CSR8635 Bluetooth 4.0 Беспроводной стерео модуль CSR-BC8635 аудио Динамик наушники встроенный

Module introduction

The BC8635 / 15 chip, which is CSR-enabled, provides high quality sound quality and compatibility for the module, resulting in superior overall performance. Bluetooth module using driver-free way, customers only need to access the application module products, you can quickly achieve the wireless music transmission, enjoy the fun of wireless music. At the same time can connect two main devices Bluetooth. When the module is powered on, the last two devices paired back automatically. If 6 paired devices are on at the same time, the last 2 paired devices are automatically connected.

 Applications

The module is mainly used for short-distance music transmission, which can be conveniently connected with Bluetooth devices of digital products such as notebook computers, mobile phones and PDAs to realize the wireless transmission of music.

1) Stereo Bluetooth speaker

Precautions
1. If the module antenna next to batteries, metal objects, LCD screen, speakers, etc., from the antenna distance of at least 3cm, otherwise it is recommended to use an external antenna.
2. When the layout of the power supply line is recommended to use star-shaped alignment, and to ensure that Bluetooth module power supply line performance is better. There BT and the op amp, amplifier, MCU, etc. to separate, and BT may not have other side interference, it is recommended that the Bluetooth module on the floor at the corner.
3. It is recommended to float the module antenna outside the backplane. Do not leave the control cable, power cable, audio cable, MIC, etc. around the antenna. If the module is to be placed in the middle, it must be grooved around the antenna. Set the antenna.
4. If the module antenna near the row of seats, the metal shell has metal and other signals have an impact, it is recommended to use an external antenna to solve the problem of distance.
5. Module external amplifier, must be connected to the differential input amplifier, if you do not access the differential input amplifier, you must pick an op amp to balance the two differential levels, otherwise there will be "pops" impact sound.
