Arduino® UNO Q 1 / 31Arduino® UNO QModified: 01/10/2025 User Manual SKU: ABX00162-ABX00173 Description Arduino® UNO Q (hereafter UNO Q) is a single-board computer that combines the Qualcomm® Dragonwing™ QRB2210 Microprocessor (MPU), a quad-core Arm® Cortex®-A53 running Debian Linux OS, with the STMicroelectronics STM32U585 Microcontroller (MCU), an Arm® Cortex®-M33 running Arduino Core on Zephyr OS. The Linux system and the microcontroller communicate through Bridge, Arduino’s RPC (Remote Procedure Call) library. This allows Arduino sketches on the microcontroller to access Linux services for high-level tasks, while Linux applications can interact with microcontroller peripherals to handle real-time operations within the same project. UNO Q comes with embedded eMMC storage (options 16 GB, 32 GB) and LPDDR4X SDRAM (options 2 GB, 4 GB) to run Linux and your projects smoothly. It features dual-band Wi-Fi® 5 and Bluetooth® 5.1 for wireless connectivity, a USB- C® connector with power delivery input and video output, and Arduino-compatible headers for easy expansion with shields, carriers, and accessories. UNO Q integrates seamlessly with Arduino App Lab, enabling developers to combine Arduino sketches, Linux applications, and AI models in one environment. App Lab can run directly on the board or from a connected PC, offering ready-to-use examples, and the flexibility to create custom apps tailored to your projects.

The MPU drives the MIPI-CSI-2 camera and MIPI-DSI display interfaces on JMEDIA, and the 1.8 V MPU (SoC) GPIO and audio endpoints exposed on JMISC. JMISC is a mixed-voltage header that also carries 3.3 V MCU signals and analog audio alongside the 1.8 V MPU lines.

Arduino® UNO Q 10 / 31Arduino® UNO QModified: 01/10/2025 3 Ratings 3.1 Input Power UNO Q Input Methods SourceVoltage RangeMaximum Current Connector USB-C VBUS5 Vup to 3 A USB-C connector VIN (DC IN)7-24 V- JMEDIA, JANALOG (VIN) 5 V Pin5 Vup to 3 A JANALOG UNO Q supports dual power inputs: a USB-C port and a 7-24V DC input. Over USB Power Delivery, it requests only the 5 V / 3 A contract and does not request higher-voltage PD profiles. Use a supply and cable rated for 5 V at 3 A to avoid undervoltage during short activity peaks such as wireless bursts or display initialization. A regulated external 5 V DC source can also be used to supply power to the board via the 5 V pin on the JANALOG header. USB-C VBUS and the 5 V output of the 7-24 V buck are diode-OR combined onto the system 5 V bus (5V_SYS). From 5V_SYS, the design derives the 3.8 V pre-regulator node and, subsequently, the 3.3 V. The PMIC, powered by 5V_SYS, derives the 1.8V rail. Reverse-polarity protection: Verified with -24 V applied to DC IN. The operation is specified only with the correct polarity. Do not apply reverse voltage during normal use. Schottky OR path: Forward-voltage drop from the buck output to 5V_SYS was measured as follows (JANALOG VIN injection, Rigol DP832 supply in series, Keithley DMM6500 measurement, 8542B active load). Power dissipation is calculated as P = I × Vf.

