The 5 best Intel & AMD single board computers for makers

Best Intel AMD single board computers for makers

A few weeks ago, we wrote a list of what we consider to be the top 5 most powerful Arm SBC’s and development kits, and this time around we’ll cover x86 SBC’s powered by Intel or AMD processors. But this time around, instead of focusing on the most powerful x86 single board computers which would lead to unaffordable, industrial Xeon SBC’s, we’ll be looking into the 5 best boards designed for makers. That means affordable pricing, I/O headers, and community support. The list is in no particular order. Rock Pi X – x86 on the cheap If you ever wanted the cheapest possible x86 board, Atomic Pi SBC $35 price tag was hard to beat, but it was only cheap because it was sourced from a failed robotics project, and not very convenient to use. But now in 2021, the cheapest x86 SBC that can run Windows is clearly Rock […]

ODYSSEY-X86J4125 SBC gets a faster Celeron J4125 SoC and a price increase

ODYSSEY-X86J4215

ODYSSEY-X86J4105 is an Intel Gemini Lake SBC designed for makers with Arduino compatibility thanks to a Microchip SAMD21 microcontroller, as well as Raspberry Pi headers. We reviewed the board and enclosure last year both with Windows 10 Enterprise and Ubuntu 20.04, and we also successfully tested the Arduino and Raspberry Pi GPIO headers with the latter. But the Intel Celeron J4105 quad-core Gemini Lake processor has been scheduled for discontinuance since last year, and the last order on January 22, 2021, and the final shipment on planned for July 9, 2021. So Seeed Studio had to find a replacement, and they’ve now launched ODYSSEY-X86J4125 single board computer with the same features, but switching to a slightly faster, and still available, Intel Celeron J4125 processor. ODYSSEY-X86J4125800 SBC specifications: SoC – Intel Celeron J4125 quad-core Gemini Lake Refresh processor @ 2.0 / 2.7 GHz (Turbo) / 2.4 GHz (Turbo all cores) with […]
