Description
The X221D carrier board only has components on the top side mounted. So it has a flat bottom, which eases the installation. Auvidea can create custom configurations with extra features by populating the USB 2.0 hub chip and components on the bottom side (e.g. micro SD/UFS card reader and extra peripheral interfaces).
The X221D carrier board features an PCIe x4 FPC extension connector to interface to the 38507 PCIe x4 slot adapter. This allows to plug in any PCIe x1 or x4 card like single or quad GbE or 10GbE adapters.
