1. Overview
Linkplay Wi-Fi Audio module - A76, is our third 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
BCM43438 Wi-Fi/BT chip and Ingenic X1000E application processor. The CPU is running at 1GHz with hardware
engine dedicated for floating point processing and the SIMD instruction acceleration. It supports IEEE 802.11
b/g/n/ac 2.4GHz. It also supports BT4.0 with EDR and BLE.
A76 module also provides USB, I2S, I2C, PWM, AUX in, SD/MMC 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.
