Serial Wifi Server - Hlk-wr02 is a serial wifi router developed by Shenzhen Hi-Link Electronic Co.,Ltd. This product is based on on the universal serial interface network standard, built-in TCP / IP protocol stack, enabling the user serial port, Ethernet, wireless network (wifi) interface between the conversions. Through the HLK-WR02 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.

HLK-WR02 serial server features:

1 can achieve RS232 or RS485 to WIFI, RS232 or RS485 to RJ45, RJ45 to WIFI transparent transmission of data, ensure the stability of data transmission.
2 can realize Ethernet to WIFI transparent transmission module, can realize the wireless LAN cable to wireless data transformation function.
3 support AP STA mode of operation at the same time, the module can be used as AP for wireless terminal, and at the same time as the addition of STA to the other wireless routing equipment.Factory direct sales, ensure the technical support service, can also OEM and ODM

SP-WROOM-02 is a 32-bit low power micro-controller (MCU) Wi-Fi Module that integrates TCP/IP network stacks, and includes 10-bit ADC with HSPI, SDIO, UART, PWM, I2C, and I2S interfaces. The module is highly integrated. It consumes extremely low power while providing wireless internet connection for embedded devices. It can be easily integrated into resource-limited devices due to its small form factor of only 18mm x 20mm
