2.2.1.1 IoT Expansion Card
mangOH Yellow includes one IoT connector (CN601) that connects an IoT Expansion Card to the CF3 module’s
signals as detailed in
Table 2-2 .
This slot provides full support for the IoT Expansion Card specification. ( Figure 2-6 and Figure 2-6 illustrate the pin
positions and configuration.)
By default, specific signals are enabled when the mangOH Yellow boots. For additional information, including
default configuration and how to temporarily change it, see
IoT Connector Interfaces on page 34 .
For detailed specifications, see the Project mangOH IoT Expansion Card Design Specification available at
mangoh.io/iot-card-resources-documentation .
Important:
Do not use the UART connections on both an IoT card and a device via the expansion connector ( Expansion
Connector on page 28 ) to the mangOH Yellow at the same time.
