+3.3V supply
The PCIe interface has a dedicated 3.3V regulator. For power consumption management, this
regulator can be controlled through I/O expander PCIE_VCC_EN/IO27 signal.
The ConnectCore 6UL SBC Pro has four 2.6 mm metalized drills: two for the half-size and two for the
full-size mechanization. These drills have a 5.8 mm x 5.8 mm area without parts or routes for the
screws and nuts. To install a PCI Express mini card on the ConnectCore 6UL SBC Pro, you need two
M2.5 nuts, two M2.5 screws, two 4 mm M2.5 spacers, and two M2.5 washers.
The following table shows the pinout of the PCI Express Mini card connector:
