The etyper is a distraction-free writing device built around an Orange Pi Zero 2W running Armbian, featuring an e-paper display in a minimalist case. It supports wired USB-C keyboards and file retrieval via Bluetooth. Unlike most similar devices that use microcontrollers like ESP32, this one runs a full Linux image with pre-configured software. A Raspberry Pi port is also mentioned. The project is an entry in the 2026 Green Powered Challenge.
