README
README.mdMinion - The Swiss Army Knife of Electronics
I'm a mac user, and i love my apple wired headphones. mN phone doesn't have headphone jack and my computer doesn't have micro sd or usb a. What if i made a dongle to rule all dongles, but added a potentiometer for step tracking and display + buttons to play games? And thats how I made Minion.
Features
- USB hub with usb c input, usb a and microsd output
- TRRS jack for headphones
- Bourns Rotary Encoder
- Built-in display (SSD1351)
- Tactile buttons for user input
- Robust case design with custom rotary encoder cover and button extensions

Questions
How big is the Minion PCB?
It measures 60 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Minion use?
79 parts, built around the ESP32-S3-WROOM-1-N8, USB2641I-HZH-02, AP2112K-3.3 and ADXL343BCC. 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 Minion KiCad files?
From the vibsthebot/minion repository on GitHub, at the commit this page was made from: the board is Minion.kicad_pcb and its schematic Minion.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minion design in my own project?
Its repository states no licence, so its author keeps all rights: ask vibsthebot before reusing the design.
