Geyuan Electronics GY9300 Music Module
The GY9300 music module is a perfectly equipped with the GY9300 series (optional chip: GY9300, GY9301, GY9302, GY9303) The voice module of the MP3 chip serial port, supports the TF card driver, supports the computer to directly update the SPI Flash content, supports FAT16, FAT32 files system. Through simple UART serial instructions or one -line serial instructions, you can complete the specified music and how to play music. There is no need for tedious underlying operations, beautiful sound quality, convenient use, stable and reliable is the biggest feature of this product. In addition, this chip is also a deep -customized product. It is specially developed for the development of the field of custom speech playback. It can choose the corresponding model according to different functions. It is a streamlined version and a very cost -effective music module.

Adkey button control
The module we use is the method of AD keys, replacing the traditional matrix keyboard connection method. The advantage of this is to make full use of the more and more powerful AD function of the MCU. The design is simple and not simple. The module is configured with 1 AD port and the resistance value of 10 keys. If you are using it in an environment with strong electromagnetic interference or strong sensitivity or large-capacity load, please explain it when contacting us.
(Note: GY9300 and GY9301 support the front line serial port and UART serial function, and do not support ADKEY functions. GY9302 and GY9303 support ADKEY function, and do not support the front line serial and UART serial ports.)

MCU front line serial control
GY930X series MP3 chips support microcontroller analog first-line serial port control. This control method is simple and convenient and suitable for any microcontroller.
The first-line serial port protocols of this model are divided into GY930X and GY930XA. A sleep command has been added to the front line of the GY930X protocol. GY930XA has the same first-line serial port protocol as the previous GY910X.
