Description
The module allows you to easily connect the soldered wi-fi ESP-WROOM-32 system to the breadboard. It has LEDs that signal transmission through the UART interface, and resistors forcing a high status on EN pin (pull-up 10k) and a low status on GPIO15 pin (using resistor pull-down 10k).
Mounted wi-fi ESP-WROOM-32 system works in wi-fi 802.11 b/g/n standard at 2.4 GHz. This version is equipped with 22 GPIO pins of the UART interface: RX and TX. It has a built-in LED and a PCB antenna. Board sizes: 78 x 53 mm.

Pins
The module has a hole adapted for soldering the goldpin connectors, 2.54 mm pitch, which are included in the set. The board is adapted to the popular connectors of the breadboards.
| Pin | Description |
|---|---|
| TxD | The transmitter of the UART serial interface. |
| RxD | The receiver of the serial UART interface. |
| IOx | 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, you should indicate the low status (connect to GND). |
| Input of the analog-to-digital converter. | |
| RTS | The system reset. |
| EN | Power down - indicating the low status causes a transition to sleep mode. |
| 3.3 V | The power supply - 3.3 V. |
| GND | The ground of the system |
| SVN | Pin of the A/D converter. |
| SVP | Pin of the A/D converter. |
| S0 | Pin of the SPI interface. |
| S1 | Pin of the SPI interface. |
| S2 | Pin of the SPI interface. |
| S3 | Pin of the SPI interface. |
| CLK | Clock pin. |
| CMD | Pin of the SPI interface. |
Detailed description of the pins is inthe technical documentation.