Typical is the nominal design point. Maximum must not be exceeded. For DC_IN (7-24 V), select a supply that comfortably covers the 5 V load and use short cables to reduce voltage drop. The PWR_3P3V range reflects regulator tolerance and load. The temperature range refers to ambient air near the board, and operating near the limits can reduce available output current. 3.3 On-Board Voltage Rails Voltage RailOrigin / Regulator 5.0 V5V_SYSDiode OR of USB-C VBUS and 7-24 V buck output (both via Schottky rectifiers) 3.8 VPWR_3P8VStep-down (buck) from 5V_SYS 3.3 VPWR_3P3VStep-down (buck) from PWR_3P8V 1.8 VVREG_L15A_1P8VPM4125 LDO L15A from 5V_SYS Arduino® UNO Q 12 / 31Arduino® UNO QModified: 01/10/2025 4 Functional Overview 4.1 Pinout Arduino® UNO Q 13 / 31Arduino® UNO QModified: 01/10/2025 4.2 Power Supply UNO Q supports dual power inputs: a USB-C port and a 7-24V DC input. USB-C VBUS and the 5 V output of the 7-24 V buck are diode-OR combined onto the system 5 V bus (5V_SYS). 5V_SYS supplies the PM4125 PMIC (PMIC1) at USB_IN. The PMIC's L15A LDO provides the 1.8 V rail (VREG_L15A_1P8V) and powers the SoC I/O banks, ANX7625 DVDD18, Wi-Fi® digital logic, and the on-board level shifters. The 1.8 V rail is also available on JMISC. From 5V_SYS, a buck generates the PWR_3P8V (3.8 V) reserved for system design and future features. A second buck generates PWR_3P3V for the STM32U585, the ANX7625 (3.3 V rails), the Wi-Fi® 3.3 V domain, and the 3.3 V header pins. A protected P-channel MOSFET (Q2801) can source USB VBUS from 5V_SYS when the board operates as a USB host/OTG. The VCOIN powers only the real-time clock and does not power the Linux or MCU domains.

RGB LED 1 (D27301): channels: red:user → GPIO_41, green:user → GPIO_42, blue:user → GPIO_60. RGB LED 2 (D27302): channels: red:panic → GPIO_39, green:wlan → GPIO_40, blue:bt → GPIO_47. PWM refresh is approximately 2 kHz to support smooth color transitions. RGB LEDs (MCU-controlled): Two tri-color LEDs are driven by the STM32U585. RGB LED 3 (D27401): LED3_R → PH10, LED3_G → PH11, LED3_B → PH12. RGB LED 4 (D27402): LED4_R → PH13, LED4_G → PH14, LED4_B → PH15. LED matrix (D27001..D27104): 8 × 13 monochrome blue LED matrix (104 pixels) driven by the STM32U585. It displays the boot logo for approximately 20–30 seconds during Linux startup. Accessing the matrix before startup completes may interfere with MCU operation. Power LED (D27201): Green indicator tied to the 3.3 V rail and illuminated whenever the board is powered. Arduino® UNO Q 15 / 31Arduino® UNO QModified: 01/10/2025 6 MPU & MCU An MPU (Microprocessor unit) is a high-performance application processor designed to run a full operating system and complex software. An MCU (Microcontroller unit) is a small, power-efficient controller focused on fast, precise timing for I/O and control. UNO Q combines both to pair OS-level compute with responsive, time-critical control on a single board board and communicate through Bridge, an RPC layer implemented on both sides. 6.1 Application Processor (MPU) Qualcomm® Dragonwing™ QRB2210 is a quad-core Arm® Cortex®-A53 running Debian Linux OS.

Arduino® UNO Q 27 / 31Arduino® UNO QModified: 01/10/2025 10.4 How to Check the App Is Running Open the Console in App Lab. There are three tabs: Start-up: logs from the launch sequence, including MCU compilation and Linux deployment Main (Python®): output from the Python® application (print()) Sketch (Microcontroller): serial output from the Arduino sketch (Serial.println()) An App can launch successfully yet still have runtime issues. Check the Python® log for errors. If a sketch compilation error occurs, launch is aborted. 10.5 User Button UNO Q includes a user button (JBTN1) you can use for basic device control or custom actions from your App. UNO Q User Button Short press: reserved for user-defined actions (e.g., toggling an App feature). Support for custom short-press handling is under development. Long press (≥ 5 s): reboots the Linux system (MPU). This does not cut power to the board. Note: A long-press reboot restarts the Linux environment and may interrupt running Apps. Save work and ensure safe shutdown of external processes where applicable. The MCU continues running unless your firmware explicitly resets it.
