5pcs Air602 W600 WiFi Development Board USB Interface CH340N Module Compatible with ESP8266

Feature:Support frequency range: 2.4~2.4835GHzSupport STA/AP/AP+STA functionSupport AirKiss - key distribution networkSupport TCP, UDP, HTTP, DHCP, DNS, NTP, ICMP, etc.The serial port supports RTS/CTS, and the baud rate ranges from 1200bps to 2MbpsSupport serial port transparent transmission functionSupport WIFI remote upgrade functionAT command compatible with ESP8266 (UART1 interface)Tips:It is recommended that beginners first use the USB to TTL module test, familiar with the module AT command and logic relationship and then use the microcontroller to develop.Materials required: W1FI module, USB to TTL module, DuPont lineInstructions:1. Connect the three pins of the WIFI module (GND, TX1, RX1) to the USB to TTL module.2. Access the computer, open the serial port debugging assistant, send the AT command testProjectParameterSupport WiFi standardIEEE802.11b/g/nRF system impedance50SWR-10dBFrequency Range2.4〜2.4835 GHzReceiving sensitivity20MHz MCS7@-71dBm40MHz MCS7@-68dBm54Mbps@-73dBm11Mbps@-86dBm1Mbps@-95dBmPhysical layer data rate802.11n MCS0-7150MbpsModulationDSSS, OFDM, DBPSK, DQPSK, CCK, QAM16/64Output PowerIEEE802.11b, DSSS 1Mbps, POUT = +17dBm;IEEE802.11g, OFDM 54Mbps, POUT = +10dBm;IEEE802.11n, OFDM MCS7, POUT = +10dBm;Interface TypeUART, SPI, GPIOInterface rate2Mbps@UART (Max)50Mbps@SPI (Max)Operating Voltage3.3VWorking current110mANetwork TypeSTA/AP/AP+STAEncryptionWPA-PSK/WPA2-PSKNetwork protocolTCP/UDP/ARP/ICMP/DHCP/DNS/HTTPInterface ProtocolAT+Instruction SetPacka
