COPE
This document describes key hardware aspects of the Laird WB50NBT
wireless bridge module. This document is intended to assist device
manufacturers and related parties with the integration of this module
into their host devices. Data in this document are drawn from a number
of sources including data sheets for the Laird SSD50NBT, QUALCOMM
Atheros AR6004, CSR CSR8811, and Atmel ATSAMA5D31A.
Because the LAIRD WB50NBT is currently in development stage, this
document is preliminary and the information in this document is subject
to change. Please contact Laird to obtain the most recent version of this
