  • Display Development Tools TFP401 HDMI/DVI Breakout w/touch
    Precio:  $10,159.00

    Display Development Tools TFP401 HDMI/DVI Breakout w/touch

    -Titulo Original : Display Development Tools TFP401 HDMI/DVI Breakout w/touch-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2219 // Stock Type: LCDs & Displays >> HDMI/DVI Decoders // In Stock & Ready to Ship // It's a mini HDMI decoder board! So small and simple, you can use this board as an all-in-one display driver for TTL displays, or perhaps decoding HDMI/DVI video for some other project. This breakout features the TFP401 for decoding video, and for the touch version, an AR1100 USB resistive touch screen driver.The TFP401 is a beefy DVI/HDMI decoder from TI. It can take unencrypted video and pipe out the raw 24-bit color pixel data - HDCP not supported! It will decode any resolution from 25-165MHz pixel clock, basically up to 1080p. We've used this breakout with 800x480 displays, so we have not specifically tested it with higher resolutions. We added a bunch of supporting circuitry like a backlight driver and configured it for running basic TTL display panels such as the ones we have in the shopYou can even power the display and decoder from a USB port. For example, with a 5 800x480 display and 50mA backlight current, the current draw is 500mA total. You can reduce that down  370mA by running the backlight at half-brightness (25mA). With the backlight off, the decoder and display itself draws 250mA. If you want more backlight control, there's a PWM input, connect that to your microcontroller or other PWM output and you can continuously dim the backlight as desiredWe have two versions, one is video only and one is video+touch. This is the version with touch! Pair it with a screen that has a resistive touch overlay. The USB port then acts as both power and data, with the touch screen appearing like a USB mouse. We've tested it sucessfully on Mac, Windows, and Debian Linux (Raspbian on a Raspberry Pi). Other Linux distributions may or may not work, but if you're running Linux you're probably used to that.This driver is designed specifically as a small and easy to use display driver for our 40-pin TTL displays. In particular, we suggest it for use with single board computers (or desktop/laptops!) w...

    Precio:  $3,239.00

    Adafruit I2S MEMS Microphone Breakout - SPH0645LM4H (3421)

    -Titulo Original : Adafruit I2S MEMS Microphone Breakout - SPH0645LM4H (3421)-Fabricante : ADAFRUIT-Descripcion Original: small, low cost MEMS mic with a range of about 50Hz - 15KHz // there are three digital pins: // The microphone is a single mono element // This I2S MEMS microphone is bottom ported // MEMS mics can detect sound and convert it to voltage // Listen to this good news - we now have a breakout board for a super tiny I2S MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they're way smaller and thinner. This microphone doesn't even have analog out, its purely digital. The I2S is a small, low cost MEMS mic with a range of about 50Hz - 15KHz, good for just about all general audio recording/detection. The microphone is a single mono element. You can select whether you want it to be on the Left or Right channel by connecting the Select pin to power or ground. If you need stereo, pick up two microphones! You can set them up to be stereo by sharing the Clock, WS and Data lines but having one with Select to ground, and one with Select to high voltage. This I2S MEMS microphone is bottom ported, so make sure you have the hole in the bottom facing out towards the sounds you want to read. It's a 1.6-3.6V max device only, so not for use with 5V logic (its really unlikely you'd have a 5V-logic device with I2S anyways). Many beginner microcontroller boards don't have I2S, so make sure its a supported interface before you try to wire it up! This microphone is best used with Cortex M-series chips like the Arduino Zero, Feather M0, or single-board computers like the Raspberry P...

    Adafruit PID 2030 PowerBoost 1000 Basic 5V USB Boost 1000ma

    -Titulo Original : Adafruit (PID 2030 PowerBoost 1000 Basic - 5V USB Boost @ 1000mA from 1.8V+-Fabricante : ADAFRUIT-Descripcion Original: Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output // 4A internal switch means you can get 1000mA+ from as low as 1.8V, 1500mA+ from 2 NiMH or Alkaline batteries, and at least 2000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines. Just make sure your batteries can actually supply the required 2-4A, OK? // Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for the most common usage of LiPo/LiIon battery usage // On-board 1000mA charge-rate 'Apple/iOS' data resistors. Solder in the included USB connector and you can plug in any iPhone or iPod for a speedy 1000mA charge rate. Works with iPads, both mini and 'classic' type. // Full breakout for battery in, control pins and power out 90%+ operating efficiency in most cases (see datasheet for efficiency graphs), and low quiescent current: 5mA when enabled and power LED is on, 20uA when disabled (power and low batt LED are off) // PowerBoost is the perfect power supply for your power-hungry portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects. With a beefy 4A DC/DC converter, it can give you 1A+ from as low as 2V. Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. The PowerBoost 1000 has at the heart a TPS61030 boost converter from TI. This boost converter chip has some really nice extras such as low battery detection, 4A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation. Check out these specs! Great for powering your robot, Arduino project, single-board-computer such as Raspberry Pi or BeagleBone! Each order comes with one fully assembled and tested PCB, a loose 2-PH JST jack, a 2-pin Terminal block and a loose USB A jack. If you are powering your project from USB, solder the USB A jack in (a 3-minute soldering task). Then choose either JST for input (JST is often used for our LiIon batteries, but the connector is only rated for 2A) or a terminal block. The 1000 version comes with a 2-pin terminal block so you can solder it to the output spot where the USB jack would go. Or don't solder any connectors in for a more compact power pack and go with 22AWG wires soldered directly in...
