 # Description 
 
-The Arduino® 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 much 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 Arduino UNO has long been the best board to get started with electronics and coding. And the UNO R4 Minima brings with it, apart from the upgrades to clock speed, a 12bit DAC, a 32bit microcontroller, and low level debugging.
+The Arduino UNO R4 Minima is the first UNO board featuring a 32-bit microcontroller. With a new architecture based on the RA4M1 MCU from [Renesas](https://www.renesas.com/us/en), it is faster with its 48 MHz clock, has a lot more memory and brings new features such as a built-in RTC, DAC, HID support, CAN bus, JTAG connector and more.
 
-The UNO is the most used and documented board of the whole Arduino family, and in this flavour the UNO can do more than ever. 
+The board still features the classic barrel jack plug, with an improved voltage input range (6-24V), but replaces the old USB connector with a USB-C type connector. The UNO R4 Minima remains on a 5V operating voltage, making it hardware compatible with shields, accessories or circuits designed for older UNO revisions.
