Method: Serial at Command Hardware Interface: Serial, USB(Host), Gpio Trademark: Hi-link Transport Package: Plugin or Patch Specification: 25*16*9mm Origin: China, Guangdong HS Code: 8517629900 Product Description Embedded uart to wifi module RDA5981 2.4G HLK-M50is acost-effective embedded serial-WiFi transparent transmission module developed and produced by Hi-link Electronics. This product is an embedded module based on auniversal serial interface and conforms to network standards. Built-in TCP/IP protocol stack, which can convert between user serial port and wireless network (WiFi) interface, enabling transparent transmission of data between serial port and network TCP/UDP connection. With the M50 module, traditional serial devices can transmit their own data over the Internet without changing any configuration. Avariety of networking methods and network connection types can be customized through simple configuration, providing acomplete and fast solution for users' serial devices to transmit data over the network.Network parameterNetwork protocolWireless standard: IEEE 802.11n, IEEE 802.11g, IEEE 802.11bWireless transmission rate11n: Up to 150Mbps11g: Up to 54Mbps11b: Up to 11MbpsChannel1~11Frequency range2.4~2.4835GTransmit power15~20 dBmInterface1 serial port, 1USB port (host), GPIOAntennaAntenna typesExternal or built-in antennaFunction parametersWiFi operating modeSTA/APWireless security64/128/152 bit WEP encryptionWEP, WPA, WPA2 (CCMP, TKIP) Security Mechanism(only WPA2-CCMP is supported in AP mode. )Configuration methodSerial AT commandSerial to networkNetwork connection typeTCP Server/TCP Client/ UDP Server/ UDP ClientMax No. Of connections under TCP Server2Serial port baud rate1200~3000000BPSOther parametersStatus Indicator1 status indication outputEnvironment standardWorking temperature: -40~80ºCWorking humidity: 10%~90%RH (Non-condensing)Storage temperature: -40~85ºCStorage humidity: 5%~90%RH (Non-condensing)Other performanceFrequency bandwidth: 20MHz, 40MHz, automaticCompany informationFAQ(1) What is this module's chip?The chipset is RDA5981 from UNISOC(2) What storage does this module get?The RAM is 448KB, flash is 1MB(3) What is this module's supply voltage?The supply voltage is 3.3V with typical current 120mA(4) What is this WiFi module's advantage?This module can replace ESP8266 with high performance and low cost(5) How can you get the order?You can contact me on e-mail or skype, then Ican make PI for you.(6) What about the delivery time and shipping methods?The delivery time is 2-3 days for stock products, shipping methods can be DHL, UPS, FedEx, TNT, EMS, ect
