Sterling-LWB5 - Dual band 802.11ac Wi-Fi + Bluetooth v4.1 Combo Module

High performance 2.4GHz and 5GHz WLAN and Bluetooth Smart Ready combo module.

LSR's Sterling-LWB5 dual-band Wi-Fi, Bluetooth® Smart, and Bluetooth® Smart Ready module offers significant value to developers by providing an unmatched breadth of options, certifications, and antenna options, offering greater flexibility for the challenging requirements of many wireless designs. This certified module is based on the Cypress (formerly Broadcom) CYW43353 chipset to create one of the very first commercially available solutions that offers IEEE 802.11ac capabilities for ultra-high data rate 5 GHz Wi-Fi connectivity, while also featuring classic Bluetooth and BLE connectivity as well. The module comes in three configurations to best address specific applications, all of which have an industrial temperature rating (-40° to +85°C) and an industry-leading range of certifications and antenna options.

Key features:

  • Delivers IEEE 802.11 ac/a/b/g/n, BT 2.1+EDR, and BLE 4.1 wireless connectivity
  • Provides 802.11ac for high-speed data applications in the 5 GHz band
  • Based on next-generation silicon from Cypress (CYW43353)
  • Three configuration options available:
    • SiP Module (10 mm x 10 mm x 1.6 mm)
    • Module with chip antenna (21 mm x 15.5 mm x 2.3 mm)
    • Module with external U.FL antenna port (21 mm x 15.5 mm x 2.3 mm)
  • Antenna and U.FL module versions are both footprint and pin compatible with Sterling-LWB
  • Enhanced collaborative co-existence algorithms
  • Direct driver support for Linux
  • SIG certified Bluetooth driver
  • Dev Board with SD card form factor for simple connectivity with NXP i.MX 6 and other platforms
