  • Arduino Uno Rev4 Minima
  • Offers a 32-bit development board
  • Features the standard 14 digital I/O ports
  • Based on the 32-bit RA4M1 series microcontroller
  • Comes with 256 KB Flash and 32 KB SRAM memory
  • Easy power management
  • Operating Voltage: 5 V

The Arduino Uno Rev4 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, and dedicated pins for I2C, SPI, and UART connections. Compared to its predecessors the board has a much larger memory, 8 times more flash memory (256 kB), and 16 times more SRAM (32 kB).

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 Minima has a 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 step down the voltage.

Cross Compatibility: the UNO form factor automatically makes it compatible with hundreds of existing third-party shields and other accessories.
