1 The Board

1.1 Application Examples

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 (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 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 third-party shields
and other accessories.
