Overview
Hermes is an open-source printed circuit board by Awesome-XV, from the Awesome-XV/Hermes repository on GitHub. It is a 2-layer board of 73.4 × 40.1 mm with 15 parts on 23 nets, routed with 127 tracks and 5 vias.
It is built around the D6R90 F2 LFS. Its parts include 5 resistors, 3 connectors, 2 capacitors, 2 ICs and 2 diodes. It belongs with the RP2040 boards of this library.
Main components

README.mdHermes
This is a project that detects motion/object presence. It uses a TOF distance sensor to detect an object moving or in general. Once the sensor detects it, it sends the signal to the LED to flash. There is also a button that allows for the ability to change units and modes. This makes it work like a motion sensor too, batteries have been included for better mobility and placement of this device.
Why
I made this project so I can do more complex things in Kicad and have a better understanding on how to use footprints and symbols. This is the first time that I had to go and find them completely on my own. I also added SMD components that will make it cooler. I also added an OLED screen that I can integrate functionality into. Overall, its just a complexity upgrade from my last project so that I can get more into hardware

Questions
How big is the Hermes PCB?
It measures 73.4 × 40.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hermes use?
15 parts, built around the D6R90 F2 LFS. 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 Hermes KiCad files?
From the Awesome-XV/Hermes repository on GitHub, at the commit this page was made from: the board is Kicad-Files/Hermes.kicad_pcb and its schematic Kicad-Files/Hermes.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hermes design in my own project?
Its repository states no licence, so its author keeps all rights: ask Awesome-XV before reusing the design.
