Product Information • SCL-RHYTHM • M.2 NVMe & Quad M12 Gigabit Ethernet

Mezzanine Connectors HSE1, HSE2

The SCL-RHYTHM is provided with two male mezzanine connectors on the bottom side of the PCB,

which mate with the female mezzanine connectors on the carrier CPU card, for a resulting board-to-

board mounting height of 18.7mm (4HP effective pitch, 8HP F/P width in total).

HSE1

HSE1 is used to pass a PCIe® x4 link from the CPU carrier card to the on-board M.2 NVMe connector,

for a suitable SSD mass storage module.

HSE2

HSE2 is provided to supply the SCL-RHYTHM side card with additional PCIe® lanes. A PCIe® x1 link is

established for each of the on-board I210-IT Gigabit Ethernet controllers. This requires the CPU carrier

card HSE2 connector configured to PCIe® 4x1 (and not PCIe® 1x4 or 2x2).
