Sterling™ LWB+ Datasheet 3 MODULE VARIANTS The Sterling LWB+ Module is available in three different versions. Depending on the user’s antenna and footprint needs, there is a variant to suite most application requirements. Laird Connectivity recommends that for simplicity of both the host PCB design, as well as the manufacturing process, that either the Chip Antenna or RF Connector version of the modules be used in your design. 3.

This allows time for the CBUCK regulator to discharge.

Sterling™ LWB+ Datasheet 12 HOST INTERFACE 12.1 WLAN SDIO interface The Sterling LWB+ module WLAN section supports SDIO version 2.0. for both 1-bit (25 Mbps) and 4-bit modes (100 Mbps), as well as high speed 4-bit mode (50 MHz clocks—200 Mbps). Figure 13: Signal connections to SDIO host (SD 4-bit mode) Note: Pull-ups (10K to 100K) are required on data and CMD lines. This is required during all operating states by either external resistors or through pull-ups on the host device.
PAGE 32
Sterling™ LWB+ Datasheet 12.2 Bluetooth UART interface The Sterling LWB+ uses a single UART for Bluetooth. The UART is a standard 4-wire interface (RX, TX, RTS, and CTS) with adjustable baud rates from 9600 bps to 4.0 Mbps. The interface features an automatic baud rate detection capability that returns a baud rate selection. The baud rate may be selected through a vendor specific UART HCI command to a value other than the default rate of 115.2 kbps.
