Hardware Component Connections - mangOH Yellow Hardware Architecture Manual

2.2.1 Hardware Component Connections

Key mangOH Yellow hardware components and their connections to the CF3 module and/or Wi-Fi+BT module are
listed in Table 2-1 on page
The mangOH Yellow's default configuration enables specific interfaces when the platform boots. For interface
details, see:
• MUXing on page 18
• CF3 Module Signals on page 19
• Wi-Fi+BT Module on page 32
• IoT Connector Interfaces on page 34
• Expansion Connector Interfaces on page 35
• Reset Methods on page 36
• Power Management on page 37
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.
