If the user intends to use a mini-PCIe card on the dev kit that requires a USB connection, then the
Mini-PCIe USB enable DIP switch S2401 (6) must be switched to closed / ON. See Figure 6. Mini-
PCIe USB Enable DIP Switch (6). If the DIP switch is closed, the USB 3.1 Type A connector J2400
(5) is not functional.

Digital IO Expansion Header J2200 (23)
The Open-Q 845 µSOM Development Kit includes a digital IO expansion header J2200 which
provides access to a selection of µSOM GPIO signals and power rails. See item 23 in Figure 1 for
the carrier board location of this header. The pinout for this header is shown in the table below.

Sensor IO Expansion Header J2100 (21)
The Open-Q 845 µSOM Development Kit includes a sensor expansion header J2100 which provides
a connection to an optional sensor board. If sensor functionality is not required, this header may be
used for other applications. See item 21 in Figure 1 for the carrier board location of this header. The
pinout for this header is shown in the table below.
