3.2.9 Board Mounting Hardware
The board has been designed to allow for automated build, test and handling. The locations of the four
2.8mm mounting hole are part of the HAT specification and allow the board to be mechanically fixed
onto a Raspberry Pi or enclosure. These un-plated holes are also used as tooling holes for test and ATE
fixtures.
The fiducials are copper PCB features that allow optical alignment of the board by surface mount
production equipment such as solder paste printers and pick and place machines. They are arranged on
the board so that they have no rotational symmetry.
