Description。The SparkFun I2S Audio Breakout board uses the MAX98357A digital to analog converter(DAC)， which converts I2S(not be confused with I2C)audio to an analog signal to drive speakers. The I2S Audio Breakout converts the digital audio signals using the I2S standard to an analog signal and amplifies the signal using a class D amplifier which can deliver up to 3.2W of power into a 4Ω load. The board can be configured to output only the left channel audio， right channel， or both.。The SparkFun I2S Audio Breakout board is fairly simple， requiring only a few pin connections to get it up and working. By default the board is configured in "mono" operation， meaning the left and right signals are combined together to drive a single speaker. If you want a separate speaker for the left and right audio channels you'll need to cut the mono jumper. In addition to being able to select the audio channel output， the gain can also be configured in a few ways. The gain of the amplifier can be configured from as low as +3dB to as high as +15dB. While the channel selection can be configured on board， the gain however is controlled externally using the gain pin. By default， the board is configured for +9dB， but can be easily changed!。Get Started with the SparkFun I2S Audio Breakout Guide。Features。Supply Voltage Range：2.5V - 5.5V.。Output Power：3.2W into 4Ω at 5V.。Output Channel Selection：Left， Right， or Left/2 + Right/2(Default).。Sample Rate：8kHz - 96kHz.。Sample Resolution：16/32 bit.。Quiescent Current：2.4mA.。Filterless Class D Outputs。No MCLK Required。Click and Pop Reduction。Short-Circuit and Thermal Protection.

Description。The LilyPad ProtoSnap Plus is a sewable electronics prototyping board that you can use to explore circuits and programming， then break apart to make an interactive fabric or wearable project. Programming the ProtoSnap Plus is easy with the free Arduino software you'll need to program the ATmega32U4 on LilyPad USB Plus at the heart of the board. Once you've installed the software， you'll be able to write and upload your own programs to the board， making it do almost anything you want.。At the center of the ProtoSnap Plus is the LilyPad USB Plus microcontroller， pre-wired to a LilyPad board including a LilyPad Light Sensor， LilyPad Buzzer， LilyPad Button Board， four pairs of colored LilyPad LEDs and a LilyPad Slide Switch. Because these components are connected together on the ProtoSnap board， you can test out your project ideas before you sew. The ProtoSnap Plus also includes expansion ports that let you sew your wearables together or use alligator cables to easily connect external sensors and components. After testing out your coding ideas using the attached LilyPad pieces， you can break apart the prototyping board and sew them into your project!。Please be aware that the Lilypad ProtoSnap Plus is。NOT supported on Windows 7/8。due to a lack of support drivers for those specific OS's.。Note：。A portion of this sale is given back to Dr. Leah Buechley for continued development and education in e-textiles.。Get Started with the LilyPad ProtoSnap Plus Guide

。Description。The 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 Guide。Features。USB-C Connector for USB HID Interface and Virtual COM port。Reads 20 different symbologies。1D Symbologies。UPC-A。UPC-E。EAN-8。EAN-13。Code 128。GS1-128。Code 39。Code 93。Code 11。Interleaved 2-of-5。Matrix 2-of-5。Industrial 2-of-5。Codabar。MSI。GS1 DataBar。Datalogic 2-of-5。2D Symbologies。QR Code。Data Matrix。PDF 417。Micro PDF 417。Aztec Code
