You can run Klipper on any Linux SBC with a USB port, RPi works but so does an old router that supports OpenWRT, a cheap Android TV box that could be flashed to run Linux, or any of the OrangePi/Banana Pi/Alliwinner H3 boards. You don't really need hardware UART because most of the printer boards you'd be using have either native USB or USB to UART converters. For that pedal, would an old Android tablet that supports USB OTG work? Because that's got to be much cheaper, and with much better SDK.

Correct. But when I looked into it a few years back fir OrangePi it was not as easy as downloading raspbian. All the images made for the pi would not work, you had to download a kernel from another place or something like that? Sorry I don't remember the details, but it was not as easy as a pi.

How much cheaper then 50 bucks can a tablet get? With the pi I can quickly in a hacky way connect rotary encoders with female-female dupon cables, use a python GPIO library made for raspberry pi.

I can also use it for Zynthian. And if I'm done with it, I can build a new printer :P

I think the part you're missing, is how expensive the Pi is now.

Buy one with a psu, and you're 100 to 150.
