Product Introduction

HLK-B35S is a low-cost embedded UART WIFI (Serial Wireless Network) module launched by Hi-link Electronics. It is a WiFi+BLE combination chipset used for low-power and high-performance application development. This product is based on an embedded module that meets network standards through a serial interface, embedded with the TCP/IP protocol stack, capable of converting between user serial port and wireless network (WIFI/BLE).

Through the HLK-B35S module, traditional serial devices can transmit their data through the Internet network without changing any configuration, providing a complete and fast solution for users' serial devices to transmit data over the network.
