YiHi Chipset Technology Evolution From E-Vapor Control to Multi-Industry Intelligent Control Solutions In the world of electronic vaporization, the true foundation of user experience has never been appearance or specifications alone, but the depth of control behind the system. YiHi's chipset journey began with a simple question:how to drive vaporization safely, stably, and consistently under real-world conditions. Over more than a decade of continuous development, this focus gradually shaped a control philosophy that now extends beyond e-vapor devices into multiple intelligent control applications. 2014 | The Beginning of Vapor Control In 2014, YiHi introduced the SX300 series chipset, marking its formal entry into electronic vapor control. At this stage, the priority was not complexity, but reliable power output, safety protection logic, and stable handling of different load conditions, laying the groundwork for future high-level control systems. 2015 | High-Precision Temperature Control Enters Mass Production In 2015, YiHi launched the SX350J, SX350J-V2, and SX450J chipsets. These solutions brought high-precision temperature control into mass-production environments, transforming temperature control from a niche concept into a practical and repeatable solution for everyday devices. During this period, YiHi became one of the key global technology solution providers in the electronic vapor industry. 2016 | Wireless Connectivity and System Interaction In 2016, YiHi joined the Bluetooth SIG and introduced wireless connectivity into vapor device chipsets, releasing: SX480J-BT chipset SX485J-BT chipset SX550J-BT chipset Alongside the hardware, YiHi developed its own application, SXi-Q, enabling device status display and parameter interaction. Later, due to regulatory and platform policy changes, the application was discontinued:the iOS version was removed in 2019,…
