Contents Basic principles A connector is an electromechanical system that provides a separable connection between two subsystems of an electronic device without an unacceptable effect on the performance of the device. It will be shown that there are a lot of complex parameters to handle properly to make this statement true. Design / Selection / Assembly This chapter provides an overview of design and material requirements for contact finishes, contact springs and connector housings as well as the major degradation mechanisms for these connector components. To complete this chapter, material selection criteria for each will also be reviewed. Additionally the Level of Interconnection (LOI) was integrated into this chapter as it addresses, where the connector is used within an electronic system and therefore influences the requirements and durability of the connector depending on its use. Applications This chapter is heading to the practical work and shows how customers use connectors in their applications to offer some possibilities and to ease your daily work. Additionally it contains some special topics like tin-whisker or impedance of ZIF cable to offer you extended background knowledge.

Based on PIC microcontrollers and Arduino
Every mobile phone includes a GSM/GPRS modem which enables the phone to communicate with the external world. With the help of the GSM modems, users can establish audio conversations and send and receive SMS text messages. In addition, the GPRS modem enables users to connect to the internet and to send and receive large files such as pictures and video over the internet.
This book is aimed for the people who may want to learn how to use the GSM/GPRS modems in microcontroller based projects. Two types of popular microcontroller families are considered in the e-book: PIC microcontrollers, and the Arduino. The highly popular mid-performance PIC18F87J50 microcontroller is used in PIC based projects together with a GSM Click board. In addition, the SIM900 GSM/GPRS shield is used with the Arduino Uno projects. Both GSM and GPRS based projects are included in the e-book.
The book will enable you to control equipment remotely by sending SMS messages from your mobile phone to the microcontroller, send the ambient temperature readings from the microcontroller to a mobile phone as SMS messages, use the GPRS commands to access the internet from a microcontroller, send temperature readings to the cloud using UDP and TCP protocols and so on.
It is assumed that the reader has some basic working knowledge of the C language and the use of microcontrollers in simple projects. Although not necessary, knowledge of at least one member of the PIC microcontroller family and the Arduino Uno will be an advantage. It will also be useful if the user has some knowledge of basic electronics.

This small mono amplifier is surprisingly powerful – able to deliver up to 2.5 W into 4-8 Ω impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0-5.5 V DC. Since the amplifier is a class D, it's very efficient making it perfect for portable and battery-powered projects. It has built-in thermal and over-current protection. There's even a volume trim pot so you can adjust the volume on the board down from the default 24 dB gain.
The A+ and A- inputs of the amplifier go through 1.0 µF capacitors, so they are fully 'differential' – if you don't have differential outputs, simply tie the Audio-pin to ground. The output is 'Bridge Tied' – that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250 KHz square wave PWM that is then 'averaged out' by the speaker coil – the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly.
The amplifier comes with a fully assembled and tested breakout board, a header to plug it into a breadboard and a 3.5 mm screw-terminal blocks so you can easily attach/detach your speaker. Speaker is not included, we recommend using any 4 Ω or greater impedance speaker.
Features
Output Power: 2.5 W at 4 Ω, 10% THD (total harmonic distortion), 1.5 W at 8 Ω, 10% THD, with 5.5 V Supply
50 dB PSRR (power supply rejection ratio) at 1 KHz
Filterless design, with ferrite bead + capacitors on output.
Fixed 24 dB gain, an onboard trim potentiometer for adjusting input volume.
Thermal and short-circuit/over-current protection
Low current draw: 4 mA quiescent and 0.5 mA in shutdown (due to pull-up resistor on SD pin)

All necessary hardware is included.
The pan-tilt base is attached directly to an Arduino with Arduino-compatible hole-pattern and includes stand-offs and fasteners.
Several pan-tilt demos are provided that can run using either Arduino, Raspberry Pi or stand-alone (no controller).

ARM Cortex-M Embedded Design from 0 to 1
Hobbyists can mash together amazing functional systems using platforms like Arduino or Raspberry Pi, but it is imperative that engineers and product designers understand the foundational knowledge of embedded design. There are very few resources available that describe the thinking, strategies, and processes to take an idea through hardware design and low-level driver development, and successfully build a complete embedded system. Many engineers end up learning the hard way, or never really learn at all.
ARM processors are essentially ubiquitous in embedded systems. Design engineers building novel devices must understand the fundamentals of these systems and be able to break down large, complicated ideas into manageable pieces. Successful product development means traversing a huge amount of documentation to understand how to accomplish what you need, then put everything together to create a robust system that will reliably operate and be maintainable for years to come.
This book is a case study in embedded design including discussion of the hardware, processor initialization, low‑level driver development, and application interface design for a product. Though we describe this through a specific application of a Cortex-M3 development board, our mission is to help the reader build foundational skills critical to being an excellent product developer. The completed development board is available to maximize the impact of this book, and the working platform that you create can then be used as a base for further development and learning.
The Embedded in Embedded program is about teaching fundamental skill sets to help engineers build a solid foundation of knowledge that can be applied in any design environment. With nearly 20 years of experience in the industry, the author communicates the critical skill development that is demanded by companies and essential to successful design. This book is as much about building a great design process, critical thinking, and even social considerations important to developers as it is about technical hardware and firmware design.
