Product Introduction
HLK-B35S
The core competitiveness of HLK-B35S lies in its dual-mode wireless communication capability and extreme power control.
In traditional IoT applications, devices often need to support both Bluetooth and Wi-Fi simultaneously, for example, a smart lock requires Bluetooth for close-range control and Wi-Fi for remote management.
Previously, such requirements often necessitated two separate communication chips, which not only increased hardware costs but also led to higher power consumption and larger PCB footprint. The HLK-B35S effectively solves this problem by integrating two communication protocols into a single chip, enabling device manufacturers to achieve more flexible network connection solutions at a lower cost.
