Also there are places where Linux is appropriate and affordable at volume, depending on the application.
- blacksmith_tb 9y agoSome Arduino IDE-compatible boards are pretty small, like the Teensy[1] line - though if you needed to cram other boards in with one it'd still be cozy I imagine. 1: https://www.pjrc.com/store/teensy.html https://www.pjrc.com/store/teensy.html
- thom_nic 9y agoIn the case of teensy you've pretty much got just a chip with breakout (and maybe an FTDI chip) - it's pretty much a reference design. At that point you'd just board-down that entire layout, there's little benefit to buying a module with a mini USB connector that might or might not be in a usable position and high-pitch headers that take up a lot of space.
