**X-NODE MCU WIFI BLE (ESP32-S3)** based around the wireless connectivity module [ESP32-S3-WROOM-1](https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-1_wroom-1u_datasheet_en.pdf) from [Espressif Systems®](https://www.espressif.com/en), featuring Bluetooth/BLE and 2.4 GHz Wi-Fi, with two operating modes to use it as an X-NODE (Peripheral) or as an X-BOARD (Controller). It is compatible with USB 2.0 OTG, I2C, UART, and SPI protocols. It includes multiple power modes and dynamic power scaling, contributing to an optimal balance between communication range, data rate, and energy consumption. It is ideal for low-power applications, mobile applications, wearables, and the Internet of Things (IoT), such as interacting with a sensor, actuator, or even a home automation system, with monitoring and control from a computer or cloud service.

{% hint style="info" %}
The BOOT push-button is connected to GPIO0 with a pull-up configuration.

#### Auxiliary Programming Port

The **X-NODE MCU WIFI BLE (ESP32-S3)** can be programmed and debugged through the USB Type-C interface. However, in applications where the USB protocol of the microcontroller is used, the auxiliary programming port can be used for UART communication, and the JTAG port for debugging\*.

<figure><img src="https://docs.microside.com/~gitbook/image?url=https%3A%2F%2F177299348-files.gitbook.io%2F%7E%2Ffiles%2Fv0%2Fb%2Fgitbook-x-prod.appspot.com%2Fo%2Fspaces%252FbyV2zAlQAiqg46a3Lr8z%252Fuploads%252FLfq6hu6NIEtrcAzLvo55%252Fuser-manual-u-p-pinout.jpg%3Falt%3Dmedia%26token%3D0a66778b-f008-467d-9a32-18a5305421cf&#x26;width=768&#x26;dpr=4&#x26;quality=100&#x26;sign=6a8c3925&#x26;sv=2" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
**Note on JTAG pins:** Enabling the pins for an external JTAG debugger requires *burning* the configuration fuse *STRAP\_JTAG\_SEL* and connecting GPIO 3 to GND. To re-enable USB debugging, connect GPIO 3 to 3.3V. Burning the *DIS\_USB\_JTAG* fuse will permanently disable USB debugging and enable external debugging. Please note that this change is permanent, so using the USB port for debugging is recommended.
{% endhint %}

{% hint style="danger" %}
**Warning!** The VCC pin on the auxiliary programming port is 3.3V. If the microcontroller is powered through the USB port or the mikroBUS interface (5V) **DO NOT** connect anything to the VCC pin. IO0, RST, TX0, and RX0 pins operate at 3.3V, use the correct voltage levels or you might damage the device.
{% endhint %}

## V. Setup and Usage

This X-NODE utilizes the ESP32-S3 module directly, making it possible to interact with its native pins and provide wireless connectivity to other X-NODEs or development boards through various communication protocols such as UART or I2C, you can program it using your preferred development environment.

Connect your **X-NODE MCU WIFI BLE (ESP32-S3)** to your computer via a USB Type-C cable and configure it depending on your operating system. The following examples use Windows.

{% hint style="warning" %}
If the module is **NOT** recognized, press the following sequence: Press Press BOOT button -> Press and Release RST button -> Release BOOT. After programming your device using this method, press the RST button to run the program.

Remember to enable CDC emulation on BOOT in your development environment to allow automatic programming and serial communication.
