DescriptionThe 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 GuideFeaturesSupply 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 OutputsNo MCLK RequiredClick and Pop ReductionShort-Circuit and Thermal Protection.

DescriptionA lot of the time you just need to add more analog inputs to solve a problem. It happens. The SparkFun Qwiic 12 Bit ADC can provide four channels of I2C controlled ADC input to your Qwiic enabled project. These channels can be used as single-ended inputs， or in pairs for differential inputs. What makes this even more powerful is that it has a programmable gain amplifier that lets you "zoom in" on a very small change in analog voltage(but will still effect your input range and resolution). Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.The ADS1015 uses its own internal voltage reference for measurements， but a ground and 3.3V reference are also available on the pin outs for users. This ADC board includes screw pin terminals on the four channels of input， allowing for solderless connection to voltage sources in your setup. It also has an address jumper that lets you choose one of four unique addresses(0x48， 0x49， 0x4A， 0x4B). With this， you can connect up to four of these on the same I2C bus and have sixteen channels of ADC. The maximum resolution of the converter is 12-bits in differential mode and 11-bits for single-ended inputs. Step sizes range from 125μV per count to 3mV per count depending on the full-scale range(FSR)setting.We have included an onboard 10K trimpot connected to channel A3. This is handy for initial setup testing and can be used as a simple variable input to your project. But don't worry， we added an isolation jumper so you can use channel A3 however you'd like.Note：The I2C address of the ADS1015 is 0x48 and is jumper selectable to 0x49， 0x4A， 0x4B. A multiplexer/Mux is required to communicate to multiple ADS1015 sensors on a single bus. If you need to use more than one ADS1015 sensor consider using the Qwiic Mux Breakout.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.Get Started with the SparkFun Qwiic 12-Bit ADC Hookup GuideFeaturesADS1015Operating Voltage(VDD)：2.0V-5.5V(Note：When powering with a Qwiic cable， the input range is only 3.3v)Operating Temperature：-40℃ to 125℃Operation Modes：Single-Shot， Continuous-Conversion(Default)， and Duty CyclingAnalog Inputs：Measurement Type：Single-Ended(Default)Input Voltage Range：GND to VDDFull Scale Range(FSR)：±.256V to ±6.114V(Default：2.048V)Resolution：12-bit(Differential)or 11-bit(Single-Ended)LSB size：0.125mV - 3mV(Default：1 mV)Sample Rate：128 Hz to 3.3 kHz(Default：1600SPS)Current Consumption(Typical)：150μA-200μAI2C Address：0x48(Default)， 0x49， 0x4A， or 0x4BScrew pin terminals for solderless connection to voltage sourcesFour unique I2C addresses：0x480x490x4A0x4B2x Qwiic connection portsOnboard 10K trimpot

DescriptionLIDAR has never looked so good! This is the LIDAR-Lite v3HP， a compact， high-performance optical distance measurement sensor from Garmin(TM). The LIDAR-Lite v3HP istheideal optical ranging solution for drone， robot， or unmanned vehicle applications. Each sensor is housed in a durable， IPX7-rated housing and includes all the core features and user configurability of the popular LIDAR-Lite v3.The v3HP is very similar in function to that of the v3 but it can now sample faster at rates greater than 1kHz(where as the v3 is only capable of up to 500Hz). Another improvement is that this v3HP model is more power efficient with current consumption rates 40mA less than the v3(that's 65mA as opposed to 105mA while idle， and 85mA instead of 130mA while acquiring).Each LIDAR-Lite v3HP has a range of 1m to 40m and features an edge-emitting， 905nm(1.3 watts)， single-stripe laser transmitter， 8m Radian beam divergence， and an optical aperture of 12.5mm. This version of the LIDAR-Lite still operates at 5VDC(6V max)with a peak power of 1.3W and still possesses an accuracy of +/- 2.5cm at >2m. On top of everything else， the LIDAR-Lite is user-configurable， allowing adjustment between accuracy， operating range and measurement time and can be interfaced via I2C or PWM with the attached 200mm cable.Note：CLASS 1 LASER PRODUCT CLASSIFIED EN/IEC 60825-1 2014.

DescriptionThe MCP9600 Breakout is a high accuracy Thermocouple Amplifier equipped with an I2C interface， accessed over our Qwiic system. Inside the chip are two temperature sensors， one for the thermocouple itself(the hot junction)and one for the chip itself(the cold junction). As a result， the MCP9600 can read both the ambient temperature and the temperature of whatever you're trying to measure! The MCP9600 can do both with a resolution of 0.0625℃， and an accuracy of ±1.5℃(worst-case). The MCP9600 Thermocouple Amplifier is one of our many Qwiic compatible boards! Simply plug and go. No soldering， no figuring out which is SDA or SCL， and no voltage regulation or translation required!This version of the board comes equipped with screw terminals to allow for your own Thermocouple's wiring to be hooked up with the turn of a screw. This makes it perfect for a variety of applications， from measuring the temperature of your Crock-Pot to making sure your backyard induction furnace is up to temperature.In addition， the MCP9600 has four on-board temperature alerts that you can configure! Instead of constantly polling the sensor over I2C， you can set a temperature limit to trigger an interrupt when the temperature reaches a certain value. This frees up your microcontroller and your I2C bus to do more important things. It's also possible to put the MCP9600 into alternate operation modes in order to save power. The sensor supports a burst mode， where it will take a specified number of samples， return the results， and then go to sleep. This low-power mode makes the MCP9600 perfect for portable applications!We've written an Arduino library to help you get started quickly. You can download the library through the Arduino library manager by searching 'SparkFun MCP9600' or you can get the GitHub repo as a .zip file and install the library from there.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.

DescriptionThe SparkFun Qwiic pHAT V2.0 for Raspberry Pi provides you with the quickest and easiest way to enter into SparkFun's Qwiic ecosystem while still using that Raspberry Pi that you've come to know and love. The Qwiic pHAT connects the I2C bus(GND， 3.3V， SDA， and SCL)on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy-chaining boards with different addresses， you can stack as many sensors as you'd like to create a tower of sensing power!The Qwiic pHAT V2.0 has four Qwiic connect ports(two on its side and two vertical)， all on the same I2C bus. We've also made sure to add a simple 5V screw terminal to power boards that may need more than 3.3V and a general-purpose button(with the option to shut down the Pi with a script). Also updated， the mounting holes found on the board are now spaced to accommodate the typical Qwiic board dimension of 1.0"×1.0". This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header as well as the NVIDIA Jetson Nano and Google Coral.NoteWhen placing a Raspberry Pi and the pHAT in an enclosure(like the Pi Tin)， we noticed that the pHAT was not fully inserted in Pi's header pins. For a secure connection， you'll need to add a pair of 1x20 stackable headers to extend the pins to your cart.The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.
