~ the eulogy ~

I build computer vision that has to run on something small enough to fly, so this is the one grave in today's batch that sits inside my actual job. Gumstix sold the ancestor of the hardware I think about. In May 2004 the company put a complete Linux machine on sale that measured 20 by 80 by 8 millimeters, running an Intel PXA255 with XScale, and called it the smallest commercially available Linux computer. Nothing contradicted them.

Gordon Kruberg founded it in 2003 in Redwood City. The product was the computer-on-module: the hard parts of a working computer, meaning the processor with its memory and boot chain, on one small board with a connector on the bottom, so the thing you actually designed was a simpler carrier board underneath carrying your own ports and sensors. Kruberg is generally credited with getting there about 18 months ahead of anyone else selling the same idea.

The line that mattered to the labs was Verdex Pro and then Overo, ARM processors on a Linux 2.6 kernel, sold alongside expansion boards and the boxed Waysmall computers for people who wanted serial ports and a case. Later came Geppetto, a browser tool where you dragged a USB port or an ethernet jack onto a board outline and it did the routing for you, then quoted you a price to manufacture it. In August 2013 they attached a crowdfunding model to that, so a design with enough interest got built.

~ the stick of gum ~

The name was the specification. A board comparable in size to a stick of gum, drawing little enough power to run off a battery you could carry, with a real operating system on it rather than a microcontroller loop. For a robotics group in 2006 that combination had almost no alternative, which is why Gumstix turned up under so many research projects of that decade.

~ the funny part ~

Gumstix invented a market and then watched the cheap seats fill up. The Raspberry Pi arrived in 2012 at $35, and within a couple of years the hobbyist who would once have saved up for a Gumstix board had a better-documented machine with an HDMI port for a quarter of the price. Gumstix stayed where its margins were, selling to OEMs and industrial customers who needed a module they could design around and buy for years.

That is a defensible business right up until the volume vendors move into it too. By the 2020s a small flying machine doing anything with a camera wanted the kind of silicon that comes with a vendor's whole inference stack attached, and a 20 by 80 millimeter ARM board with a Linux 2.6 heritage was not in that conversation. The company that had been early in 2004 was late by about one generation of hardware.

~ the last time buy ~

The ending was documented properly, which is rarer than it should be. A formal letter dated 13 May 2025 went out to customers. The Last Time Buy window on the Overo series closed on 13 August 2025, remaining deliveries were worked through to the end of the year, and operations closed permanently after 31 December 2025.

Visit gumstix.com today and it answers with a page titled "Gumstix Operations Closed", carrying that notice and a link to the letter. A hardware company that spent 22 years telling engineers exactly what was on the board stayed in character for its own obituary.
