Serial Bluetooth chip module solution GY2605-B03

Bluetooth is a technology that can achieve short-distance wireless transmission. Today, Bluetooth technology has been widely used in: car Bluetooth devices, Bluetooth eye massagers, etc. In addition to these products we often use, Bluetooth audio chip modules are also widely used in : Fitness equipment, children’s toys, consumer electronics and other fields are also gradually being widely used.

Bluetooth module solution GY2605-B03

GY2605-B03 serial port Bluetooth module is an intelligent wireless audio data transmission, recording, and MP3 audio playback product independently developed by Dongguan Gyuan Electronics. It is a low-cost and high-efficiency stereo wireless transmission solution with high integration, small size, and low power consumption. , fast transmission speed and other characteristics, you only need to add a few components around the module to achieve wireless reception of high-quality stereo audio. It adopts a driver-free method. Customers only need to connect the chip to the application product to quickly realize wireless music transmission and enjoy the fun of Bluetooth chip.
GY2605-B03 mainly has three major functional features: built-in MP3 function, dual-mode Bluetooth function, and UART serial port control. The module has built-in Flash and can be plugged into U disk and TF card.
