DescriptionThis 2x13 shrouded header has the same number and spacing of pins as the Raspberry Pi so you can easily connect via ribbon cable to the low-level peripherals and get hacking! This through-hole header has 26 0.1"-spaced pins and is keyed for

DescriptionThe SCD30 from Sensirion is a high quality Nondispersive Infrared(NDIR)based CO2 sensor capable of detecting 400 to 10000ppm with an accuracy of ±(30ppm+3%). In order to improve accuracy the SCD30 has temperature and humidity sensing built-in， as well as commands to set the current altitude. For additional accuracy the SCD30 also accepts ambient pressure readings!We've written an Arduino library to make reading the CO2， humidity， and temperature very easy. It can be downloaded through the Arduino Library manager：search for 'SparkFun SCD30' or it can be found in theDocumentstab above.The SCD30 Humidity and Temperature Sensor can also be automatically detected， scanned， configured， and logged using the OpenLog Artemis datalogger system. No programming， soldering， or setup required!Note：The SCD30 has an automatic self-calibration routine. Sensirion recommends 7 days of continuous readings with at least 1 hour a day of 'fresh air' for self-calibration to complete.FeaturesPower supply voltage：3.3V - 5.5VNDIR CO2 sensor technologyIntegrated temperature and humidity sensorBest performance-to-price ratioDual-channel detection for superior stabilitySmall form factor：35 mm×23 mm×7 mmMeasurement range：400 ppm - 10.000 ppmAccuracy：±(30 ppm + 3%)Current consumption：19 mA @ 1 meas. per 2 s.Energy consumption：120 mJ @ 1 measurementFully calibrated and linearizedDigital interface UART or I2C

DescriptionThe LilyPad Sewable Electronics Kit lets you explore the wonderful world of electronic sewing(e-sewing)and e-textiles through a series of introductory projects using the LilyPad system. You'll learn how to sew basic circuits to light up LEDs， control them with buttons and switches and even experiment with a pre-programmed LilyMini circuit that reacts to ambient light levels. In addition to LilyPad LEDs and battery holders， the kit comes with two LilyPad ProtoSnap boards that let you explore the circuit before you sew the pieces into a project.The full-color LilyPad Sewable Electronics Kit Guide(included)contains step-by-step instructions for using LilyPad pieces to create four complete sewable circuit projects with conductive thread. Easy-to-follow diagrams and troubleshooting tips make this a great introductory resource for crafters and creatives.LilyPad is a wearable technology developed by Dr. Leah Buechley and cooperatively designed by Dr. Buechley and SparkFun. Each LilyPad component was creatively constructed with large sew tabs to allow for stitching into clothing. Various input， output， power and sensor boards are available. They're even washable!Note：A portion of this sale is given back to Dr. Buechley for continued development and education in e-textiles.Note：Due to the requirements of shipping the batteries in this kit， orders may take longer to process and therefore do not qualify for same-day shipping. Additionally， these batteries can not be shipped via Ground or Economy methods to Alaska or Hawaii.

DescriptionThe LilyMini ProtoSnap is a great way to get started learning about creating interactive e-textile circuits before you start sewing. Like other LilyPad ProtoSnap boards， the LilyMini ProtoSnap has all of its pieces wired together out of the box， enabling you to test the circuit's function before you sew. At the center of the board is a pre-programmed LilyMini microcontroller connected to a LilyPad Light Sensor， LilyPad Button and two pairs of LilyPad LEDs.The LilyMini ProtoSnap ships with pre-loaded code that uses all the LilyPad pieces connected to it. This sample code has three modes， which can be selected by pressing the LilyPad Button on the bottom-left side of the ProtoSnap. The built-in RGB LED on the LilyMini will change color to indicate which mode has been selected：White：All LEDs on.Magenta：LEDs fade in and out in a breathing pattern. When the light sensor is covered， LEDs fade faster.Cyan：LEDs off. When the light sensor is covered， LEDs will twinkle.The LilyMini board， at the center of the ProtoSnap， has a built-in battery holder for a CR2032 battery(included). On the opposite side of the LilyMini you will find the SAMD11 brain， which controls the ProtoSnap.Note：A portion of this sale is given back to Dr. Leah Buechley for continued development and education in e-textiles.Note：The LilyPad LilyMini ProtoSnap does NOT include sewing needles or conductive thread. These items will need to purchased separately.Warning：You cannot reprogram this product and any attempt at programming is at your own risk!Get Started with the LilyMini ProtoSnap Guide

DescriptionThe SparkFun 2D Barcode Scanner Breakout is a nifty little breakout board featuring the DE2120 barcode scanner module from DYScan. The DE2120 reads 20 different barcode symbologies(both 1D and 2D)using a camera coupled with on-board image processing to identify and decode everything from UPC codes to QR codes. The module also features two LEDs：one for illumination and one to project the red line that you're used to seeing from laser-based scanners.This breakout board makes it easy to explore all of the capabilities of the DE2120 without dealing with finicky flat flex cables. The scanner's USB interface is exposed via the on-board USB-C connector. A buzzer and status LED are connected to the module through appropriate drive circuits and a push button tactile switch is provided on the "trigger" pin. When you're ready to incorporate the module into your embedded project， you can leverage the 5 pin header for direct access to the TTL serial pins， power pins， and trigger input.The module can be configured either by using the serial interface or by scanning command barcodes found in the Settings Manual.All keyboard， HID， and serial can be transmitted over the single USB-C connector. The DE2120 has the unique ability to enumerate all three protocols including a CDC serial driver so the device appears as a standard COM port.Get Started with the 2D Barcode Scanner Breakout Hookup GuideFeaturesUSB-C Connector for USB HID Interface and Virtual COM portReads 20 different symbologies1D SymbologiesUPC-AUPC-EEAN-8EAN-13Code 128GS1-128Code 39Code 93Code 11Interleaved 2-of-5Matrix 2-of-5Industrial 2-of-5CodabarMSIGS1 DataBarDatalogic 2-of-52D SymbologiesQR CodeData MatrixPDF 417Micro PDF 417Aztec Code
