2.2 mangOH Yellow Hardware Architecture

The mangOH Yellow platform provides several hardware components (as shown in
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
• CF3 Module Signals on page
• Wi-Fi+BT Module on page
• IoT Connector Interfaces on page
• Expansion Connector Interfaces on page
