Blocks + BayLibre smartwatch developer

BayLibre is collaborating with Blocks as smartwatch developer.

At BayLibre, our engineers get to work on some of the most interesting technology in world. We’re equally lucky to get to work with some of the coolest companies on the planet.

BayLibre, Blocks smartwatch developer

Earlier this month Blocks announced that they are collaborating with BayLibre to develop embedded software for their forthcoming modular smart watch. We’ve been working with Blocks for quite a while and we’re thrilled to speak more about this engagement publicly!

While BayLibre has collaborated with Blocks on various parts of the embedded software stack, the part that has been talked about the most has been the port of Zephyr to the STM32L4 family of SoCs.

Blocks has been ultra-savvy about using Open Source software where it makes sense in their product, and as a result they will get to claim the honor of being the first CE device in the world to ship with Zephyr OS on board.

Without going into too much detail, Zephyr forms a critical part of the component responsible for managing the modular parts of the watch. The brain of the system remains Android-based as outlined in a Kickstarter update by Blocks.

We’re big fans of open source software, emerging technologies and cool products here at BayLibre. We’ve managed to work on all three while supporting Blocks as they move closer and closer to their ship date. We’re looking forward to seeing this seriously stylish wrist wear out in the wild!
