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 aquick solution for the user's serial devices to transfer data via Ethernet.Network parameterNetwork protocolWireless standard: IEEE 802.11n,IEEE 802.11g,IEEE 802.11bWired standard: IEEE 802.3, IEEE 802.3uWireless transmission rate11n: up to 150Mbps11g: up to 54Mbps11b: up to 11MbpsChannel1~14Frequency range2412~2488MhzTransmit power12~18 dBmInterface2 ethernet ports, 2serial ports, 1USB port (host/slave), GPIOAntennaAntenna typesExternalFunction parametersWIFI operating modeSTA/AP/STA+APWireless securityWireless MAC address filteringWireless safety function switch64/128/152 bit WEP encryptionWPA-PSK/ WPA2-PSK, WPA/WPA2 Security MechanismConfiguration methodSerial AT command, WEBSerial to networkNetwork connection typeTCP Server/TCP Client/ UDP Server/ UDP ClientMax No. of connections under TCP/UDP Server>20Serial port baud rate1200~500000bpsOther parametersStatus Indicator1 status indication outputEnvironment standardWorking temperature: -20~80ºCWorking humidity: 10%~90%RH (Non-condensing)Storage temperature: -40~90ºCStorage humidity: 5%~90%RH (Non-condensing)Other performanceFrequency bandwidth: 20MHz, 40MHzNotes: (retore to factory settings) In order to ensure that all of the configuration process is correct, bring the module to restore thefactory settings first. If it is already in factory mode, you can skip this step. Power on the modulewith 5V (1000mA) electric source, wait about 30 seconds, After starting, Lower RESET(pin15)pin morethan 6s (Trst), release of ES/RST feet, the system will automatically restart. After rebooting the systemthe module is already in Factory mode.Company informationFAQ(1) What is this module's chip?The chipset is MT7628NN from Mediatek(2) What storage does this module get?The RAM is 64MB, flash is 8MB(3) What is this module's supply voltage?The supply voltage is 5V with typical current 200ma(4) How many network port does this module get?2 network ports, 1WAN 1LAN(5) How can you get the order?You can contact me on e-mail or skype, then Ican make PI for you.
