HI, Exactly, the sdcard that comes with the unit is not propietary. I recommend that you buy the best quality 16 / 32 Gb micro-Sd you can. (My unit came with an 8Gb sandisk card) and then you download the sdcard image linked in this thread: Organelle OS version 4.0
Did your unit came with an Usb drive with patches at least?. It’s actually strange to sell an organelle without its Sdcard &/or Usb drive The wifi dongle it’s a more optional (and cheap) thing. check in the forum for recommended Wifi dongles. greetz.
