We’ve already seen a few DIY Raspberry Pi-based handheld computers in the past with the likes of Zero Terminal V3 or hgTerm powered by a Raspberry Pi Zero and a stripped-down Raspberry Pi 3 board respectively.
So why not another? YARH.IO Micro 2 DIY handheld PC is based on a Raspberry Pi 3B+ SBC stripped from its Ethernet port, whose double stack USB connectors have been replaced with single stack USB connectors. The DIY computer also adds off-the-shelf parts with a 4″ touch screen display and a Bluetooth keyboard without touchpad, and gets its power from a 3,500 mAh battery.
