🖱ī¸âœ¨ Another cool project completed! 🚀
This project goes beyond borders, and we're thrilled to complete this project for a foreign client. 🌐

We’ve just built a USB-Keyboard Adapter using the ATmega32u4 — because who doesn’t love a little extra convenience in life, right? 💡

This beauty was originally designed for the Psion Series 5mx keyboard đŸ–Ĩī¸, but guess what? It’s compatible with most keyboards too! đŸ’Ē

Features Include:

*ATmega32u4 MCU — The heart of our design directly soldered to the board, ensuring seamless performance!
*Layout and Schematic files provided for easy access to the design 🛠ī¸
*Pre-configured Firmware — Ready for use, no hassle.
*ScanTheMatrix Sketch — A tool to map keyboards with unknown pinouts 🔌
And you know what makes this even cooler? Customizable to your heart's desire!

Feeling inspired? We can build it for you too! 😎💚

Like, comment, share — and let’s geek out together! 🖤
