@Salota_Atajawa and I are in preparation to roll out Kolibri to her prior teaching school in Sumba, Indonesia in November, or to her tutoring students. I’ll be heading to Indonesia in August.
The exact configuration of devices I’m still planning/ordering/finalising. I’m either going to use a server with multiple clients, or just a server that is also the client. Devices will either be Raspberry Pi 5, Raspberry Pi 4, or Raspberry Pi 400. I’m thinking endurance sd-cards are fine for server and clients, with say 64GB for clients and 256GB for the server.
I had looked into Pine64, seems promising but too risky for me at this experimental stage of the rollout.
