Description of Arduino Uno R4 Minima  :

The Arduino Uno R4 Minima represents an evolution of the classic Arduino Uno development board, upgrading the 8-bit AVR microcontroller to a 32-bit Arm Cortex-M4 while retaining the same form factor. This allows enhanced performance and memory in a familiar package compatible with existing Arduino shields and accessories.

At the heart of the board lies the Renesas R7FA4M1AB3CFM#AA0 microcontroller, containing a 48MHz Arm Cortex-M4 processor with floating point unit and 256KB of flash memory. This provides approximately 8 times more flash and 16 times more SRAM compared to the Atmega328P found on the Uno R3.

The R7FA4M1AB3CFM#AA0 microcontroller features a 12-bit ADC, on-chip touch sensing, multiple serial interfaces, DMA controllers, and more capabilities. The Uno R4 Minima runs at 5V, ensuring compatibility with shields assuming a 5V logic level. Power can come via the USB-C port, barrel jack or VIN pin, with an on-board buck converter stepping higher voltages down to 5V.
