One-Stop OEM Service Customize PCB/PCBA Speaker Circuit Board Shsnd-All-SMD

Product Description

This uniquely crafted customized product is designed to meet diverse control needs, with excellent functionality as its core. Its built-in high-performance 51 core microcontroller serves as the central brain of the system, ensuring stable and efficient operation. With 2 advanced motor drive chips, it can easily handle the unidirectional rotation of up to 8 motors, or flexibly adjust to accurately control the forward and reverse rotation of 4 motors, greatly expanding the application boundaries of its functions.
What is even more remarkable is that it can achieve precise control of two two-phase stepper motors, perfectly meeting the needs of high-precision positioning and motion control. In order to provide users with a better experience, this model is specially equipped with an advanced voice chip and a spacious 4MB storage space. This ingenious design allows users to utilize WAV format single channel sound and store up to 180 seconds of content, providing clear and intuitive voice guidance for various operations and simplifying the process.
In terms of audio output, the onboard 20W amplifier chip can easily handle 4 Euro 3W full range speakers, releasing clear and loud sound quality. Whether as an alarm prompt or for entertainment playback, it can showcase an extraordinary sound experience. In terms of safety, the power input part is carefully equipped with anti reverse circuit, which can ensure the safety of the circuit board and components even in the case of reverse power connection, and build a solid defense line for the stable operation and long-term use of the equipment.
