Hornet
The Hornet was designed for mounting on a printed circuit board (PCB) via 2 mm pitch 0.51
mm square pins. When integrating the Hornet into a device, be sure to leave about 1 cm (0.4")
outward from the heatsink to enable free air convection around the drive. We recommend that
the Hornet be soldered directly to the board. Alternatively, though this is not recommended,
the Hornet can be attached to socket connectors mounted on the PCB. If the PCB is enclosed in
a metal chassis, we recommend that the Hornet be screw-mounted to it as well to help with
heat dissipation. The Hornet has screw-mount holes on each corner of the heatsink for this
purpose – see below.

When the Hornet is not connected to a metal chassis, the application’s thermal profile may
require a solution for heat dissipation due to insufficient air convection. In this case, we
recommend that you connect an external heatsink. Elmo has an external heatsink (Catalog
number: WHI-HEATSINK-2) that can be ordered for this purpose – see below.
