Module Development Guidelines

Module functionality is only limited to one's imagination subject to available AP power. Applications can include, but are not limited to, RF non-WiFi technologies, environmental monitoring/control, Fog, or compute/cache engines.

Below summarizes key high level module connectivity considerations.

Golden Finger Pin Assignments

The module must implement edge connector fingers (or Golden Fingers Connector) that must mate with a standard right-angle PCIe x4 card edge connector located on the AP3802. The pin assignments for the port are listed here.

Minimum Module Connectivity

The minimum connection requirements for a module functionality are:

• SGMII host ethernet connectivity
• 12VDC host power
• Host driven reset line
• I2C Serial IDPROM for module identification
• Module presence detection
• Coexistence signaling for 2.4/5GHz radios if relevant
• UART to help diagnose issues with modules. Cisco recommends that third party developed modules have a UART interface for troubleshooting purposes.
