ESP32 WROOM
DEVELOPMENT BOARD

The ESP32 is an easy to use
MCU that includes WiFi, BlueTooth LE
and Peripherals all in one module

Seven Segment LED Overview

The ESP32 Development Board is a board created around ESP32 WROOM 32 chip
containing voltage regulator and USB programmer circuit for ESP32 chip,
and a few many other features. For application development there is a choice
between Arduino IDE or ESP-IDF (Native platform). Mostly users choose
the Arduino IDE because of its simplicity and compatibility. ESP32
Development Board comes with a pre-installed firmware which allows to work
with the interpreted language, sending commands through the serial port
(CP2102 USB to Serial chip). The ESP32 Development board is specially
designed to work on breadboard. It has a voltage regulator that allows it
to feed directly from the USB port. The input/output pins work at 3.3V.
The CP2102 chip is responsible for USB to serial communication.

MCU + Wifi + BLE

The board functions as a 32 MCU and provides all peripherals expected
from an MCU. It also includes a Wifi transceiver unit and a BLE 4.2 Radio.
All of this functionality is easily accessed through the Arduino IDE. An
easy to use, intuitive software interface to build your software programs
such as Weather Station, Indoor Asset Tracking, Robotics and much more.

Programming The ESP32 MCUs

Programming the ESP32 with User Software is easy using the Arduino IDE.
The ESP32 WROOM Development board includes a USB to Serial chip. Just
connect the board to an open USB Port on your PC using a Micro-B cable.
Then open the Arduino IDE software, select the board from the library.
Write your software, then hit the "Upload" button. It's as easy as that.

When the ESP WROOM Development Board is connected to an open USB Port
the USB driver for the CP2109 chip is loaded. You will be able to see this
chip under "Device Manager" as a COM Port. Once the ESP32 board appears as a
COM Port, the Arduino IDE will be able to connect to it.

Connecting the Arduino IDE to ESP32

Once the ESP32 board is connected and the driver is loaded, Open the
Arduino IDE, then click on the "Boards Manager" button and search the left
side of the Window for the ESP32 Libraries. Click on "Install" and the software
will automatically install all the available libraries for several ESP32 Development
boards.

Once all the ESP32 libraries are installed, you can go Tools->Board
and select the "ESP32 Dev Module". Then go to Tools->Port and select the
COM Port that the ESP32 WROOM Development board is attached to. With these
items selected, you can now write and execute your own code.

The User Manual will show to the user how select one of the pre-compiled
sample programs and load it, compile it and upload it to the ESP32 MCU.
The User Manual will show the user how to build the projects using a bread
board, ESP32 WROOM Development Board, Wire Kit and Device (Such as LED RGB.
Breakout Board or Seven Segment LED Display Board).

ESP32 Code Development

With your first programmed loaded and working on to the ESP32 WROOM
Development Board completed, you can start on more advanced projects.
More advanced projects will include getting started with WiFi. There
are several pre-compiled WiFi projects under the Arduino ESP32 Examples.
These examples are easy to use. Just open the sketch, upload and start
examining the results.
The ESP32 WROOM Development Board is a complete Development Kit that is
easy to get started, easy to develop code and easy to get advanced projects
perfected. This kit is great for beginners, great for intermediate programmers,
and great for advanced projects.
