Arduino® UNO R4 Minima
Enhanced and improved, the Arduino UNO R4 Minima is armed with a powerful Renesas
RA4M1 microcontroller. Brace yourself for increased processing power, expanded memory, and
a whole new level of on-board peripherals. Compatibility with existing shields and accessories
remains intact, and there's no need to make any changes to the standard form factor or 5 V
operating voltage.
• Hardware compatibility with UNO form factor
• Expanded memory and faster clock
• Extra on-board peripherals
• Extended 24 V tolerance
• SWD connector
• HID sup
