CSR8635 Bluetooth 4.0 Stereo Audio Receive Board Speaker Module

CSR8635 Bluetooth 4.0 is a module that receives stereo audio and sends it to a speaker. It is based on the CSR BC8 chip BC8635, which integrates most of the Bluetooth peripheral components and optimizes the RF and audio performance. The module provides an easy-to-use solution for designing Bluetooth products. It can be used for applications such as Bluetooth speakers, car kits, headsets, etc.

Note:

1.  Audio output module for differential output, can not be directly connected with an amplifier, the circuit needs into the nondifferential signal, of course, if amplifier support can be directly connected with an amplifier IC.
2. The module of the software has two kinds, one kind is the key to boot, suitable for battery-powered occasions; one is electrically powered, adapted to the ordinary power supply occasions to use the kind of software, please note.
3. The module requires knowledge of iron welding technology and electronic technique, if does not have this condition, is likely to be a good module to your hand will become a waste, please take caution.
4. A voltage of IO the highest resistance to 1.8V module only, more than 1.8V burning module may, please note.
5.  Bluetooth modules are very sensitive to static and electric leakage, please use the constant temperature soldering iron.

Features

1. Compliant with Bluetooth v4.0 specification
2.  Highly replaceable, fully compatible with the Bluetooth modules of our other Bluetooth chips, no need to change the design to directly replace
3.  3/5 button inputs (switching / pairing / answering / hanging, play / pause, volume +, volume -, previous, next)
4.  Built-in DSP can realize echo cancellation, environmental noise elimination, EQ adjustment sound effects, etc.
5.  Module own antenna, good RF distance, and consistency
6.  128K EEPROM
7.  USB sound card function
8.  AUX-IN input switching function
