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.

M5Stack Core2 touchscreen UI controls introduction

The M5Stack Core2 is an enhanced version of the original Core unit. As with the original Core unit, the Core2 uses an ESP32-based microcontroller for providing internal hardware components such as the RGB bars, speaker, microphone, gyro, and accelerometers. An internal vibration motor is included with the M5Stack Coe2 unit. The M5Stack Core2 uses a specialized IC to operate a capacitive touchscreen. The touchscreen is overlayed with a Thin Film Transistor (TFT) LCD. Figure 6.1 shows a conceptual diagram of the M5Stack Core2’s touchscreen assembly. As shown in the conceptual diagram, the specialized IC is a touchscreen controller responsible for touch detection and processing of a human finger:
