Oxygen Monitoring (W5500)
mosyrf/Oxygen-Monitoring-System
This was my second year project as an electrical engineering student, and it was quite difficult because it used an STM32 controller, which I was not familiar with.

This was my second year project as an electrical engineering student, and it was quite difficult because it used an STM32 controller, which I was not familiar with. The project was also considered a failure because it did not produce any final product, only electrical designs and simulations.
Oxygen Monitoring is an open-source printed circuit board by mosyrf, from the mosyrf/Oxygen-Monitoring-System repository on GitHub. It is a 2-layer board of 102.5 × 62 mm with 121 parts on 108 nets, routed with 1,261 tracks and 114 vias.
It is built around the MAX485ED, LM2596S-5.0 and 74HC14, with the RT9193-33GB, SRV05-4 and W5100 among its other parts. Its parts include 45 capacitors, 34 resistors, 13 diodes, 7 ICs and 5 connectors. It belongs with the STM32 boards of this library.

It is required to change settings using SCLManager.exe when required for new setup.

Building a UAV as part of my final year on high school, now my hobby project

ProbablyNotArtyom/Blitz
Blitz is a 68030 based homebrew computer I designed over the course of nearly 3 years, starting in late 2017.


Loic74650/ioBoard
A relay (and more!) board with Ethernet connectivity and MQTT support

It measures 102.5 × 62 mm and has 2 copper layers, 1.6 mm thick.
121 parts, built around the MAX485ED, LM2596S-5.0, 74HC14 and RT9193-33GB. 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.
From the mosyrf/Oxygen-Monitoring-System repository on GitHub, at the commit this page was made from: the board is PCB Design/Oxygen Monitoring (W5100)/Oxygen Monitoring.kicad_pcb and its schematic PCB Design/Oxygen Monitoring (W5100)/Oxygen Monitoring.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask mosyrf before reusing the design.
