⚙️ Arduino UNO Q
Hybrid RISC-V + ARM Co-Processor Architecture
The Arduino UNO Q takes everything iconic about the UNO — simplicity, accessibility, and versatility — and upgrades it with dual-core hybrid intelligence.
Under its hood, the UNO Q blends a RISC-V main processor for speed and open architecture with an ARM Cortex-M33 companion core for wireless connectivity, encryption, and real-time support.
This fusion delivers both performance and precision, making the UNO Q the most advanced board in the Arduino UNO lineup — a true leap toward next-generation embedded computing.
🧠 What Makes the UNO Q Special
The UNO Q isn’t just an incremental update — it’s a reimagining of what a compact development board can do.
By combining an open RISC-V core with a low-power ARM co-processor, Arduino gives developers access to the best of both processing worlds:
- RISC-V for flexibility, high performance, and open-source instruction sets.
- ARM Cortex-M33 for reliable peripheral management, security, and communications.
Key Features
- Main Core: RISC-V (up to 240 MHz)
- Secondary Core: ARM Cortex-M33 @ 160 MHz
- Architecture: Hybrid MCU with inter-core communication
- Connectivity: Wi-Fi 6 + Bluetooth 5.3
- Security: Hardware encryption and secure boot
- Memory: 512 KB SRAM, 4 MB Flash

The UNO Q provides advanced wireless capability and faster computing while retaining the form factor and simplicity that made the UNO legendary.
⚙️ Hybrid Architecture Overview
| Processor | Type | Speed | Primary Role |
|---|---|---|---|
| RISC-V Core | Main Processor | Up to 240 MHz | High-performance computing, control logic |
| ARM Cortex-M33 | Co-Processor | 160 MHz | Wireless management, security, I/O timing |
This hybrid pairing enables developers to run complex tasks (like machine learning or signal processing) on the RISC-V core, while the ARM core manages real-time operations and secure connectivity.
