View Information ​

  This chip's greatest advantage is its flexibility in replacing the voice content stored in the SPI-flash. This eliminates the need for traditional voice chips, which require a host computer to change the voice. The SPI FLASH can be directly simulated as a USB drive, making it as easy as copying files to a USB drive, which is highly convenient. This simplifies product development and production. The chip offers both serial control modes: RX232 serial control, providing more options for development.

By connecting the USB data cable to the chip and plugging it into a computer, the computer will automatically recognize the device, as shown in the figure below. The chip comes preloaded with 10 voice files.

Note: The voice content should not be too long to avoid running out of memory.

The module has separate IO control, one-wire serial control, and two-wire serial control.

Separate IO Control

If you need to update the voice, simply copy the desired sound and name it according to the specified format. Name the files with 5-digit numbers, such as 00001, 00002...00007.

One-wire serial control

Two-wire serial control

The baud rate is 9600, data bits: 8, stop bits: 1, parity: None.
