Raspberry Pi is a popular family of inexpensive single-board computers. They are often used in electronics/computing hobbyist projects including ones whose goals somewhat align with those of permacomputing.

While the Raspberry Pi is often among the best alternatives for many purposes, a particular problem with it is that it is designed for disposability rather than longevity. The cheapness and smallness of the boards may also be deceptive and make it too appealing to purchase new ones.


Most of the models are based on Broadcom SoC chips that are insufficiently documented, even though the large and active user base somewhat compensates on the problem of closed hardware.

An exception is the Pico whose microcontroller chip (RP2040) was designed by the foundation itself and has apparently a rather complete register-level documentation. An interesting feature of RP2040 is its programmable IO (PIO) that is general-purpose rather than tied to specific protocols and interfaces, while being powerful enough to e.g. generate video signals.


There are many different single-board computers, some of which based on fully documented or even open-source hardware. See single-board computer.
