Product information
Arduino UNO R4 Minima upgrades the classic UNO with a 32-bit Renesas RA4M1 microcontroller (Arm Cortex-M4 at 48MHz), with far more processing power and memory than the R3. It adds a USB-C connector, a 12-bit DAC, a CAN bus and an op-amp, while keeping the standard form factor and 5V operating voltage.
Existing shields and accessories still fit, so it is an easy upgrade for UNO projects that need more speed or memory.
