Overview of this book

As an embedded systems developer or an IoT developer, you can often face challenges in maintaining focus on prototyping a product concept while using a specific high-level programming language for implementation. To overcome these challenges, the M5Stack Core platform uses an ESP32 microcontroller and block code that allows you to focus on product creation and application instead of the high-level programming language. M5Stack Electronics Blueprints presents various design and prototyping approaches as well as UI layout and electronics interfacing techniques that will help you to become skilled in developing useful products effectively. This book takes you through a hands-on journey for a better understanding of the ESP32 microcontroller and the M5Stack Core's architecture. You’ll delve into M5Stack Core topics such as electronic units, light, sound, motion devices, interfacing circuits, SNAP circuit kits, Arduino applications, and building Bluetooth and Wi-Fi IoT devices. Further, you’ll explore various M5Stack core applications using a project-based learning method, including the fascinating 32-bit microcontroller device technology. By the end of this book, you’ll be able to design and build interactive, portable electronic controllers, IoT, and wearable devices using the M5Stack Core.

An introduction to Wi-Fi with the ESP32

The M5Stack Core ESP32 microcontroller’s Wi-Fi system architecture consists of two subsystems: Wi-Fi media access control (MAC) and the baseband. The Wi-Fi MAC address is a unique identifier that is assigned to a network interface controller (NIC). The NIC allows us to address the network used in the Wi-Fi-based communication system. The MAC address for the M5Stack Core controller is shown in Figure 8.1:

The Wi-Fi baseband in a communication system is the modulating signal or intelligence sent through a single channel. The intelligence or digital data stream is sent through as the information through a single channel media. Wi-Fi baseband communication uses bidirectional communication transmitted through the single channel media to send and receive digital data. Figure 8.2 illustrates the ESP32 communication system block diagram.
