The New Red Pitaya Upgraded for Industrial DAQ Applications

Red Pitaya started with its simple development boards that have served more than 30,000 enthusiasts, universities, and companies around the world with their engineering projects. In the last years, they felt an increased need for a more sophisticated, high-end platform. To provide an enhanced product, Red Pitaya teamed up with engineers from Instrumentation Technologies and designed a product made to meet the needs of more demanding users for industrial, research, test and measurement, and data acquisition applications. STEMlab 250-12™ offers enhanced hardware performance, complete software control, and additional hardware features over Red Pitaya's previous products. Its larger FPGA enables greater real-time processing capabilities plus faster analog front and back-end performance. Small and portable, it also offers the benefits of remote access with a web app user interface accessible through Ethernet or Wi-Fi.

Many companies across different industry segments used Red Pitaya for concept prototyping and while they were satisfied with its performance as a general-purpose device, they were looking for something more robust and capable of more detailed measurements. These companies are looking for a device that could be customized and successfully upgraded and integrated into their solution or existing products, thus cost optimizing their solution.

We are happy to say that our group of engineers at Instrumentation Technologies were able to provide such results for many companies based on our three-step solution. Here's how we do it:

STEP 1: In the first step, we evaluate your specific situation and provide a Red Pitaya to test in your environment. During the testing period, we can assess whether Red Pitaya is a good base device for data acquisition measurements. Since Red Pitaya is quite powerful, there is a possibility of oversampling. This step aims to get a complete understanding of your problem and provide hands-on feedback and a potential solution.

STEP 2: In the second step, we define your requirements based on initial testing in step 1. Our team of engineers will define the scope of your needs and prepare a tailor-made solution both on the hardware and software side. This step aims to upgrade the Red Pitaya features and capabilities to provide better results from the prototype solution. Our objective is to enhance Red Pitaya's performance to target the exact problem you are facing.

STEP 3: If we come to a satisfying agreement in step 2, then we proceed with the development of a customized data acquisition device for your company. The device is 100% tailor-made based on your requirements – higher or lower sampling rates, different form factors, ruggedized design with industrial or automotive grade components, etc. The decision is truly up to you.

Our objective is to transit from general-purpose devices like Red Pitaya's STEMlab to sophisticated industrial solutions tailored to your needs, based on our DAQ building blocks.

Using our expertise and existing edge devices and following the three steps, we come to the development of a specific DAQ device. As an example, one of our customers has used a set of Red Pitaya's STEMlab boards and learned that their needs are limited using a general-purpose device. As a result, we've teamed up and we developed a tailored solution – a heavily ruggedized device with dynamic sampling rates, ranging from 100 MS/s up to 1 GS/s and wireless communication.
