From the project
M.2 NVMe SSD adapter for PC Engines APU2 boards
This repo contains the hardware design for an adapter/holder combination that allows installing a 2280 M.2 NVMe SSD into a PC Engines APU2 board.
(This picture shows an older version of the design with some bodges applied, the version released here should just work out of the box, see below)
The original apu2 board only allows SD cards/mSATA SSDs for storage. The former is not very performant/durable and the latter is getting rarer/more expensive per GB. There's also a regular SATA connector, but regular SATA SSDs don't fit well into the standard enclosure.
