Specifications:

The Arduino Uno R4 Minima (ABX00080) is a significant update to the Uno series, featuring a 32-bit ARM microcontroller, the Renesas RA4M1, which marks a departure from the 8-bit microcontrollers used in previous versions. This board operates at 5V and is designed to offer a blend of increased processing power, memory, and enhanced features while maintaining compatibility with existing Uno R3 shields and accessories.

Key technical specifications include:

• Microcontroller: Renesas RA4M1 (Arm Cortex-M4 with Floating Point Unit)
• Operating Voltage: 5V
• Clock Speed: 48 MHz
• Memory: 256 KB Flash, 32 KB SRAM, and 8 KB EEPROM
• Digital I/O Pins: 14, with 6 providing PWM output
• Analog Input Pins: 6, supporting up to 14-bit resolution
• DAC (Digital-to-Analog Converter): 1, for advanced audio projects
• Communication Interfaces: UART, I2C, SPI, and CAN (requires an external transceiver)
• USB: USB-C for programming and HID (Human Interface Device) support, allowing it to emulate a keyboard or mouse
• Input Voltage (VIN): 6-24V, accommodating a broader range of power supplies
• The Uno R4 Minima also introduces a built-in Real-Time Clock (RTC) for accurate timekeeping and alarm functions, and a DAC for sophisticated audio projects. It’s the first in the Uno series to feature a USB-C® connector, enhancing its connectivity options.
