ZW3020:
Product Introduction
ZW3020 series modules are upgraded with three core features: Firstly, it adopts optimized image acquisition and pre-processing driver, which effectively shortens the time consuming image acquisition and pre-processing; secondly, it improves the image quality and response speed after initialization.
The first is the adoption of optimized image acquisition and pre-processing driver, which effectively shortens the time consuming image acquisition and pre-processing, and improves the image quality and response speed.
Secondly, after initialization, it automatically sends 0x55 bytes handshake logo, which accurately feedbacks the module readiness status and ensures the smooth flow of receiving commands from the host computer;
Third, the new "AutoSearch" command function allows users to complete the search operation with a single command, simplifying the interaction process and enhancing the ease of use.
This simplifies the interaction process and enhances the convenience of use.
