Hardware Design Reference¶

Chipintelli provides a variety of product solution reference design schematics, which can meet most common application scenarios. In the actual application development, the customer needs to carefully select one of the most suitable reference schematics for reference and design optimization according to the specific product functional performance requirements, system characteristics and application scenarios. As Chipintelli is unable to master all product systems and application knowledge, customers or solution partners are expected to fully test and verify product functional performance (including the matching of voice chips and modules with product systems) in combination with product systems and application scenarios before mass production. If there are unclear or uncertain problems during the design modification process, please contact Chipintelli FAE/engineer for comprehensive communication.
