EB35W1M Bluetooth Stereo Audio Module
Product Description
The EB35W1M Bluetooth stereo audio module is based on CSR BC05 chip BC57E687. The
module has been integrated with most of the peripheral components and fully tuned to obtain
best RF and audio performance, thus make it a simple plug and play solution for Bluetooth
products design. This mass production proven module helps OEM customers to achieve high
yield rate and reduce the time to market.
EB35W1M is complaint with Bluetooth V2.0+EDR, and supports A2DP, AVRCP, HS, HF
profiles, it mainly targets on Bluetooth stereo applications like Bluetooth speakers, Car-kits, it
has been designed with the stereo application specified requirements in mind. The embedded
Kalimba DSP enables sound effects as echo cancelation, noise cancelation, SRS sound
functions. The module also features a UART connection to let the master MCU to have the full
access of the Bluetooth functions.
