2.2 mangOH Yellow Hardware Architecture
The mangOH Yellow platform provides several hardware components (as shown in Figure 2-2 on page 8 and
Figure 2-3 on page 9 ), including:
• CF3 module socket
• Wi-Fi+BT module (USI WM-BN-CYW-48)
• Pluggable IoT Connector (socket for IoT Expansion Card)
• Several I/O connectors (SIM, SD, Audio, USB, etc.)
• Expansion Connector
Figure 2-4 illustrates the mangOH Yellow’s default hardware architecture (connectors and signals). The following
sections describe these features in greater detail:
• Hardware Component Connections on page 11 —mangOH Yellow hardware components overview.
• CF3 Module Signals on page 19 —CF3 module connections to hardware components.
• Wi-Fi+BT Module on page 32 —Wi-Fi+BT module connections to hardware components.
• IoT Connector Interfaces on page 34 —IoT Expansion Card signal connections to the hardware components.
• Expansion Connector Interfaces on page 35 —Expansion connector signal connections to the hardware
components.
