Technical Information C43-SATA • SATA/USB Mezzanine Module
J-USB3 - J-USB4
As a custom specific option, the C43-SATA can be provided with up to two horizontal mount USB
receptacles. Due to the USB connector dimensions, the total stack height of the CPU carrier board
and the C43-SATA mezzanine module assembly will exceed the 4HP envelope about ~1.3mm. This
may be tolerable in some situations, but should be nevertheless considered. USB cable assemblies
with slim and short plugs are required - not any USB harness matches with the C43-SATA due to
space restrictions. The same issue must be strictly observed if direct attachment of an USB stick
(e.g. Flash Drive) is intended - only very short, low profile sticks (with an overall length of less than
~50mm) would be suitable.
The J-USB3 receptacle cannot be populated together with the P-SATA4 connector (USB cable
assembly in conflict with SATA receptacle). For similar reasons, the J-USB4 jack cannot be stuffed
together with P-UFD1 (USB SSD memory module). Be sure to discuss your needs with [email protected]
before ordering.
The C43-SATA USB ports are derived from the ICH/PCH southbridge on the CPU carrier board. A
dual electronic switch is provided on the C43-SATA for short-circuit and overcurrent control
regarding the J-USBx receptacles (0.5A).
