DWMEdit

DWM is a Dave Wireless Module, more detail at the DWM page.

DescriptionEdit

The DWM interface is available on the Evaluation Kit at the connector J8.

J8 is a 30-pins 0.50mm Pitch SlimStack™ Receptacle. This connector is dedicated to the DWM (optional) add-on module.

The module is built around an LS Research TiWi-BLE Integrated Transceiver Modules for WLAN 802.11 b/g/n and Bluetooth.

The module implements the necessary PHY/MAC layers to support WLAN applications in conjunction with a host processor over a SDIO interface. The module also provides a Bluetooth platform through the HCI transport layer. Both WLAN and Bluetooth share the same antenna port.
