Product Introduction

HLK-B300 is a low-cost embedded UART-WIFI (serial wireless network) module launched by Hailingke Electronics. It is a Wi-Fi6+BLE combination chipset used for low-power and high-performance application development.

This product is based on an embedded module that complies with network standards through a serial interface, embedded with a TCP/IP protocol stack, and capable of converting between user serial ports and wireless networks (WIFI/BLE).

Through the HLK-B300 module, traditional serial devices can transmit their data over the Internet network without changing any configuration, providing a complete and fast solution for users' serial devices to transmit data over the network.
