+# WizPad
+
+A custom 4x3 macropad with a rotary encoder, powered by the Seeed XIAO RP2040. Designed for productivity and a splash of RGB.
+
+## Inspiration & Challenges
+The WizPad was born out of a need for a compact, versatile tool to speed up my creative workflow. The main challenge was starting from zero experience and completing the design within a tight 2-hour window. I focused on a clean 4x3 matrix layout that balances functionality with a small footprint, ensuring it stays well within the 100mm limit.
