Wireless IoT Project Development with the ESP32
The ESP32 represents a low-cost, low-power System-on-Chip (SoC) microcontroller with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series utilizes either a Tensilica Xtensa LX6 microprocessor in dual-core and single-core variations, Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.
The ESP32 is created and developed by Espressif Systems, a Shanghai-based Chinese company, and manufactured by TSMC. It is a successor to the ESP8266 microcontroller.
Developing IoT Projects with ESP32 presents an end-to-end coverage of secure data communication techniques from sensors to cloud platforms that will assist the reader in creating production-grade IoT solutions with the ESP32 SoC. In addition, the reader will learn how to engage the ESP32 in your IoT projects by interfacing with different sensors and actuators using various types of serial protocols.
The book shows how several projects demand immediate output for end-users, including different display technologies and examples of driving different types of displays. Furthermore, the book features a dedicated chapter on cybersecurity filled with various hands-on examples.
It also covers BLE technologies and BLE mesh networking and documents a complete intelligent home project where all nodes communicate over a BLE mesh. Later chapters demonstrate how IoT requires cloud connectivity and remote access to smart devices. Finally, the book explains how cloud platforms and third-party integrations support unlimited opportunities for end-users, such as insights with big data analytics and predictive maintenance to reduce operating costs.
At the end of this book, the reader has the skills they need to start using ESP32 in their wireless IoT project and meet the project's requirements by developing practical, effective, and secure solutions.
ESP32 WiFi, Bluetooth Classic, BLE, CAN Bus Module
This new ESP32 CAN Bus module implements all features required for an industrial-strength CAN Bus, SAE J1939, or NMEA2000 gateway.
The board comes with an onboard ESP32 WROOM-32 WiFi, Bluetooth Classic, BLE Module, and a CAN Bus port with a transceiver. Also, onboard is an RGB LED, IO pins on a 0.1" pad.
In addition to the onboard CAN-Bus port, it supports an extended temperature range of -40C to + 85C, and it accepts a wide range of power input, 4.5VDC to 46VDC. The power input range is vital for operating on diesel engines using an SAE J1939 or NMEA2000 network, where power fluctuation is typical.
