MSD40NBT - Enterprise-Grade Wi-Fi® and Bluetooth® in a Pluggable Module

The SDC-MSD40NBT is a Wi-Fi® and Bluetooth® module that supports 802.11a/b/g/n via an SDIO interface and Bluetooth 2.1 via a UART interface. By supporting both Wi-Fi and Bluetooth in the same module, the SDC-MSD40NBT helps device manufacturers significantly reduce system size and cost. Because it has the same interface, form factor, board connector, and pin definitions as the SDC-MSD10G and the SDC-MSD30AG, the SDC-MSD40NBT provides a smooth upgrade path to 802.11a/b/g/n and integrated Bluetooth, reducing system cost while delivering the latest wireless capabilities.

The latest EN 300 328 standard (v.1.8.1) takes effect January 2015. Please see Laird's official statement on how to achieve compliance with this new standard.

The Bluetooth SIG has introduced new changes to the certification process. Please see our blog post on the subject for more information.
