Modular Link MX93 (SF-E39-ML)
Depending on the configuration and following revisions, the features of the board are subject to change. For detailed information on hardware specifications, please visit www.seco.com
SECO Modular Link MX93 is a DIN rail, fanless industrial gateway designed for streamlined integration through a modular, stackable architecture, using a custom connector to add Daughter systems and extend I/O and power distribution. 
It is based on the NXP i.MX93 platform (2x Arm Cortex-A55 up to 1.5GHz plus Arm Cortex-M33, with Arm Ethos U-65 microNPU), with up to 2GB LPDDR4, up to 32GB soldered eMMC, and optional MiniHDMI for up to 1080p at 60Hz. 
On connectivity, it supports up to 2x Gigabit Ethernet, dual USB 2.0 Type-A (one with OTG capability), an RJ12 software-configurable serial port (RS-232, RS-422, RS-485), plus a debug UART over USB Type-C. Wireless options include onboard Wi-Fi and Bluetooth, and a full-size miniPCIe slot for an optional LTE modem with nanoSIM and external antennas. 
For field deployment, it supports 12 to 36 VDC input, runs Clea OS (Linux Yocto), includes TPM 2.0, RTC and watchdog, and is specified for -20°C to +70°C operating temperature in a 140 x 96 x 36 mm enclosure.
For ordering purposes, Modular Link MX93 is referred to by its base code, "SF-E39-ML".

What is loaded in a standard module?
Off-the-shelf products are shipped with a standard in-house-developed software. The definition of standard, in this case, is “the environment which SECO adopts for validation”. Anyway, custom in-house-developed software with different defaults can be built. Contact your reference sales for further information.
Clea OS
All off-the-shelf products are shipped with Clea OS preinstalled as the standard software environment. Clea OS is a versatile and robust Linux Operating System framework designed specifically for industrial embedded devices. Based on the open source Yocto Project, Clea OS offers a flexible and customizable platform that can be tailored to meet the specific needs of various hardware architectures and applications.
Starting with Linux Kernel 6.6, the Board Support Package (BSP) for this board is fully integrated into Clea OS. It ensures high security and stability through features like OTA (Over-the-Air) updates, dual partitions, and fallback procedures. Additionally, Clea OS includes a complete device manager for seamless cloud communication, enabling centralized management of product fleets.
