Any device that can run a Browser such as Chrome can use QMX which includes a very robust and feature-rich POS Module, among others such as Customer Display and Kitchen Display. If you can run a Browser on a Raspberry Pi, you can use QMX.
QMX is a cross-platform web-based mobile client containing several “modules” which interact with a main SambaPOS “server” installation installed on a Windows machine, via the GraphQL API and the SambaPOS Message Server.
