TFE4205 - Studentdefinert utviklingsprosjekt: Designe tastatur
Ever wanted to craft your own custom mechanical keyboard? Here's how I brought mine to life, step-by-step! 🛠️✨
- Microcontroller Magic 🧠: Powered by the AVR64DU32 on a Curiosity Nano (cnano), this keyboard communicates seamlessly via USB-C using the Human Interface Device (HID) class. No soldering, no hassle—just plug and play!
- Custom PCB in KiCad 💻: I designed a PCB to eliminate complex wiring, ensuring a sleek, professional layout. KiCad made it easy to customize my PCB, but managing library includes can be somewhat cumbersome.
