Official Arduino UNO Q Single-Board Computer (2GB RAM, 16GB eMMC, Wi-Fi 5, BT 5.1)

A hybrid board that pairs Linux with Arduino

The Arduino UNO Q is a single board computer that combines two very different kinds of processor in the familiar UNO footprint. A Qualcomm Dragonwing QRB2210, a quad-core Arm Cortex-A53 running at 2.0GHz with an Adreno GPU for 3D graphics acceleration, handles the kind of workload usually reserved for a Linux single board computer. Alongside it sits an STM32U585, an Arm Cortex-M33 microcontroller running up to 160MHz with 2MB of flash and 786KB of SRAM, which runs the real-time, deterministic side of a project the way a conventional Arduino board would.

That combination is aimed at projects that need both: AI, multimedia or networking on the applications processor, and precise timing or sensor polling on the microcontroller, without needing two separate boards wired together.

Memory, connectivity and display

The board carries 2GB of LPDDR4 RAM and 16GB of eMMC storage, giving it enough headroom to run a Linux-class environment. Wireless is WiFi 5 on 2.4/5GHz and Bluetooth 5.1, both with onboard antennas, so no external antenna is required out of the box. A single USB-C port supports host and device role switching, power role switching and video output, and an 8x13 blue LED matrix is built in for simple visual feedback.

Interfaces exposed include I2C/I3C, SPI, PWM, CAN, UART, PSSI, GPIO, JTAG and ADC, and the board keeps the 68.85mm x 53.34mm UNO form factor, so shields and mounts designed for that footprint should still fit. Power comes from USB-C at up to 5V and 3A.

Availability and who it suits

This board pairs two very different processors on one carrier, so it suits makers moving from simple Arduino sketches into projects that need genuine Linux-class compute for AI, multimedia or networking, while keeping the deterministic microcontroller side for real-time I/O. Check current availability before planning a build around it.
