Introduction KB3071 is Bertone Technology's new embedded UART-ETH-WIFI (Serial - Ethernet - Wireless network) modules. This product is based on the universal serial interface conforms to the network standard embedded modules, built-in TCP / IP protocol stack, enables users to serial, Ethernet, Wireless (WIFI) 3 conversion between interfaces. By KB3071 module, the traditional serial devices without the need to change any configuration of circumstances, can be transmitted over the Internet through their own data network. Serial devices provide users with a complete solution for fast transmission of data over the network. 1.1 Technical Specifications Table 2-1 Technical Specifications Network Standards Wireless Standard: IEEE 802.11n, IEEE 802.11g, IEEE 802.11b standard cable: IEEE 802.3, IEEE 802.3u wireless transmission rate 11n: Up to 150Mbps 11g: Up to 54Mbps 11b: Up to 11Mbps channels 1-14 frequency range 2.4-2.4835G transmit power 12-15DBM interface 2 Ethernet ports, two serial ports, a usb port (host / slave), GPIO Onboard Antenna Antenna Antenna Type / external antenna (check one) function parameters WIFI mode wireless LAN / wireless access point / wireless router supports WDS WDS wireless bridging feature wireless security wireless MAC address filtering wireless security function switch 64/128/152 bit WEP encryption WPA-PSK / WPA2-PSK, WPA / WPA2 security mechanism for network management Remote Web Management Configuration File Import and Export WEB software upgrade serial-to-network maximum transmission rate 230400bps TCP connections maximum number of connections> 20 UDP connections Maximum number of connections> 20 baud rate 1200 ~ 230400bps other parameters Status Indicator Status Indicator Environmental Operating temperature: -20-70 ℃ Operating Humidity: 10% -90% RH (non-condensing) Storage temperature: -40-80 ℃ Storage humidity: 5% -90% RH (non- condensation) Other properties band bandwidth optional: 20MHz, 40MHz, automatic 1.1.1 Pin Pin Interface This product shown above are defined as follows: Table 2-2 Number Function Interface Module Pin Direction Description 1 VCC Power In 5V power supply input 2 GND GND ground 3 WLAN_LED O WIFI start instructions: High: search to a WIFI signal, Low: No search to a WIFI signal 4 VDD Power Out 3.3V power supply output 5 link1 O network interface connection instructions 1 6 USB_P I / O USB (Host) signal + 7 USB_M I / O USB (Host) signal - 8 GPIO_0 O GPIO_0 9 GPIO_1 O GPIO_1 10 ES I Low: Serial configuration mode, high: serial passthrough mode 11 TXOP1 A network port 1 (WAN) TX-P 12 TXON1 A network port 1 (WAN) TX-N 13 RXIP0 A network port 0 (LAN) RX-P 14 RXIN0 A network port 0 (LAN) RX-N 15 RXIN1 A network port 1 (WAN ) RX-P 16 RXIP1 A network port 1 (WAN) RX-P 17 TXON0 A network port 0 (LAN) TX-N 18 TXOP0 A network port 0 (LAN) TX-P 19 RTS_N / GPIO_2 I / O port 0 RTS (debug serial port) 20 UART2_RX I Serial 2 RX (serial communication) 21 UART2_TX O port 2 TX (serial communication) 22 RXD / GPIO_3 I / O port 0 RX (debug serial port) 23 link0 I / O network interface connection instructions 24 CTS_N 0 / GPIO_4 O port 0 CTS (debug serial port) 25 WPS / RST I WPS button / restore factory value 26 TXD / GPIO_5 O port 0 TX (debug serial port) 27 VDD_1_8 Power Out Ethernet port 1.8V output 28 VCC Power In 5V input Note: 1.
