Product description: WiFi module ESP-07S ESP8266 - 9 GPIO, ADC, U.FL socket
ESP-07S module based on ESP8266 chipcommunicatesin802.11 b/g/nWi-Fi standard at 2.4 GHz. This is an improved version of theESP-07 module, compared to its predecessor, the S version increased the amount of Flash memory to 4 MB, removed thebuilt-in ceramic antenna and redesignedthe tile, which gave the module greater stability. The module is equipped with 16 outputs of which 9 are general purpose GPIO pins, 1 isADC andUART bus.

WiFi module outputs ESP-07S ESP8266 - 9 GPIO, ADC, U.FL socket
| Pin | Description |
|---|---|
| TxD | UART serial interface transmitter. |
| RxD | UART serial interface receiver. |
| GPIO x | GPIO output (digital input/output) with a consecutive number. |
| GPIO 0 | GPIO with special function: To update, enter low state (connect to GND). |
| GPIO 15 |
GPIO No. 15 with special function: In the normal and programming mode, the low state must be specified (connect to GND). |
| ADC | Analogue-to-digital converter input. |
| REST | Reset the system. |

Power down - when you enter a low state, you go into sleep mode.
To update, enter high state (3.3 V). |
| VCC | Power supply - 3.3 V. |
