What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

Disclaimer: I was given an early review copy of this book and did not purchase it.TLDR: Loved the book, definitely keeping it nearby while developing IoT projects This book does a fantastic job on many fronts:- succinctly highlighting details about the ESP32 family- thorough explanations on build setup (a major pain in many projects)- thorough code snippets that include full configuration parameters, making it a great reference- introducing first and third-party libraries that would cover a majority of needs (file systems, json, etc).- demonstrating projects of different scales, increasing the scope in large but exciting steps.- including sections on cloud integrations and ML- emphasizing different aspects of security in well-placed chunksComments:- I was really hoping to see sections involving bluetooth or LoRa- I like that the book used devices with both Xtensa and RISC-V architecturesIf I were to characterize the readers that would benefit most from this book, it would be Advanced Beginners in embedded projects. Programmers from other domains that are interested in IoT, engineering students, hobbyists that have already dabbled in microcontrollers, anyone in the "Ok, I can flash firmware and blink an LED, what's next?" phase or above.

When I started my journey with the ESP32 the first edition of this book was the go to reference for everyone. Everywhere I looked to find guidance on how to begin with this awesome platform I was met with a clear "go read Vedat's book". The new second edition has improved on that reverential text in many ways. The examples are relevant, clear, and concise. The demonstration hardware was out of stock while I was reviewing the book but comparable kits are all over the place; if you know what to look for.And that is the rub, like the first edition before it this book assumes a level of familiarity with coding and microcontrollers you won't likely have if it is your first time. And while the first edition dominated the landscape because there were no beginner friendly alternatives, now we have a plethora of choices for all levels of experience. So, who is this book for?If you are just getting started in microcontrollers with no or very little coding experience, I suggest you start with Arduino. There are many websites and books devoted to you.If you are already comfortable in embedded C/C++ this book may be interesting but honestly you will probably get more value out of the Espressif IDF online documentation, it is fantastic.For C++ developers who have never played with a microcontroller before this book is exactly where you should begin. You will get elegant step by step guidance through the basic applications of the ESP32 using modern code structures.If you are not comfortable with C++, this book could be great as your first experience in microcontrollers as long as you take the time to work through the additional reference texts provided by the author. It will be a lot of work, but very fulfilling when you see the device light up for the first time. It is a magical feeling.Over all, highly recommended, as long as it is to the right audience.

The book has been great so far; I’m just wrapping up Chapter 3. It covers everything you need to know about debugging, wiring, different IDEs—pretty much all the details to dive into the ESP32 world. Note that some libraries and code require updates since the book was published, but there’s an updated branch on the official GitHub page with the latest revisions. Additionally, you can easily use the ESP32-S3-Box-3, which is widely available, instead of the Box-3 Lite, as the newest updates were made for this device.

Diane J Dec 12, 2023

Pretty good Professional ESP32 Developer Resources, a lot of information in one place.Great examples with C++ programming and Espressif tools.This is NOT a Hobby / Maker book, don't look for an Arduino IDE with simple 101 Examples this book contains a true Pro Level information to make a Real Product.This book contains a Kitchen Sink full of examples to connect to all sorts of devices, make network calls, Blue Tooth, WiFi, etc. A great Reference as well.Overall this is a great book, lots of good information for someone wanting to be a Professional Developer and who has basic C/C++ knowledge. I highly recommend this book for anyone using the ESP32 chip and building a product.

This book is an introduction to the exciting world of the Internet of Things (IoT) and the ESP32 ecosystem. It includes many practical labs that you can do. The author bought an ESP32 SX1262 for $28 on Amazon to do the labs in the book and found the instructions to be very accurate. The book starts with the basics of the platform and then covers development tools. After that, it's all about hands-on learning. By the end of the book, you will have built an audio player, learned how to use WIFI for connectivity and communication with cloud services, used ESP32 for security, and completed several other projects. If you want to create smart devices for production environments, this book is for you.
