 The Arduino UNO R4 Minima (from here on referred to as UNO R4 Minima) is the first UNO board to feature a 32-bit microcontroller. It features a RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM#AA0), which embeds a 48 MHz Arm® Cortex®-M4 microprocessor. The UNO R4's memory is larger than its predecessors, with 256 kB flash, 32 kB SRAM and 8 kB data memory (EEPROM).
 
-The UNO R4 Minima board's operating voltage is 5V, making it hardware compatible with UNO form factor accessories with the same operating voltage. Shields designed for previous UNO revisions are therefore safe to use with this board, but is not guaranteed to be software compatible due the change of microcontroller.

 The UNO R4 Minima is the first UNO series 32-bit development board, being previously based on 8-bit AVR microcontrollers. There are thousands of guides, tutorials and books written about the UNO board, where UNO R4 Minima continues its legacy.
 
-The board features the standard 14 digital I/O ports, 6 analog channels, dedicated pins for I²C, SPI and UART connections. Compared to its predecessors the board has a much larger memory: 8 times more flash memory (256KB) and 16 times more SRAM (32KB).

 **Entry level projects:** If this is your first project within coding and electronics, the UNO R4 Minima is a good fit. It is easy to get started with and has a lot of online documentation (both official + 3rd party).
 
 **Easy power management:** the UNO R4 has barrel jack connector and supports input voltages from 6-24 V. This connector is widely popular and removes the need for additional circuitry required to stepping down the voltage.
 
-**Cross compatibility:** the UNO form factor automatically makes it compatible with hundreds of existing 3rd party shields and other accessories.

 ## Digital Analog Converter (DAC)
 
 The UNO R4 Minima has a DAC with up to 12-bit resolution attached to the A0 analog pin. A DAC is used to convert a digital signal to an analog signal.
 
 ## Power Options
 
-Power can either be supplied via the VIN pin, the barrel jack, or via USB-C® connector. If power is supplied via VIN, the ISL854102FRZ buck converter steps the voltage down to 5V.

 The VUSB, barrel jack connector and VIN pins are connected to the ISL854102FRZ buck converter, with Schottky diodes in place for reverse polarity & overvoltage protection respectively. 
 
-Power via USB supplies about ~4.7V (due to Schottky drop) to the RA4M1 microcontroller.
