- Directly connects to USB to TTL modules for easy testing, simplifying development and programming tasks. - Fixed communication baud rate of 9600 bps, ensuring reliable data transmission with 8 data bits, no parity, and 1 stop bit (8,n,1). - Supports both 1.5V and 3.3V microcontroller serial ports, allowing seamless compatibility with various projects. Whatever the serial port outputs, it will be vocally reported. For example, entering 'printf("Hello everyone");' results in the speaker broadcasting "Hello everyone," effectively handling numbers, letters, and Chinese characters. This functionality makes it a convenient and economical solution for interactive applications. - Wiring sequence is straightforward: red (5V), green (RX), yellow (TX), and black (GND), allowing for simplified connections and easy integration into your existing setups. - Ideal for use in educational settings, where students can learn programming and electronics by hearing their code executed in real-time. - Suitable for hobbyists developing communication protocols between microcontrollers and sensors, providing immediate audible feedback for debugging and testing. - Useful in accessibility applications, where vocal output can assist visually impaired users in understanding data or navigating interfaces.
