OPEN-SMART USB to ESP8266 ESP-12 Wi-Fi Module w/ Built-in PCB Antenna
USB to ESP-12 adapter module has CH340G USB to TTL driver IC onboard£¬ so you can easily use your computer to do ESP-12 functional debugging. ESP-12 is WiFi serial transceiver module£¬ based on ESP8266 SoC.The SOC has Integrated TCP/IP protocol stack.It is TTL serial communication interface and its parameters can be set by AT command. It is widely used in networking£¬ smart home project when it is connected to the wifi router. It can be used for remote monitoring of home appliances£¬ bedroom temperature and humidity£¬ controlling home appliances and smart car by the mobile phone. Features: - Working voltage: 4.5V~5.5V (On-board 3.3v LDO Regulator) - Working current: 300mA(LDO regulator can supply) - Selectable working mode: On-board toggle switch. UART side for serial TTL debugging by AT commands£¬ PROG for firmware programming - USB to serial TTL chip: CH340G - Logic level: 3.3V - Serial port baud rate: 115200 (default)£¬ can be modified to other values ?by AT command - Serial communication format: 8N1 - On-board reset button - On-board switch to select UART mode or firmware update mode - Antenna Type: Built-in PCB antenna is available. - Wireless Network Mode: station / softAP / SoftAP + station - Wireless criteria: 802.11 b / g / n - WIFI @ 2.4 GHz£¬ support for WPA / WPA2 security mode - It is very easy to design projects by AT command
