From the project
Open-source and real-time orchestrator for cyber-physical-systems, to easily design, test and deploy embedded applications and digital twins.
This folder contains hardwares librairies used by Luos to inspire you to create your own designs: - L0: The base board used by Luos for demonstrastion purpose. - l0-shields: Different shields that can be used directly on the Luos L0 board for added functionality. - STm32f0discoluosshield: a debugging shield equivalent to an L0 for STM32F072B-DISCO dev board. - Breakoutboard: a small add-on board to make any board compatible with Luos L0. - wiringandpower: a set of projects for Luos L0 compatible wires and power input boards. - 00CommonLibraries: a set of Kicad libraries commonly used.
