Wide Range Power Supply for Raspberry Pi
With the PiEnergy Mini, you can operate your Raspberry Pi with a voltage of 6 to 36 V DC. You can use the button integrated on the board to both power up and power down your Raspberry Pi.
Communication with the Raspberry Pi is via GPIO4, but this connection can also be cut by removing a resistor to use the pin freely. Thanks to the ultra-flat design, it can also be used in many housings. The pin header is included and not soldered on to keep the design even flatter.

The Uno R3 board is the perfect microcontroller for those who want to enter the programming world without any fuss. Its ATMega328 microcontroller provides you with enough power for your ideas and projects. The Uno board has a USB type B connector so that you can easily use it with programs – of course via the well-known programming environment Arduino IDE. You can connect it to the power source via the USB port or alternatively use its own power connection. Please note: The CH341 driver must be installed beforehand so that Uno board is recognized by the Arduino IDE.

This JOY-iT microcontroller board opens the world of programming to you and offers you the same computing power as the Mega 2560, but with a smaller foot-print. It also has many more connectors than comparable boards (Arduino Uno). It is powered by the Arduino IDE and power can be supplied either via the USB port or the VIN pins. This allows you to use it safely with many other devices, e.g. desktop PC. Therefore the Mega 2560 Pro is highly integrable.

35 Touch Develop & MicroPython Projects
The BBC micro:bit is a credit sized computer based on a highly popular and high performance ARM processor. The device is designed by a group of 29 partners for use in computer education in the UK and will be given free of charge to every secondary school student in the UK.
The device is based on the Cortex-M0 processor and it measures 4 x 5 cm. It includes several important sensors and modules such as an accelerometer, magnetometer, 25 LEDs, 2 programmable push-button switches, Bluetooth connectivity, micro USB socket, 5 ring type connectors, and a 23-pin edge connector. The device can be powered from its micro USB port by connecting it to a PC, or two external AAA type batteries can be used.
This book is about the use of the BBC micro:bit computer in practical projects. The BBC micro:bit computer can be programmed using several different programming languages, such as Microsoft Block Editor, Microsoft Touch Develop, MicroPython, and JavaScript.
The book makes a brief introduction to the Touch Develop programming language and the MicroPython programming language. It then gives 35 example working and tested projects using these language. Readers who learn to program in Touch Develop and MicroPython should find it very easy to program using the Block Editor or any other languages.
The following are given for each project:
Title of the project
Description of the project
Aim of the project
Touch Develop and MicroPython program listings
Complete program listings are given for each project. In addition, working principles of the projects are described briefly in each section. Readers are encouraged to go through the projects in the order given in the book.
The Motorino board is an extension-board to control and use up to 16 PWM-controlled 5V-Servo-motors. The included clock generator ensures a very precise PWM signal and a very precise positioning. The board has 2 inputs for voltage from 4.8 V to 6 V which can be used for up to 11 A. With this input, a perfect power supply is always guaranteed and even bigger projects are no problem. The supply runs directly over the Motorino which provides a connection for voltage, ground and control. With the build in capacitor, the voltage is buffered which prevents a sudden voltage-drop at a high load. But there is also the possibility to connect another capacitor. The control and the programing can be done, as usual, with the Arduino. Manuals and code examples allows a quick introduction for beginners.

The Unitree G1 is a modern humanoid robot that impresses with its remarkable flexibility and advanced technology. With an exceptionally wide range of joint movement and up to 43 joint motors, it exceeds the agility of a typical human. Powered by imitation learning and reinforcement learning, its robotic systems are continuously developed and optimized through artificial intelligence.
One of the G1's most impressive features is its ability to autonomously move into a walking position as soon as it touches the ground – no external assistance required! It can immediately start moving, demonstrating a high level of independence and adaptability. The G1 is also equipped with a force-controlled, highly dexterous hand that operates with both sensitivity and precision, thanks to its combination of force and position control. This hand closely mimics human movements, allowing for precise object manipulation.

The MotoPi is an extension-board to control and use up to 16 PWM-controlled 5 V servo motors. The board can be additional powered by a voltage between 4.8 V and 6 V so a perfect supply is always guaranteed and even larger projects can be powered. With the additional power supply and the integrated Analog-Digital-Converter, new possibilities can be reached. An additional power supply per motor is not required anymore because all connections (Voltage, Ground, Control) are directly connected to the board. The control and the programing can be directly done, as usual, on the Raspberry Pi. Special features 16 Channels, own clock generator, Inkl.
