Orca One is the first test board for Orca servers. The main purpose of the board is to give us our own hardware to start testing ORCA OS on.
The first goal is simple: get our lightweight Linux-based ORCA OS to successfully boot on hardware we designed ourselves. This board is not meant to be a powerful Orca server yet. It is a starting point for testing the hardware and software before moving onto more complicated boards.
