Upstream maintainers, not just users
Our work lands in the projects you depend on. We contribute drivers, subsystems, bootloader features and protocol stacks upstream to Zephyr RTOS, the Linux kernel, U-Boot, Yocto and Buildroot — so your product inherits less long-term maintenance.
Where we contribute
Explore our public footprint across the major embedded open-source projects.
Zephyr RTOS
Drivers, board ports, subsystems and protocol stacks — including the native OCPP 1.6 stack upstreamed to the project.
Linux kernel
Device drivers, Trusted Keys and subsystem improvements upstreamed to mainline.
U-Boot
Board support, drivers and bootloader features upstreamed to the U-Boot project.
Yocto & Buildroot
Recipe and layer maintenance across OpenEmbedded, Yocto and Buildroot.
