The Arduino UNO R4 Minima board is based on the Renesas RA4M1 microcontroller with a 48 MHz Arm Cortex-M4 processor. It retains the UNO R3’s standard form factor, pin layout, and 5 V operating voltage, making it easy to use compatible shields and existing projects. Built-in peripherals include a 12-bit DAC, CAN bus, and OP AMP.
The USB-C connection supports HID, allowing the board to emulate a mouse or keyboard when connected to a computer. It also features an SWD connector for connecting an external debugger.
