The $8 linux computer (part 1.)
Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
The Ox64, a $8 RISC-V computer capable of running Linux on three distinct cores, has begun shipping but arrives with significant limitations: Ethernet, Wi-Fi, and SD-card support are not yet functional, and programming requires UART rather than USB. Users must navigate at least six setup hurdles, including a Dev Cube flashing tool that crashes under Ubuntu on Wayland, CH340G dongles that fail handshakes, and a required patch to the bflb-mcu-tool Python library to strip DTR/RTS handling. Workarounds involve repurposing an RP2040 board such as Adafruit's KB2040 as a serial bridge loaded with picoprobe firmware. The device matters because it puts a full Unix-like environment on microcontroller-class hardware at a fraction of typical single-board computer prices, broadening access to RISC-V development. Next, watch for upstream fixes enabling the missing connectivity features and smoother flashing tooling.
