1. ESP - WROOM - 32 is a small form factor ( SFF ) 802.11 b / g / n / e / i ( 2.4GHz ) WLAN plus BT4.2 combo solution which is optimized for low-power and wearable Internet of Things devices. 2. ESP - WROOM - 32 integrates all WLAN and BT functionality in a single package to support a low-cost, layout-friendly implementation while allowing flexibility for platform specific customization. 3. ESP - WROOM - 32 is a highly integrated solution with less than 10 external components. 4. The entire solution reduces Printed Circuit Board ( PCB ) area, time-to-market, and bill-of-material ( BOM ) costs while adding capabilities and processing power. 5. An optimal balance between the communication range, data rate, and power consumption is achieved with fine granularity clock-gating, multiple low-power modes, and dynamic voltage scaling. 6. Applications: audio and video, OTT devices, smart devices, home automation, industrial automation, healthcare, development support, etc.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
