HLK RM04 Wifi Module (Exterior Antenna)

HLK-RM04 is a new low-cost embedded UART-ETH-WIFI module (serial port – Ethernet -Wireless network) developed by Shenzhen Hi-Link Electronic co., Ltd. This product is an embedded module based 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 onversions.

Through the HLK-RM04 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

The HLK-RM04 module supplies designers with a prepared made part that gives a completely built-in resolution for purposes, utilizing the IEEE802.11 normal within the 2.4-2.5GHz ISM frequency band, including802.11b/g/n and likewise supplies IEEE802.3, will be rapidly and simply included in product designs. The modules combine all the RF parts required, eradicating the necessity to carry out costly RF design and check. Merchandise will be designed by merely connecting sensors and switches to the module IO pins or uart interface.

The modules use ralink’s chip Wi-fi Microcontroller, permitting designers to utilize the serial interface to attach with their gadget Therefore, this module permits designers to deliver wi-fi purposes to market within the minimal time with considerably diminished improvement effort and value.

This product is an embedded module based mostly on the common serial interface community normal,built-in TCP / IP protocol stack, enabling the person serial port, Ethernet, wi-fi community (wifi) interface between the conversions. By means of the HLK-RM04 module, the standard serial gadgets don’t want to alter any configuration; knowledge will be transmitted via the Web community. Present a fast resolution for the person’s serial gadgets to switch knowledge by way of Ethernet Additionally the HLK-RM04 module have FCC modular approvals and is compliant with EU rules.
