 Gen3, 2x USB 3.0 and up to 3x USB 2.0, including the OTG port. Additional I/O options are 2x CAN, 2x 4-wire UART, up to 2x 2-wire UART, 2x PWM and up to 14x GPIO. You also benefit from I2C, SPI, quadSPI and SMBus.
The 5V module offers watchdog, load selection and energy management functions. There is an optional SMARC Developer Kit with a 345 x 170 mm CSM-B79 support plate, which we have described in our report on the SMARC SM-C12 Seco i.MX8M based SMARC module.
LEC-IMX8MP
– CLAIM –
Adlink LEC-IMX8MP will be available with Quad or No-NPU Quad Lite i.MX8M Plus models and Yocto Linux BSP, Android support and advanced VxWorks BSP support. The module offers up to 8GB LPDDR4L-4266 and up to 64GB eMMC 5.1 with the ability to build for 128GB eMMC. Dual GbE controllers include a controller that supports TSN, but not WiFi/BT.
The LEC-IMX8MP provides HDMI 2.0a, MIPI DSI and LVDS interfaces depending on the product page, while the HDMI 2.0a specification and two separate references to 4-band DSI in two different sections. Other media features include 4- and 2-channel MIPI-CSI and 2x I2S with support for I2S audio codecs on media.
As already mentioned, the module adds a second PCIe x1 Gen3 connection. Other interfaces are 2x USB 3.0, 4x USB 2.0 including OTG, 2x CAN, 3x UART and a debug header. You also get 2x SPI, 4x I2C, SDIO and up to 14x GPIO.
Module 5B provides the SEMA board controller with a monitoring timer, load control and other functions. The resistance characteristics include 5-90% non-condensing relative humidity and shock and vibration resistance according to IEC 60068-2-64, IEC-60068-2-27 and MIL-STD-202 F standards.
