Overview Linkplay Wi-Fi Audio module - A88, is our 3rd generation smart audio modules developed to be used in the connected speaker, sound bar and other connected audio devices. It integrates the low power Broadcom BCM43455 Wi-Fi/BT chip and Amlogic A111 application processor. A111 is an advanced application processor designed for connected audio applications. It integrates a powerful CPU subsystem, advanced multi-format audio processing unit, a secured running environment and all major peripherals to form the low power audio AP. The main system CPU is a quad-core ARM Cortex-A5 CPU with 32KB L1 instruction and 32KB data cache for each core and a large 512KB L2 unified cache to improve system performance. Each Cortex-A5 CPU can run up to 1.5GHz and has a wide bus connecting to the memory sub-system. The main CPU handles all operating system, networking and user-interface related tasks. The audio processing engine (APE) is based on ARM® NEONTM general-purpose SIMD architecture which works seamlessly with main CPU to accelerate the multimedia processing algorithms, enhancing the user experience. It is able to decode all major audio formats up to 192KHz high resolution including MP3, AAC, WMA, RM, FLAC, OGG, etc and with the flexibility to support future audio standards. A111 also integrates all standard audio input/output interfaces including I2S, PCM and S/PDIF audio input/output for different applications. A88 module supports IEEE 802.11 a/b/g/n/ac 2.4GHz and 5GHz. It also supports BT4.2 with EDR and BLE. A88 module also provides USB, I2S, I2C, PWM, SPI, UART etc. interfaces. The firmware is fully compatible with Apple AirPlay and digital living network alliance (DLNA) streaming standards. It supports Hi-Fi audio up to 192KHz, 24-bit with most popular audio formats. It supports multi-room and multi-channel audio streaming with perfect synchronization. With this module, you can play the music on your speaker wirelessly from iPhone, iPad , iPod touch, Android devices or PC. More important, it enables the traditional speaker system to become the Internet enabled device through the wired or wireless connection provided by the module. Thus, you could freely playback any Internet audio contents such as music, podcast, radio or either the accompany audio in the movie directly from the Internet.

IC statement This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the following two conditions: (1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired operation of the device. Cet appareil est conforme aux CNR exemptes de licence d'Industrie Canada . Son fonctionnement est soumis aux deux conditions suivantes : ( 1 ) Ce dispositif ne peut causer d'interférences ; etc ( 2 ) Ce dispositif doit accepter toute interférence , y compris les interférences qui peuvent causer un mauvais fonctionnement de l'appareil. A separation distance of at least 20 cm is maintained between the transmitter's radiating structure(s) and the body of the user or nearby persons. Une distance de séparation d'au moins 20 cm est maintenue entre l'émetteur rayonnant structure (s) et le corps de l'utilisateur ou des personnes à proximité. For a host manufacture's using a certified modular, if (1) the module's IC number is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the IC number of the module is visible; then an additional permanent label referring to the enclosed module: "Contains Transmitter Module IC: " 23153-A88 " or "Contains IC: 23153-A88" must be used. This radio transmitter [ISED: 23153-A88] has been approved by Innovation, Science and Economic Development Canada to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.Warning:
