Size: 20.5mm*13.7mm

Description：
With excellent RF transmission and excellent voice processing functions, this module is suitable for high-quality Bluetooth headset, Bluetooth stereo speakers and car hands-free system, and Bluetooth network access devices. BTM4805C2X module is a multi-functional Bluetooth module, which adopts the CSR BC05MM chipset. BC5-MM is a kind of multi-functional programmable chipset solution. It can realizes highly integrated on-chip radio, base band, DSP, stereo CODEC, charger and SMPS etc.. The embedded Kalimba DSP core has open processor, and advanced audio decoding (MP3/AAC/AAC+), echo cancellation, noise reduction, etc..

BTM4805C2X module provides a high quality but low cost Bluetooth voice communication solution, and it is a best choice for the high quality single-track and stereo headphones design. The built-in DSP empowers hands-free echo elimination;the way of high integrated design reduces the number of components and BOM cost, improving the cost performance. It can also applied to car hands-free devices, VoIP handheld devices, music player devices, Bluetooth adapter, USB multimedia adapter etc..audio decoding(MP3/AAC/AAC+), echo cancellation, noise reduction, etc.

For universal high-end stereo Bluetooth headphones and Bluetooth car hands-free devices can be developed, users do not need to think about programming and consider the complex RF circuit.
