The Arduino Uno R4 WiFi: What were they hiding?

The UNO R4 was created with maximum compatibility in mind and keeps the same physical factor, compatibility with shields, and 5V operating voltage as its predecessor. The Renesas RA4M1 32-bit Cortex-M4 CPU, which powers the UNO R4, significantly increases processing speed, memory capacity, and functionality.
