Arduino ABX00173 UNO Q 4GB Hybrid Board QRB2210 STM32U585 development board

SKU CH-8C55-6N40F

Hybrid IoT edge board runs Linux on a Qualcomm QRB2210 MPU alongside an STM32U585 real-time MCU with 4 GB LPDDR4 RAM and 32 GB eMMC storage

  • Dual-brain hybrid power with QRB2210 MPU and STM32U585 MCU
  • AI and Linux Debian OS with Python and Arduino Sketch support
  • 4 GB LPDDR4 RAM and 32 GB eMMC storage for complex models
  • UNO form factor with LED matrix and Qwiic connector for shields
  • USB-C power with dual-band Wi-Fi 5 and Bluetooth 5.1 connectivity

Dual-Brain Hybrid Platform

The Arduino UNO Q 4GB hybrid board merges a Qualcomm Dragonwing QRB2210 microprocessor with an STM32U585 microcontroller. It targets developers who need both Linux-level processing and real-time control in the classic UNO footprint. Projects that rely on a single architecture or lack the 4 GB LPDDR4 memory will not fit this platform.

Thermals, Noise and Power

The board draws power through its USB-C connector and runs the QRB2210 at 2.0 GHz alongside the low-power STM32U585. No active cooling is fitted, so silent operation is inherent. Builders who need sustained heavy compute without a heatsink should evaluate thermal limits before committing.

Expansion and Software Impact

An 8x13 LED matrix and a Qwiic connector provide immediate visual feedback and modular sensor expansion. The 32 GB eMMC stores Debian Linux, Python environments and Arduino Sketches together. Users without USB-C power delivery or without Modulino nodes cannot use the full connectivity set.

Questions about this item

How do I attach shields to the UNO Q 4GB hybrid board without misaligning the pins?

Align the classic UNO form-factor header rows with the shield sockets, press straight down evenly, and verify the 8x13 LED matrix sits clear of the shield surface before tightening any standoffs.

Which on-board storage will wear out first and need a backup plan?

The 32 GB eMMC is the only non-volatile storage; plan periodic backups to an external device because eMMC cells have a finite write-erase cycle count.

At what temperature does the QRB2210 throttle during long AI vision workloads?

The Qualcomm Dragonwing QRB2210 reduces clock speeds when its internal thermal sensor hits the factory trip point, so sustained 2.0 GHz AI inference requires adequate airflow or a heatsink.
