pin locations and definitions of the control panel buttons and LED indicators.
All JF1 wires have been bundled into a single cable to simplify this connection. Make sure

PCI-E M.2 Slots
This motherboard has two PCI-E M.2 slots (M.2-C1/M.2-C2). The M.2, formerly known as
"Next Generation Form Factor (NGFF)" replaces a mini PCI-E slot. M.2 allows for a variety
of card sizes and offers increased functionality and spatial efficiency. The M.2 socket on the
motherboard supports PCI-E 3.0 X4 (32 Gb/s) SSD cards in the 2260, 2280 and 22110 form
factors.
