2.4.19 UART0

When the mangOH Yellow is in HL78 mode (SW403 pin 1 HL78_MODE_ON selected), UART0 is used to connect
to the Console USB connector (CN800) as shown in

2.4.20 UART1

The mangOH Yellow supports the CF3 module's UART1 signals, which connect to the IoT Connector (CN601) and
Expansion Connector (CN805) as shown in
Important:
Do not use the UART connections on both an IoT card and a device via the expansion connector to the
mangOH Yellow at the same time.
