The https://bret.dk/every-single-board-computer-i-tested-in-2025/ reviews 15 single-board computers (SBCs) released in 2025 from eight manufacturers using processors from vendors such as Rockchip, Qualcomm, Broadcom, and others. Prices ranged from $42 to $590, highlighting the growing diversity and maturity of the SBC market. The boards span several categories, including budget hobbyist devices, mid-range development boards, and high-end systems designed for specialized workloads.

The budget category under $50 included six boards with both ARM and RISC-V architectures. The Radxa Cubie A7A stood out due to its strong performance and 6GB LPDDR5 memory for only $45, outperforming other boards in the price tier.

In the $50–$100 range, the Radxa Dragon Q6A attracted attention with a Qualcomm QCS6490 processor and performance comparable to a Raspberry Pi 5 at $70. Networking-focused boards like the Banana Pi R4 targeted router and OpenWrt applications rather than general computing.

In the high-end segment, boards using the new CIX P1 SoC—such as the Radxa Orion O6N and Orange Pi 6 Plus—achieved the highest multi-core benchmark results, while the Raspberry Pi 500+ offered a refined keyboard-integrated design with 16GB RAM and NVMe support.

Overall, 2025 demonstrated rapid diversification in the SBC ecosystem. New competitors such as Qualcomm and CIX introduced powerful hardware, while RISC-V continued progressing but remained behind ARM in performance. With expanding price ranges and specialized devices for networking and AI workloads, the SBC market is becoming broader and more competitive, suggesting continued innovation in the coming years.

The project focuses on creating a desktop machine capable of fabricating circuit boards automatically, akin to 3D printing's speed and convenience. Unlike traditional methods that involve complex chemical processes, this innovation aims to simplify and speed up the production of circuit boards in-house.

The key challenge lies in developing a viable method for creating vias (connections between board layers) without using corrosive chemicals, which is crucial for enabling rapid prototyping. By eliminating chemical baths and exploring alternative techniques like conductive ink and novel electroplating approaches, the project aims to revolutionize PCB fabrication, potentially paving the way for faster and more accessible electronics prototyping on a small scale.
