CY920

Table 1-4 provides the GPIO assignment on the CY920

module.

TABLE 1-4: CY920 GPIO MAPPING

1.1.2 ANTENNA CONNECTOR

In the CY920 module two external antenna sockets are

used to enable diversity operation. During the diversity

operation, the firmware selects one antenna at a time

through the on-board Tx/Rx diversity RF switch.

The surface-mounted antenna socket used in the

CY920 module is Ultra Small Surface Mount Coaxial

(U.FL) type.

Note 1: The GPIO assignments are subject to change in future revisions of this document.

Note: Do not use the CY920 module that has

two external antenna sockets with only

one external antenna connected. This will

degrade the Wi-Fi or BT performance.
