CoreR4 is a learning-focused project that explores the Arduino Uno R4 WIFI from the ground up, bypassing the Arduino framework to work directly with the Renesas RA4M1 microcontroller. The goal is to understand and control the hardware at a low level using bare-metal techniques and minimal abstractions.
