1. Introduction
Libre Wireless, LS5BV-N11S is a voice enabled network media module which includes a
580 MHz MIPS24K CPU core, 64MB of DDR2 DRAM memory and 16MB of Serial Flash, an
802.11n compliant 1T1R MAC/BBP/PA/RF, single port 10/100 Ethernet MDI interface,
Voice processing DSP and a USB Host.
LS5BV-N11S provides a convenient and simple voice activated method for discovering
and controlling devices, and cloud interfaces. LS5BV-N11S contains Integrated DSP for
efficient voice trigger, speech recognition and high-speed audio processing. Provides
Non-stationary and stationary noise reduction for both transmit and receive sides, and it
supports Acoustic Echo Cancellation, Barge-in, Flexible Listening Enhancement, Voice
equalizers.
The LS5BV-N11S, has very few external components required for 2.4GHz 11n wireless
products. The LS5BV-N11S employs Libre Wireless’s 2nd generation 11n technologies for
longer range and better throughput. The embedded high performance CPU can process
advanced applications effortlessly, such as Wi-Fi data processing without overloading the
host processor. In addition, the LS5BV-N11S has rich hardware interfaces (SPI/ I2S/ I2C/
UART/ USB) to enable many possible applications.
