General Platform Description

The development platform is primarily based on the AM335x EVM kit by Mistral. A COM6M extension card provided by Murata serves as a wireless connectivity add-on.

Key Properties

Platform combines a AM335x EVM and a WL1271 connectivity solution
AM335x is key catalog applications processor platforms, supported worldwide by TI Sales
Wireless Connectivity Card which incorporates an Open source mac802.11 based module
Supported Technologies: WLAN and Bluetooth support
Supported OS: Linux

General Platform Block Diagram

The WL1271 connectivity solution is available in the form of a COM6M module. This board connects to the EVM main board using COM6 connector.

Because this board draws power from the Main EVM board via two sources; 1.8V VIO supply and Vbat (battery supply), no additional power source is needed to power this board.

Connectivity Expansion Card Description & COM6M Connector Pin assignment

This daughter board contains an Murata 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.
