An optical information acquisition device that comprises a main body and a connector assembly associated with said main body and comprising three connectors. The connector assembly can be rotated with respect to said main body between a first operating position wherein said connectors extend substantially perpendicularly to a first side of said main body and a second operating position in which said connectors extend substantially perpendicularly to a second side of said main body. The three connectors are positioned at the vertices of an acute-angled triangle, more preferably at the vertices of an equilateral triangle.
