Arduino Uno Q 4GB Development Board (ABX00173)

Embedded developers and educators use the Arduino Uno Q 4GB to prototype connected projects with a familiar Uno layout and modern ARM Cortex-M4 performance. The board runs at 5V with a 48 MHz Renesas RA4M1 microcontroller, delivering 256 KB flash and 32 KB SRAM for reliable program execution. Its 14 digital I/O pins, 6 PWM outputs, and 6 analog inputs support sensors, actuators, and communication modules. The USB-C connector provides overcurrent-protected power and programming, while an external DC jack accepts 6-24V for standalone operation. On-board UART, I2C, SPI, and CAN interfaces enable integration with industrial and automotive systems. The SWD header allows low-level debugging for advanced firmware development.
