Introduction

HLK-B35 is a low-cost embedded UART-to-Wi-Fi module launched by Hi-Link Electronics, featuring a Wi-Fi + BLE combo chipset designed for low-power and high-performance application development. The module is a serial interface-based, network-standard-compliant embedded module with a built-in TCP/IP stack, enabling conversion between the user's serial port and wireless network. With the HLK-B35 module, legacy serial devices can transmit data over the internet without any configuration changes, providing a complete and rapid solution for network data transmission on serial devices.
