The YARH.IO can be customized with add on boards and adjusting the physical modules on the handheld. Certain components can be removed, like the keyboard. Because it relies on a Raspberry Pi, it supports a variety of Linux-based operating systems.
This edition is designed for the Raspberry Pi 3B+. It features a 5" touchscreen with a resolution of 800 x 480. There is a keyboard module as well as a touchpad for cursor control. It's completely portable, using a single Fenix ARB-L21-5000 5000mAh rechargeable battery that can be easily swapped for a fully charged one. It also features a DS3231 RTC clock module.
The GPIO connectors were made accessible through the bottom of the main module. This makes it possible to include any additional add-on boards. The shell used to house the components were digitally designed and 3D-printed.
You can find a list of components needed to recreate thus project yourself on the YARH.IO website. If you want to purchase a pre-made unit, you may be able to get you hands on one of the limited number of fully functional prototypes through the official shop. These currently cost $629.
