Brief Introduction

HLK-RM08K is a new low-cost embedded UART-ETH-WIFI module (serial port - Ethernet - Wireless network) developed by Shenzhen Hi-Link co., Ltd This product is an embedded module based on the universal serial interface network standard, built-in TCP / IP protocol stock, enabling the user serial port, Ethernet, wireless network (wifi) interface between the conversions. Through the HLK-RM08K module, the traditional serial devices do not need to change any configuration; data can be transmitted through the Internet network. Provide a quick solution for the user’s serial devices to transfer data via Ethernet.

Serial to Ethernet

In this mode, ETH0 enable, WIFI function close. Ethernet can be configured as dynamic IP address (DHCP), can also be configured as static IP address (STATIC).

Serial to WIFI STA

In this mode, WIFI enable, module works in the STA mode, ETH function close. WIFI STA can be configured as dynamic IP address (DHCP), can also be configured as static IP address (STATIC).

Serial to WIFI AP

In this mode, WIFI enable, module works in the AP mode, ETH function close. In this mode, WIFI device can connect with the module and become the device under WIFI LAN.

Default mode

In this mode, WIFI enable, module works in the AP mode, ETH function enable. ETH0 works as WAN, ETH1-4 works as LAN. In this mode, WIFI device can connect with the module and become the device under WIFI LAN. WAN default IP is dynamic IP address. LAN, WIFI for the same local area network, enabled by default DHCP Server .
