By default, specific signals are enabled when the mangOH Yellow boots. For additional information, including
default configuration and how to temporarily change it, see
For detailed specifications, see the Project mangOH IoT Expansion Card Design Specification available at

Important:
Do not use the UART connections on both an IoT card and a device via the expansion connector
