I am about to graduate from my college and our graduate work is to design a practical appliance, you know, smart electronics and IoT is gaining popularity in recently years. During this period, I have bought several sound modules from different brands, however, I found Waytronic voice recognition module are of the best quality and with more practial function so as to faciliate the circuit design. Thanks to the products and engineers from Waytronic, I got A+ for my graduate work.
