General HW Description and Block Diagram
The WL1271 connectivity solution is available in the form of a daughter board.This board connects to the AM1808 board. This board will be interfaced to the EVM through the Expansion connectors J29 and J30. Generally the daughter board is plugged to the connector J29 of the AM1808 EVM and the BT signals are connected using the FRC cable. The daughter board uses 5V power available on the EVM to generate the required VBAT (3.6V) and VIO (1.8V) for the WL1271 module.

Connectivity Expansion Card Description
This daughter board contains an LSR module which is based on a WL1271 Wireless LAN and a Bluetooth combo chip.

The wireless LAN and Bluetooth share one antenna which is mounted directly on the connectivity board.
