TTS Speech Synthesis Speaker Module with Serial Control for Microcontrollers

TTS Chinese Speech Synthesis Module for Microcontroller Projects This compact speech synthesis module brings clear Chinese voice output to your microcontroller projects with minimal setup. Designed for direct serial control, it lets you add spoken announcements, prompts or feedback to your builds without complex audio hardware or additional processing power. Simple Serial Control The module connects directly to the serial ports of both 1.5V and 3.3V microcontrollers, so whatever your serial port transmits is what the module speaks. For instance, sending printf("Hello everyone") from your code makes the onboard speaker broadcast the phrase in Chinese. It handles numbers, letters and Chinese text, making it a straightforward and economical way to add voice to your designs. Fixed Communication Settings Communication is kept simple with a fixed baud rate of 9600, 8 data bits, no parity and 1 stop bit, so there is no need to configure complex serial parameters. The module can also be connected straight to a USB-to-TTL adapter for quick bench testing before you integrate it into your final circuit. Clear Wiring Layout The connection leads follow a simple colour code: red for 5V, green for RX, yellow for TX and black for GND. This clear layout makes wiring straightforward, whether you are hooking it up to an Arduino, a development board or a custom PCB.
