3.7.17 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.
