Bluetooth Amplifier PCB Module
The Tectonic Elements TEAM-DBA3-301 is a fully integrated amplifier PCB module for high-efficiency battery-powered Bluetooth speakers. Wireless communications are performed by an integral Bluetooth sub-module with on-board antenna. The module is complete with A2DP, HFP, and AVRCP 1.4 Bluetooth profiles, and AAC and apt-X are also supported subject to licencing agreements. The TEAM-DBA3-301 module exhibits class-leading battery life, and is powered by a 3.7V lithium-ion battery (not included), which may be of multiple parallel cell construction for higher capacity. Sophisticated battery management is included for recharging the battery and simultaneously powering the system from an AC adaptor or USB port.
