Page 6: Overview
The CompuLab product line of industrial PCs is designed to support custom functionality and I/O extensions with FACE (Function And Connectivity Extension) modules. FACE modules are implemented by an internal extension board and a simple sheet-metal panel. The extension board is connected to the PC motherboard with two board-to-board connectors featuring standard PC interfaces such as PCIe, USB2, SATA, SMBus etc. -
