Member Quotes

Kumar Gala, Linaro IoT and Embedded Group (LITE) Technical Lead and Zephyr Project 1.14 LTS Release Manager

``With the release of Zephyr 1.14 LTS, developers can focus on differentiation with the confidence that the software they are developing on always has the important fixes and latest security updates. Linaro is pleased to have helped drive the release which provides developers with a stable set of API for real world applications on constrained devices.``

Paal Kastnes, Technical Marketing Manager with Nordic Semiconductor

“We are very excited to see that the Zephyr Project has gotten to the major milestone this LTS release is. Having the long term support option is something which is very often requested by our customers. This is especially the case for segments where development runs over longer times or for products with long lifecycles. Having the opportunity to introduce minor patches without rebasing the entire firmware framework is a major advantage for these users.”

Maureen Helm, NXP Microcontroller Software Architect and Zephyr Technical Steering Committee member

“As a founding member of the Zephyr Project, we are excited to support this latest release that brings new feature enablement and support to our expanding portfolio of i.MX RT crossover processors. The Zephyr 1.14 LTS release provides developers a well-tested, stable foundation for immediate project start and is based on a rich, open source microcontroller ecosystem that supports exciting new applications.”

Over 200 boards supported

Zephyr supports more than 200 boards. Search our list for the hardware used in your application. This diversity of supported boards gives developers and product manufacturers multiple options to solve their embedded RTOS challenges with Zephyr. If your board is not supported out of the box, adding support for a new board is simple.
