Interfaces Note: Meteor Lake COM Express Type 6 dev kit consists of a COM Express Type 6 module powered by Intel® Core™ Ultra Processor and a COM.0 R3.1-compliant carrier board. This page aims to lay out the user’s interface of Meteor Lake COM Express Type 6 dev kit. Connector Pinouts and Signal DescriptionsPCIe Gen4 x16One x8 and one x4 and one x4 PCIe lanes offered at this x16 slot. Plug-in PCIe devices here will get one PCIe Gen4x8 support in default. A PCIe adapter card, separate the PCIe lanes into one x8, one x4, one x4, can be used for functionality test purpose. PCIe adapter card, for example, PCIEX16E-844S.
