Connection
The module has 16 pins, pitch of 2 mm.
| Pin | Description |
|---|---|
| TxD | The transmitter of the serial interface UART. |
| RxD | The receiver of the serial interface UART. |
| GPIO x | GPIO pin (digital output/ input) with a serial number. |
| GPIO 0 | GPIO with special function: To update, you need to indicate the low status (connect to GND). |
| GPIO 15 |
GPIO No. 15 with a special function: In normal and programming mode should indicate the low status (conect to GND). |
| ADC | Input of analog-to-digital converter. |
| REST | The system reset. |
|
EN (CH_PD) |
Power down - indication of low status causes a transition to sleep mode.
To update, you need to indicate a high status (3.3 V). |
| VCC | The power supply is 3.3 V. |
|
The product is compatible with Arduino Instruction of connecting the module with Arduino basing on the module ESP-01, you can find on the blog Majsterkowo and in guide prepared by us.
The board tolerates a voltage of 3.3 V. Therefore, you must choose Arduino operating with the voltage of 3.3 V or use a converter. |
