How can I power on my module?

...
What will I find in my 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-developedsoftware with different defaults can be built.
Contact your reference sales for further information.

Clea OS
Starting from Linux Kernel version 5.10, the Board Support Package (BSP) for this board is fully integrated within Clea OS, the operating system for the All-In-One IIot platform CLEA developed by SECO and based on Yocto. Clea OS is intended to provide the highest standards in terms of security and stability thanks to features like OTA (Over the Air) updates, double partitions, and fallback procedures. Clea OS integrates a Device Manager to communicate with the Cloud and allows a family of products to be managed as a fleet.
