The Red Pitaya community has grown to over 150,000 engineers, students, and researchers worldwide, encompassing 5,000 industrial customers, more than 1,500 universities, and nearly 700 research institutes. Its platforms are trusted by some of the world's most advanced innovation hubs, from quantum labs and aerospace R&D centers to top-tier engineering schools and emerging technology companies.
The STEMlab Gen 2 architecture is built on a decade of field experience. It offers improved RF input performance, reduced noise and distortion, and a modernized hardware stack that ensures reliable operation in both laboratory and harsh industrial environments. The new system operating system and power management module, which includes eMMC storage and monitoring capabilities, enables faster boot times, remote updates, and increased resilience.
Red Pitaya boards, which have already proven their effectiveness in real-world implementations, are used in a wide range of industrial and scientific applications, from aerospace testing to renewable energy systems and quantum measurement laboratories. Colorado-based LongPath Technologies has integrated Red Pitaya STEMlab PRO Gen 2 into its laser-based methane detection network, which monitors greenhouse gas emissions across hundreds of square kilometers.
“With Gen 2, we’ve seen improved frequency stability compared to the original boards, along with reduced harmonic noise in both the ADCs and DACs,” says Colin Wargo, senior electrical engineer at LongPath Technologies. “These improvements translate directly into cleaner signals, better detection of weak signals, and greater stability.”.
LongPath's system, based on Nobel Prize-winning dual-frequency comb spectroscopy, demonstrates how compact, FPGA-enabled data acquisition hardware can bring precision laser physics from the lab to large-scale industrial implementation.
The STEMlab 125-14 Gen 2 series, comprising the STEMlab PRO Gen 2 and the PRO Z7020 Gen 2, is now available in all configurations for immediate order through the Red Pitaya online store and distributors such as DigiKey, Mouser, and Farnell. Each model maintains full backward compatibility while offering measurable improvements in analog isolation, synchronization, and signal quality.
Red Pitaya will be showcasing the Gen 2 family at Embedded World North America 2025 (booth #9042, Anaheim Convention Center), where visitors can see live demonstrations of FPGA-based signal acquisition and control.
“Gen 2 transforms Red Pitaya from an R&D platform into a proven industrial instrument,” said Mateja Lampe Rupnik, CEO of Red Pitaya. “The growth of our community, from a few hundred pioneering users to tens of thousands of engineers and researchers, demonstrates that user-friendly hardware for developers can deliver truly industrial results. We are seeing our users deploy it in environments that demand precision, reliability, and long-term operation—from quantum labs to methane monitoring networks.”.
“The response from early partners like LongPath Technologies confirms the value of combining open-source software with high-performance, deterministic hardware,” added Črt Valentinčič, CTO of Red Pitaya. “As Gen 2 is rolled out globally, it enables engineers to move from prototypes to production faster than ever before.”.
