1. Preambles ESP-07S WiFi module is developed by Wireless-tagCo.,Ltd, core processor ESP8266 in smaller sizes of the module encapsulates Tensilica L106 integrates industry-leading ultra low power 32-bit MCU micro, with the 16-bit short mode, clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi-Fi MAC/BB/RF/PA/LNA, on-board antennas. The module supports standard IEEE802.11 b/g/n agreement, complete TCP/IP protocol stack.
ESP8266EX also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor, with on-chip SRAM, besides the Wi-Fi functionalities. ESP8266EX is often integrated with external sensors and other application specific devices through its GPIOs; codes for such applications are provided in examples in the SDK. 1.1. Features • 802.
• +20dBm output power in 802.11b mode • Operating temperature range -40C ~ 85C • Comply with FCC rules part 15 subpart C requirements 1.2. Parameters Table 1 below describes the major parameters.

ESP8266EX integrates a 10-bit analog ADC. It can be used to test the power supply voltage of VDD3P3 (Pin3 and Pin4) and the input ADC TOUT power voltage of TOUT (Pin 6). However, these two functions cannot be used simultaneously. This interface is typically used in sensor products. I2C IO14(SCL), I2C interface can be used to connect external sensor products and IO2(SDA) display screens, etc. Devices with UART interfaces can be connected with the module.

Notes: 1. Not all AT Command has four commands. 2. [] = default value, not required or may not appear 3. String values require double quotation marks, for example: AT+CWSAP="ESP756290","21030826",1,4 4. Baudrate = 115200 5. AT Commands has to be capitalized, and end with "/r/n" 4.3.2.Basic AT Command Set The ESP8266 wireless WiFi modules can be driven via the serial interface using the standard AT commands. Here is a list of some basic AT commands that can be used.
AT – Test AT startup The type of this command is "executed". It's used to test the setup function of your wireless WiFi module.
The type of this command is "executed". It’s used to restart the module. AT+GMR – View version info This AT command is used to check the version of AT commands and SDK that you are using, the type of which is "executed". AT+GSLP – Enter deep-sleep mode This command is used to invoke the deep-sleep mode of the module, the type of which is "set". A minor adjustment has to be made before the module enter this deep sleep mode, i.e., connect XPD_DCDC with EXT_RSTB via 0R.
ATE – AT commands echo This command ATE is an AT trigger command echo. It means that entered commands can be echoed back to the sender when ATE command is used. Two parameters are possible. The command returns "OK" in normal cases and "ERROR" when a parameter other than 0 or 1 was specified. AT+RESTORE – Factory reset This command is used to reset all parameters saved in flash (according to appendix), restore the factory default settings of the module.
