This 900 MHz radio version can be used for either 868 MHz or 915 MHz transmission/reception – the exact radio frequency is determined when you load the software since it can be tuned around dynamically. At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3 V logic. This chip has 32 K of flash and 2 K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc. To make it easy to use for portable projects, we added a connector for any 3.7 V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge. Features Measures 2.0' x 0.9' x 0.28' (51 x 23 x 8 mm) without headers soldered in Light as a (large?) feather – 5.5 grams ATmega32u4 @ 8 MHz with 3.3 V logic/power 3.3 V regulator with 500 mA peak current output USB native support, comes with USB bootloader and serial port debugging You also get tons of pins – 20 GPIO pins Hardware Serial, hardware I²C, hardware SPI support 7x PWM pins 10x analog inputs Built in 100 mA lipoly charger with charging status indicator LED Pin #13 red LED for general purpose blinking Power/enable pin 4 mounting holes Reset button The Feather 32u4 Radio uses the extra space left over to add an RFM69HCW 868/915 MHz radio module.

Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar – Adafruit uses the technique on all thier native-USB boards. Just note you don't double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support – so if you're doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you'll get close-to-M4 speeds!For peripherals, there are two I²C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO – check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).Technical Specifications Measures 2.0 x 0.9 x 0.28' (50.8 x 22.8 x 7 mm) without headers soldered in Light as a (large?) feather – 5 grams RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3 V logic and power 264 KB RAM 8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage. No EEPROM Tons of GPIO! 21 x GPIO pins with following capabilities: Four 12 bit ADCs (one more than Pico) Two I²C, Two SPI and two UART peripherals, one is labeled for the 'main' interface in standard Feather locations 16 x PWM outputs - for servos, LEDs, etc The 8 digital 'non-ADC/non-peripheral' GPIO are consecutive for maximum PIO compatibility Built in 200 mA+ lipoly charger with charging status indicator LED Pin #13 red LED for general purpose blinking RGB NeoPixel for full color indication. On-board STEMMA QT connector that lets you quickly connect any Qwiic, STEMMA QT or Grove I²C devices with no soldering! Both Reset button and Bootloader select button for quick restarts (no unplugging-replugging to relaunch code) 3.3 V Power/enable pin Optional SWD debug port can be soldered in for debug access 4 mounting holes 24 MHz crystal for perfect timing. 3.3 V regulator with 500mA peak current output USB Type C connector lets you access built-in ROM USB bootloader and serial port debugging RP2040 Chip Features Dual ARM Cortex-M0+ @ 133 MHz 264 kB on-chip SRAM in six independent banks Support for up to 16 MB of off-chip Flash memory via dedicated QSPI bus DMA controller Fully-connected AHB crossbar Interpolator and integer divider peripherals On-chip programmable LDO to generate core voltage 2 on-chip PLLs to generate USB and core clocks 30 GPIO pins, 4 of which can be used as analog inputs Peripherals 2 UARTs 2 SPI controllers 2 I²C controllers 16 PWM channels USB 1.1 controller and PHY, with host and device support 8 PIO state machines Comes fully assembled and tested, with the UF2 USB bootloader.

Is your house haunted? Or, rather, are you convinced that your house is haunted but have never been able to prove it since you've never had a camera that integrated with your Raspberry Pi Zero but was still small enough that the ghosts wouldn't notice it? Luckily, the spy camera for Raspberry Pi Zero is smaller than a thumbnail with a high enough resolution to see people, ghosts, or whatever it is you're looking for. It's about the size of a cell phone camera – the module being just 8.6 x 8.6 mm – with only a 2' cable, so you can create an extra compact and sneaky little spy cam. It has a 160-degree focal angle for a very wide/distorted fisheye effect that's great for security systems or watching a big swath of the living room or roadway. Like the Raspberry Pi camera board, it attaches to your Raspberry Pi Zero v1.3 or Zero W by way of the small socket on the board's edge closest to the 'PWR in' port. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data. The camera is connected to the BCM2835 processor on the RPi via the CSI bus, a higher bandwidth link which carries pixel data from the camera back to the processor. This bus travels along the ribbon cable that attaches the camera board to the Pi. The ribbon cables are compatible with both the RPi Zero v1.3 and RPi Zero W. The sensor itself has a native resolution of 5 megapixels and has a fixed focus lens onboard. It has similar specs as the original RPi camera, but is not as high-res as the new RPi camera v2! Specifications Camera Module Dimensions: 8.6 x 8.6 mm Lens Diameter: 10 mm Total Length: 60 mm Lens Focal Angle: 160 degrees Weight: 1.9 g

If you enjoy DIY electronics, projects, software and robots, you’ll find this book intellectually stimulating and immediately useful. With the right parts and a little guidance, you can build robot systems that suit your needs more than overpriced commercial systems can. 20 years ago, robots based on simple 8-bit processors and touch sensors were the norm. Now, it’s possible to build multi-core robots that can react to their surroundings with intelligence. Today’s robots combine sensor readings from accelerometers, gyroscopes and computer vision sensors to learn about their environments. They can respond using sophisticated control algorithms and they can process data both locally and in the cloud. This book, which covers the theory and best practices associated with advanced robot technologies, was written to help roboticists, whether amateur hobbyist or professional, take their designs to the next level. As will be seen, building advanced applications does not require extremely costly robot technology. All that is needed is simply the knowledge of which technologies are out there and how best to use each of them. Each chapter in this book will introduce one of these different technologies and discuss how best to use it in a robotics application. On the hardware side, we’ll cover microcontrollers, servos, and sensors, hopefully inspiring you to design your own awe-inspiring, next-generation systems. On the software side, we’ll cover programming languages, debugging, algorithms, and state machines. We’ll focus on the Arduino, the Parallax Propeller, Revolution Education PICAXE and projects I’ve with which I’ve been involved, including the TBot educational robot, the PropScope oscilloscope, the 12Blocks visual programming language, and the ViewPort development environment. In addition, we’ll serve up a comprehensive introduction to a variety of essential topics, including output (e.g. LEDs, servo motors), and communication technologies (e.g. infrared, audio), that you can use to develop systems that interact to stimuli and communicate with humans and other robots. To make these topics as accessible as possible, handy schematics, sample code and practical tips regarding building and debugging have been included. Hanno Sander Christchurch, New Zealand

This book is intended for electronics enthusiasts and professionals alike, who want a much deeper understanding of the incredible technology conquests over the pre-digital decades that created video. It details evolution of analogue video electronics and technology from the first electro-mechanical television, through advancements in Cathode Ray Tubes, transistor circuits and signal processing, up to the latest analogue, colour-rich TV, entertainment devices and calibration equipment. Key technological advances that enabled monochrome video and, eventually, colour are explained. The importance, compromises and techniques of maintaining crucial backward legacy compatibilities are described. The generation, signal processing and playback of analogue video signals in numerous capture, display, recording and playback devices together with operating principles and practices are examined. Technical and, often, political merits and deficiencies of key national and international video standards are highlighted. Several formats are shown to win and ultimately to co-exist. This book begins at fairly basic levels; concepts are introduced with human physiological perceptions of light and colour explained. This leads to the subject matter of luminance and chrominance; their equations and the circuits to process. There is full, detailed analysis of waveform shapes and timings inside video equipment and relevant popular connections e.g. S-video. Several analogue video projects which you can build yourself are also included in this book; with schematics, circuit board layouts and calibration steps to help you obtain the best results. The book makes use of many colour pages where the subject matter demands it (e.g. test cards). If you really want a deeper understanding of analogue video then this book is for you!

The MKR IoT Carrier comes equipped with 5 RGB LEDs, 5 capacitive touch buttons, a colored display, IMU and a variety of quality sensors. It also features a battery holder for a 18650 Li-Ion battery, SD card holder and Grove connectors. Data Capture: Map the environment around the carrier using the integrated temperature, humidity, and pressure sensors and collect data about movement using the 6 axis IMU and light, gesture, and proximity sensors. Easily add more external sensors to capture more data from more sources via the on-board Grove connectors (x3). Data Storage: Capture and store all the data locally on an SD card, or connect to the Arduino IoT Cloud for real-time data capture, storage, and visualization. Data Visualisation: Locally view real-time sensor readings on the built-in OLED Color Display and create visual or sound prompts using the embedded LEDs and buzzer. Total Control: Directly control small-voltage electronic appliances using the onboard relays and the five tactile buttons, with the integrated display providing a handy on-device interface for immediate control.
