2.2.3.2 Add-in Card Connectors
The board has the following add-in card connectors:
• One PCI Express 1.0a x1 connector. The x1 interface supports simultaneous
transfer speeds up to 250 MB/s of peak bandwidth per lane, per direction, for up to
500 MB/s concurrent and bi-directional bandwidth.
• One PCI Express Half-Mini Card slot
• One PCI Express Full-/Half-Mini Card slot (removable stand-offs in full-length keep
out zone allows repurposing of Full-Mini Card slot into Half-Mini Card slot)
2.2.3.3 Power Supply Connectors
The board supports wide-range voltage input by either of the following power supply
types:
• External Power Supply – the board can be powered with an 8 - 19 VDC external
power supply though the DC jack on the back panel. This connector accepts dual-
barrel plugs with an inner diameter (ID) of 2.5 mm and an outer diameter (OD) of
5.5 mm, where the inner contact is +8 (±10%) through +19 (±10%) VDC and the
shell is GND. The maximum current rating for this connector is 8 A.
• Internal Power Supply – the board can alternatively be powered via the internal
1 x 2 power connector, where pin 1 is GND and pin 2 is +8 (±10%) through +19
(±10%) VDC. The maximum current rating for this connector is 10 A.
