Unlock Open-Source FPGA Innovation with Tang Primer 25K from Sipeed - NextPCB Accelerator #8

Posted:03:24 PM April 10, 2025 writer: Carmen Zheng

At NextPCB, we’re committed to fueling the future of hardware innovation. That's why we launched the NextPCB Accelerator—a pioneering sponsorship program designed to empower developers, makers, and engineers to turn bold ideas into reality.

Working on the success of the NextPCB Accelerator campaign for Tang Nano 20K, the Tang Primer 25K from Sipeed offers more LUTs in a smaller, modular package suitable for even more customization.

Why Tang Primer 25K from Sipeed?

The Tang Primer 25K is Sipeed’s high-performance, cost-efficient FPGA core board, built around the GOWIN GW5A-LV25MG121. The second-generation Arora V FPGA chip is ideal for compute-intensive consumer, industrial, automotive and test equipment applications, delivering power-efficient processing in a cost-effective package.

Measuring just 23 x 18 mm, the Tang Primer 25K core board is an ultra-compact module delivering exceptional flexibility for applications where minimal footprint and unconventional form factors are critical—including wearable tech, handheld devices, and portable electronics. Perfect for prototyping, embedded projects, and learning FPGA design, it packs a punch in a tiny footprint.

Now eliminate barriers to FPGA adoption with Tang Primer 25K and free prototypes from NextPCB.

What's Included in the Program?

  • Free Prototyping Support: Get 2 free PCBA units, including PCB fabrication, components, assembly, and worldwide shipping (valued up to USD $500). 
  • Comprehensive Technical Support: Get expert assistance with manufacturing engineering, design guidance, certification, and production.
  • Personalized Assistance: Receive dedicated one-on-one support throughout your manufacturing journey.

Note: The sponsorship includes only the core board (Tang Primer 25K), not the dock base board. If you need a more complete solution, consider the Tang Nano 20K.

Who Can Participate?

While we prioritize business projects, we welcome hobbyist designs that contribute to the open-source community and showcase interesting applications using Tang Primer 25K. All submissions must be original - publicly available designs are not eligible for sponsorship.

Campaign participants can only take advantage of one NextPCB Accelerator sponsorship per month.

Why NextPCB?

Manufacture your Tang Primer 25K design with NextPCB to take advantage of these benefits:

  • Professional Assembly: Our precision pick-and-place machines, advanced inspection equipment, and rigorous quality control ensure reliable, high-quality results.
  • Prototype and Scale-up Assistance: From initial prototype to volume production, we provide seamless technical support—eliminating the need to coordinate multiple suppliers.
  • Batch Programming and Testing: Access comprehensive IC programming, firmware burning, and functional testing services. NextPCB offers free functional testing for up to 10 units—perfect for this free PCBA campaign.

How to Get Started
