The business arm of Raspberry Pi is preparing to make an initial public offering (IPO) in London. CEO Eben Upton tells Ars that should the IPO happen, it will let Raspberry Pi’s not-for-profit side expand by “at least a factor of 2X.” And while it’s “an understandable thing” that Raspberry Pi enthusiasts could be concerned, “while I’m involved in running the thing, I don’t expect people to see any change in how we do things.”
Pretty much all the alternative SBCs are either Rockchip or Allwinner if you want ARM. There are a few RISC-V SBCs now but software support isn’t as solid and many of these lack GPUs. There are also a few x86/64 SBCs based on either older Intel Atom or newer mobile parts too.
