Project of a embedded system that synchronizes signals in a plant. There is electronic (PCB) and software design (FreeRTOS for STM32F7).
Required Embedded System - Plant:
The embedded system in the pictures is what is needed for interacting with the Plant, it must send pulses and TCP messages in a specific pattern every time there is a new object incoming the plant.
HARDWARE:
The following PCB collects all the electronics part of the dessigned Embedded system
Diagram of the electronics sections. The PCB was made based on it.

Questions
How big is the Jv thesis PCB?
It measures 157.5 × 130 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Jv thesis use?
233 parts, built around the LAN8742A-CZ, USBLC6-4SC6, HCPL2630M and LTV-847. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Jv thesis KiCad files?
From the JhonVelasquez/Embedded_system_Synchronize_Plant repository on GitHub, at the commit this page was made from: the board is KICAD_Schematich/jv_thesis/jv_thesis.kicad_pcb and its schematic KICAD_Schematich/jv_thesis/jv_thesis.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Jv thesis design in my own project?
Its repository states no licence, so its author keeps all rights: ask JhonVelasquez before reusing the design.
