Our customers' testimonials
Red Pitayas in the classroom will offer university students an introduction to not only a wide variety of scientific and analytical instruments, but the electronics design, DSP (digital signal processing), FPGA and basic programming logic which is at the heart of many fields today.
Research Instruments Corporation incorporates a Red Pitaya into the core of its X-ray Plasma Sources. The Red Pitaya allows us to eliminate the need for a separate control computer and monitor the X-ray output in a reliable, compact and cost effective-manner. Thanks to their size, capability and reliability, Red Pitayas are the brain behind our X-ray sources going forward.
I have had the chance to have a Red Pitaya from the initial release. The device is my “go-to” desktop testing tool. Its capabilities far exceed its size. The best part is that the community is expanding as are the hardware and software options. The Red Pitaya is truly blossoming. I look forward to its future growth.
We are currently using Red Pitaya’s STEMlab 125-14 to check if communication signals are according to the specifications. We really value the versatility and portability of the board.
