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 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 5 V, making it hardware compatible with UNO form factor accessories with the same operating voltage. The Minima also includes a removable plastic backing to help keep your board safe during prototyping.
