Thanks to its I²C capabilities, this PWM HAT saves the Raspberry Pi's GPIO pins, allowing you to use them for other purposes. The Servo pHAT also adds a serial terminal connection, which will allow you to bring up a Raspberry Pi without having to hook it up to a monitor and keyboard. We have provided a Qwiic connector for easy interfacing with the I²C bus using the Qwiic system and a 4-pin header to connect to the Sphero RVR. Power to the SparkFun Servo pHAT can be supplied through a USB-C connector. This will power either the servo motors only or power the servo motors and the Raspberry Pi that is connected to the HAT. We switched to USB-C to allow you to bring more current to your servos than ever before. This USB-C connector can also hook up the Pi via serial port connection to avoid having to use a monitor and keyboard for setting up the Pi. To supply power only to the servo power rail (and not the Pi's 5V power rail), you need to cut a small trace on the isolation jumper. Doing this allows you to drive heavier loads coming from multiple or larger servos. We've even added power protection circuits to the design to avoid damage to power sources. Each of this pHAT's 16 servo motor pin headers has been spaced out to the standard 3-pin servo pinout (ground, 5V, signal) to make it easier to attach your servo motors. The Servo pHAT is the same size and form factor as a Raspberry Pi Zero and Zero W, but it can also operate with a regular Raspberry Pi.

The SparkFun Thing Plus Matter is the first easily accessible board of its kind that combines Matter and SparkFun’s Qwiic ecosystem for agile development and prototyping of Matter-based IoT devices. The MGM240P wireless module from Silicon Labs provides secure connectivity for both 802.15.4 with Mesh communication (Thread) and Bluetooth Low Energy 5.3 protocols. The module comes ready for integration into Silicon Labs' Matter IoT protocol for home automation.
What is Matter? Simply put, Matter allows for consistent operation between smart home devices and IoT platforms without an Internet connection, even from different providers. In doing so, Matter is able to communicate between major IoT ecosystems in order to create a single wireless protocol that is easy, reliable, and secure to use.
The Thing Plus Matter (MGM240P) includes Qwiic and LiPo battery connectors, and multiple GPIO pins capable of complete multiplexing through software. The board also features the MCP73831 single-cell LiPo charger as well as the MAX17048 fuel gauge to charge and monitor a connected battery. Lastly, a µSD card slot for any external memory needs is integrated.
The MGM240P wireless module is built around the EFR32MG24 Wireless SoC with a 32-bit ARM Cortext-M33 core processor running at 39 MHz with 1536 kb Flash memory and 256 kb RAM. The MGM240P works with common 802.15.4 wireless protocols (Matter, ZigBee, and OpenThread) as well as Bluetooth Low Energy 5.3. The MGM240P supports Silicon Labs' Secure Vault for Thread applications.

Create Models for 3D Printing, CNC Milling, Process Communication and Documentation
Engineers dread designing 3D models using traditional modeling software. OpenSCAD takes a refreshing and completely different approach. Create your models by arranging geometric solids in a JavaScript-like language, and use them with your 3D printer, CNC mill, or process communication.
OpenSCAD differs from other design systems in that it uses programmatical modeling. Your model is made up of primitives that are invoked using a C-, Java- or Python-like language. This approach to model design is close to the “mechanical work” done in the real world and appeals to engineers and others who are not a member of the traditional creative class.
OpenSCAD also provides a wide variety of comfort functions that break the 1:1 relationship between code and geometry. This book demonstrates the various features of the programming language using practical examples such as a replacement knob for a LeCroy oscilloscope, a wardrobe hanger, a container for soap dispensers, and various other real-life examples.
Written by an engineer with over 15 years of experience, this book is intended for Linux and Windows users alike. If you have programming experience in any language, this book will have you producing practical three-dimensional objects in short order!

An illustrated chronicle of Teknology for collectors and restorers
Oscilloscopes have made a major contribution to the advancement of human knowledge, not only in electronics, but in all sciences, whenever a physical quantity can be converted into a timerelated electrical signal.
This book traces the history of a crucial instrument through many Tektronix products. This is the company that invented and patented most of the functions found in all oscilloscopes today. Tek is and will always be synonymous with the oscilloscope.
In nearly 600 pages, with hundreds of gorgeous photos, diagrams, anecdotes, and technical data, you'll travel through the history of Tektronix in a superb collector's edition with a technical point of view. The author is not afraid to get his hands dirty restoring his own Tek equipment. The journey starts in the early 1950s. It ends in the '90s, after exploring the ins and outs of the most interesting models in the 300, 400, 500, 5000, 7000, and 11000 series, from tubes to advanced hybrid technologies.

An Illustrated Handbook of Vintage ‘Scopes Repair and Preservation
Tektronix oscilloscopes are true masterpieces of electronics and have helped mankind advance in every field of science, wherever a physical phenomenon needed to be observed and studied. They helped man reach the moon, find the cause of plane crashes, and paved the way for thousands of other discoveries.
Restoring and collecting these oscilloscopes is an exciting activity; it is really worthwhile to save them from the effects of time and restore them to their original condition. Many parts are quite easy to find, and there are many Internet sites, groups, and videos that can help you. Much of the original documentation is still available, but it is not always sufficient. This book contains a lot of information, descriptions, suggestions, technical notes, photos and schematics that can be of great help to those who want to restore or simply repair these wonderful witnesses of one of the most beautiful eras in the history of technology.
Component layouts included!
This book includes a nearly complete component layout plan of the original 545 oscilloscope, with relative reference designators. Not found in the original Tektronix manuals, this layout should prove invaluable to the repair technician.
