JQ8400 voice module

The JQ8400 voice module uses a SoC solution, which integrates a 16-bit MCU and an ADSP specifically for audio decoding. It uses hard decoding to further ensure the stability and sound quality of the system. The compact size better meets the needs of embedding in other products. SPI-flash replaces voice content. The biggest advantage of this chip is that it can flexibly replace the voice content in SPI-flash, eliminating the trouble of traditional voice chips that need to install a host computer to replace the voice. SPI FLASH directly simulates a U disk and copies the U disk. - Like, very convenient. Making product development and production convenient and simple. One-line serial port control mode and RX232 serial port control are optional, providing more selectivity for R&D 1.
