This FeatherWing will make it easy to add data logging to any Feather Board you might have. You get both an I²C real-time clock (PCF8523) with 32 KHz crystal and battery backup, and a microSD socket that connects to the SPI port pins (+ extra pin for CS). Note: FeatherWing doesn't come with a microSD card. A CR1220 coin cell is required to use the RTC battery-backup capabilities. If you're not using the RTC part of the FeatherWing, a battery is not required. To talk to the microSD card socket Arduino's default SD library is recommended. Some light soldering is required to attach the headers onto the Wing. Pinouts Power pins On the bottom row, the 3.3 V (second from left) and GND (fourth from left) pin are used to power the SD card and RTC (to take a load off the coin cell battery when main power is available) RTC & I²C Pins In the top right, SDA (rightmost) and SCL (to the left of SDA) are used to talk to the RTC chip. SCL - I²C clock pin to connect to your microcontroller's I2C clock line. This pin has a 10 kΩ pull-up resistor to 3.3 V SDA - I²C data pin to connect to your microcontroller's I2C data line. This pin has a 10 kΩ pull-up resistor to 3.3 V There's also a breakout for INT which is the output pin from the RTC. It can be used as an interrupt output or it could also be used to generate a square wave. Note that this pin is an open drain - you must enable the internal pull-up on whatever digital pin it is connected to. SD & SPI Pins Starting from the left you've got SPI Clock (SCK) - output from feather to wing SPI Master Out Slave In (MOSI) - output from feather to wing SPI Master In Slave Out (MISO) - input from wing to feather These pins are in the same location on every Feather. They are used for communicating with the SD card. When the SD card is not inserted, these pins are completely free. MISO is tri-stated whenever the SD CS (chip select) pin is pulled high

The iCEBreaker FPGA board is an open-source educational FPGA development board. The iCEBreaker is great for classes and workshops teaching the use of the open source FPGA design flow through Yosys, nextpnr, IceStorm, Icarus Verilog, Amaranth HDL and others. This means the board is low cost and has a nice set of features to allow for the design of interesting classes and workshop exercises. At the same time it allows the user to use the proprietary vendor tools if they choose to. After the workshop the boards can be easily used as a development board as most GPIO are exposed, broken out and configurable through jumpers on the back of the board. There is only a minimal amount of buttons and LED that can't be disconnected and used for your own purposes. Documentation Workshop

Onboard each moto:bit are multiple I/O pins, as well as a vertical Qwiic connector, capable of hooking up servos, sensors and other circuits. At the flip of the switch, you can get your micro:bit moving! The moto:bit connects to the micro:bit via an updated SMD, edge connector at the top of the board, making setup easy. This creates a handy way to swap out micro:bits for programming while still providing reliable connections to all of the different pins on the micro:bit. We have also included a basic barrel jack on the moto:bit that is capable of providing power to anything you connect to the carrier board. Features More reliable Edge connector for easy use with the micro:bit Full H-Bridge for control of two motors Control servo motors Vertical Qwiic Connector I²C port for extending functionality Power and battery management onboard for the micro:bit

This book is about developing projects using the popular STM32CubeIDE software with the Nucleo-L476RG development board. In the early Chapters of the book the architecture of the Nucleo family is briefly described. The book covers many projects using most features of the Nucleo-L476RG development board where the full software listings for the STM32CubeIDE are given for each project together with extensive descriptions. The projects range from simple flashing LEDs to more complex projects using modules, devices, and libraries such as GPIO, ADC, DAC, I²C, SPI, LCD, DMA, analogue inputs, power management, X-CUBE-MEMS1 library, DEBUGGING, and others. In addition, several projects are given using the popular Nucleo Expansion Boards. These Expansion Boards plug on top of the Nucleo development boards and provide sensors, relays, accelerometers, gyroscopes, Wi-Fi, and many others. Using an expansion board together with the X-CUBE-MEMS1 library simplifies the task of project development considerably. All the projects in the book have been tested and are working. The following sub-headings are given for each project: Project Title, Description, Aim, Block Diagram, Circuit Diagram, and Program Listing for the STM32CubeIDE. In this book you will learn about STM32 microcontroller architecture; the Nucleo-L476RG development board in projects using the STM32CubeIDE integrated software development tool; external and internal interrupts and DMA; DEBUG, a program developed using the STM32CubeIDE; the MCU in Sleep, Stop, and in Standby modes; Nucleo Expansion Boards with the Nucleo development boards.

The Power Delivery Board uses a standalone controller to negotiate with the power adapters and switch to a higher voltage other than just 5V. This uses the same power adapter for different projects rather than relying on multiple power adapters to provide different output; it can deliver the board as part of SparkFun’s Qwiic connect system, so you won’t have to do any soldering to figure out how things are oriented. The SparkFun Power Delivery Board takes advantage of the power delivery standard using a standalone controller from STMicroelectronics, the STUSB4500. The STUSB4500 is a USB power delivery controller that addresses sink devices. It implements a proprietary algorithm to negotiate a power delivery contract with a source (i.e. a power delivery wall wart or power adapter) without the need for an external microcontroller. However, you will need a microcontroller to configure the board. PDO profiles are configured in an integrated non-volatile memory. The controller does all the heavy lifting of power negotiation and provides an easy way to configure over I²C. To configure the board, you will need an I²C bus. The Qwiic system makes it easy to connect the Power Delivery board to a microcontroller. Depending on your application, you can also connect to the I²C bus via the plated through SDA and SCL holes. Features Input and output voltage range of 5-20V Output current up to 5A Three configurable power delivery profiles Auto-run Type-C™ and USB PD sink controller Certified USB Type-C™ rev 1.2 and USB PD rev 2.0 (TID #1000133) Integrated VBUS voltage monitoring Integrated VBUS switch gate drivers (PMOS)
