M5Stack Electronic Blueprints

By: Don Wilcher

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.

The ESP32 microcontroller Bluetooth chipset

The M5Stack Core2 uses an ESP32-DOWDQ6-V3 microcontroller incorporating a 240 MHz, dual-core microprocessor. A dual-core microprocessor provides efficiency in computation and managing input/output (I/O) operations of the microchip using two central processing units (CPUs). Within this family of ESP32 microcontrollers, the chip has a Bluetooth chipset consisting of a link controller and baseband. The Bluetooth link controller handles the physical layer packets and all communication timing. The link controller implements the link, the low-level real-time protocol that operates Bluetooth communications. The baseband is the physical layer of Bluetooth communications. The baseband manages physical channels and uses other services in communication such as security and error correction. The baseband protocol or operating rule performs the link controller within the Bluetooth chipset. Figure 7.1 illustrates the Bluetooth chipset architecture:
