    Precio:  $3,973.00

    Adafruit (PID 3244) Mini 3-Layer Round Robot Chassis Kit -..

    -Titulo Original : Adafruit (PID 3244) Mini 3-Layer Round Robot Chassis Kit - 2WD with DC Motors-Fabricante : ADAFRUIT-Descripcion Original: Mini 3-Layer Round Robot Chassis Kit - 2WD with DC Motors // Includes Chassis, 2 motors, 2 wheels and the plastic caster ball // Does not include motor drivers, battery, micro controller board. // Motor driven by 3-6VDC, 200-400mA run, 1.5A hard stall // Nice mini robot chassis kit // This kit gives you everything you need to build the shell of a 2-wheel-drive Mobile Platform Robot! You get the metal plates that make up the chassis, two DC drive motors with matching wheels, and a caster ball for balance. You'll fill in the rest with a power supply, microcontroller board, and motor controller. The differential drive (two separately driven wheels) allows for a near zero turning radius while the high-strength aluminum alloy body plus high-quality high-speed motors make it suitable for flat indoor surfaces. It's adorably small like our other round robot, but has an extra layer for more storage and comes in fashionable Adafruit black! We of course have suggestions to run the motors like our TB6612 breakout, Motor FeatherWing, Motor Shield for Arduino, or Motor HAT for Raspberry Pi. Basically anything that can do two bi-directional brushed DC motors at ~5V and 1.5 Amp peak. To steer the wheels, you'll need a microcontroller to toggle the motor driver like our Feather 32u4 Bluefruit LE, which we used for AdaBox002, and to power the robot we used a 4 x AA battery holder (not included) which fits nicely between layer #2 and #3. But this is all up to you and your imagination! Note: LiPoly Battery, Feather board, FeatherWings, and Feather accessories are not included! This is just the body of the mobile platform robot. Purchasing AdaBox002 will set you up with nearly everything you need, or you can use whatever microcontroller and motor drivers you already have. Kit includes: 2x Drive Motors (drive with 3-6VDC, 200-400 mA run, 1.5A hard stall) 2x Wheels 1x Plastic Caster Ball Anodized aluminum frames and all mounting hardware for assembly Assembled Dimensions: Length of Metal Plates: 100mm / 3.9 Width of Car (wheels assembled): 109mm / 4.3 Height (wheels assembled, 3 plates): 66mm / 2....

    Precio:  $1,756.00

    Adafruit I2C Non-Volatile FRAM Breakout - 256Kbit / 32KByte

    -Titulo Original : Adafruit I2C Non-Volatile FRAM Breakout - 256Kbit / 32KByte [ADA1895]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1895 // Stock Type: Breakout Boards >> Storage // In Stock & Ready to Ship // FRAM, or Ferroelectric Ram, is the coolest new data storage method that all the fashion magazines are talking about. Oh wait, no that's quilted handbags. But FRAM is pretty damn cool too! It's similar to Dynamic random-access memory, only with a ferroelectric layer instead of a dielectric layer. This gives it stable handling (the bytes you write are non-volatile) with dynamic responsiveness (you can write them very fast!) Now, with our I2C FRAM breakout board you can add some FRAM storage to your next DIY project. FRAM allows for a lower power usage and a faster write performance. It's excellent for low-power or inconsistent-power datalogging or data buffering where you want to stream data fast while also keeping the data when there's no power. Unlike Flash or EEPROM there's no pages to worry about. Each byte can be read/written 10,000,000,000,000 times so you don't have to worry too much about wear leveling. This particular FRAM chip has 256 Kbits (32 KBytes) of storage, interfaces using I2C, and can run at up to 1MHz I2C rates. Each byte can be read and written instantaneously (like SRAM) but will keep the memory for 95 years at room temperature. We picked up the largest chip that has I2C and is also 5V compliant. You can use this chip with either 3V or 5V power and logic. It comes in a breadboard-friendly breakout and a spare stick of 0.1 male header for soldering on. We also have an SPI FRAM breakout board - which is smaller in size but faster (20MHz max SPI clock rate...

    Adafruit Accessories Adafruit Perma-Proto HAT for Pi Mini...

    -Titulo Original : Adafruit Accessories Adafruit Perma-Proto HAT for Pi Mini Kit - No EEPROM (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2310 // Stock Type: Raspberry Pi >> Pi HATs & Plates >> Hats // In Stock & Ready to Ship // Design your own Pi HAT, attach custom circuitry and otherwise dress your Pi A+, B+, or Pi 2 with this jaunty prototyping HAT kit.To kick off the Adafruit HAT party, we have this Perma-Proto inspired plug in daughter board. It has a grid of 0.1 prototyping soldering holes for attaching chips, resistors, LED, potentiometers and more. The holes are connected underneath with traces to mimic the solderless breadboards with which you're familiar. There's also long power strips for +3V, +5V and Ground connections to the Pi. Near the top we break out nearly every pin you could want to connect to the Pi (#26 didn't quite make the cut).This is just the basic version of our Perma-Proto HAT.  It comes with a printed circuit board and a single 2x20 GPIO Header for Raspberry Pi  to put your Perma-Proto on top of your Raspberry Pi (like a nice little hat...) This version does not come with an EEPROM so you can 'stack' it with other HATs without worrying about an EEPROM address collision.You can customize your Perma-Proto setup using a standard 2x20 stacking header or extra tall 2x20 stacking header . You can also swap out the 2x20 header with a slim 2x20 type if you want it to sit closer to the Pi , or an extra tall one if you want it to sit above the USB/Ethernet ports .A bit of light soldering is required to attach the header to the PCB but it's easy work. This hat is only compatible with the Raspberry Pi A+, B+ or Pi 2!  It will not work with the Raspberry Pi Model A or B. Our initial version has the +3V and +5V markings in blue, and the GND markings in red, future orders will have these colors swapped to better match a solderless breadboar...

    -Titulo Original : Adafruit FadeCandy - Dithering USB-Controlled Driver for RGB NeoPixels [ADA1689]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1689 // Stock Type: NeoPixels >> Drivers // In Stock & Ready to Ship // A new collaboration between Adafruit & Micah from Scanlime , we are excited to introduce Fadecandy, a NeoPixel driver with built in dithering, that can be controlled over USB. Fadecandy is not just hardware! It is a kit of both hardware and software parts that make LED art projects easier to build and better-looking so sculptors and makers and multimedia artists can concentrate on beautiful things instead of reinventing the wheel. It's an easy way to get started and an advanced tool for professionals. It's a collection of simple parts that work well together: Firmware that uses unique dithering and color correction algorithms to raise the bar for quality while getting out of the way of your creativity. Open source hardware for connecting cheap and popular WS2811 based LEDs to a laptop, desktop, or Raspberry Pi over USB. Fadecandy Server Software , which communicates with one Fadecandy board or dozens. It runs on Windows, Linux, and Mac OS, and on embedded platforms like Raspberry Pi. The Open Pixel Control protocol, a simple way of getting pixel data from your creative tools into the Fadecandy server. Libraries and examples for popular languages. We have Python and Processing already, with Javascript and Max coming soon. LEDs! Fadecandy works with Adafruit's popular WS2811/WS2812 LEDs. Each controller board supports up to 512 LEDs, arranged as 8 strips of 64 each. Not for use with RGBW NeoPixels, you can only use RGB type at this time.Headers are not included but we have tons of different kinds of dual header in the shop if you want to solder something into the pads. Fadecandy is designed to enable art that is subtle, interactive, and playful - exploring the interplay between light, form, and shadow.
