The $8 Linux Computer (2022)

The Ox64 is an $8 RISC-V computer capable of running Linux, featuring three processor cores and behaving like a UNIX machine despite its microcontroller appearance. However, setting it up is extremely challenging, requiring workarounds such as using an RP2040 as a serial bridge, modifying flashing tools, and programming via UART pins instead of standard USB connections. Currently, key features like ethernet, WiFi, and SD-card functionality are non-operational.
