Qualcomm acquires Arduino, introduces Arduino UNO Q “dual-brain” SBC

Qualcomm has just signed an agreement to acquire Arduino, and the goal of the purchase is to “combine Qualcomm’s leading-edge products and technologies with Arduino’s vast ecosystem and community to empower businesses, students, entrepreneurs, tech professionals, educators, and enthusiasts to quickly and easily bring ideas to life.” They also took the opportunity to launch the Arduino UNO Q “dual-brain” SBC powered by a Qualcomm DragonWing QRB2210 SoC running Linux and an STMicro STM32U585 MCU for real-time control, as well as the Arduino App Lab integrated development environment to “unify the Arduino journey across Real‑time OS, Linux, Python, and AI flows”. Will the acquisition change anything? I suppose we’ll see more and more Arduino boards based on Qualcomm processors, but the company also promises to preserve Arduino’s open approach and community: Arduino will retain its independent brand, tools, and mission, while continuing to support a wide range of microcontrollers and microprocessors […]
