Description
The Arduino UNO R4 Minima features a 32-bit RA4M1 microcontroller with a 48 MHz Arm Cortex-M4 processor, offering expanded memory (256 kB Flash, 32 kB SRAM). Compatible with existing UNO accessories, it supports 6-24 V input and has enhanced features like capacitive touch sensing, 14 digital I/O pins, and advanced ADC/DAC capabilities. Perfect for innovative projects and seamless upgrades.
Features:
- 32-bit development board, previously based on 8-bit AVR
- Standard 14 digital I/O ports, 6 analog channels, and dedicated pins for I²C, SPI, and UART connections
- Larger memory: 8 times more flash memory (256 kB) and 16 times more SRAM (32 kB)
- Easy power management: Barrel jack connector supports input voltages from 6-24 V, eliminating the need for additional circuitry
- Cross-compatibility: UNO form factor makes it compatible with existing third-party shields and accessories
Package Includes:
- 1 x Arduino UNO R4 Minima
