DescriptionThe great thing about open source is that while SparkFun has designed our own MicroMod carrier boards， that does not stop you from creating your very own MicroMod carrier board. The MicroMod DIY Carrier Kit includes five M.2 connectors(4.2mm height)， screws， and standoffs so that you can get all the special parts you may need to make your own carrier board.MicroMod uses the common M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic 'key' on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the 'E' key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The 'E' key is fairly common so a user could insert a M.2 compatible Wifi module but because the screw mount doesn't align， the user would not be able to secure an incompatible device into a MicroMod carrier board.MicroMod is a modular interface ecosystem that connects a microcontroller "processor board" to various "carrier board" peripherals. Utilizing the M.2 standard， the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

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.

DescriptionArduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer(e.g. Flash， Processing， MaxMSP). The open-source IDE can be downloaded for free(currently for Mac OS X， Windows， and Linux).The Arduino Mega is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins(of which 14 can be used as PWM outputs)， 16 analog inputs， 4 UARTs(hardware serial ports)， a 16 MHz crystal oscillator， a USB connection， a power jack， an ICSP header， and a reset button.

DescriptionThe SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C based biometric sensor， utilizing two chips from Maxim Integrated：the MAX32664 Biometric Sensor Hub and the MAX30101 Pulse Oximetry and Heart Rate Module. While the latter does all the sensing， the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations， digital filtering， pressure/position compensation， advanced R-wave detection， and automatic gain control. We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small， measuring at 1in×0.5in(25.4mm×12.7mm)， which means it will fit nicely on your finger without all the bulk.The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664 which applies its algorithms to determine heart rate and blood oxygen saturation(SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting as well as a handy finger detection data point. To get the most out of the sensor we've written an Arduino Library to make it easy to adjust all the possible configurations.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 Pulse Oximeter and Heart Rate Monitor Hookup GuideFeaturesSparkFun Pulse Oximeter and Heart Rate SensorMAX30101 and MAX32664 sensor and sensor hubQwiic connectors for power and I2C interfaceI2C Address：0x55MAX30101 - Pulse Oximeter and Heart-Rate SensorHeart-Rate Monitor and Pulse Oximeter Sensor in LED Reflective SolutionIntegrated Cover Glass for Optimal， Robust PerformanceUltra-Low Power Operation for Mobile DevicesFast Data Output CapabilityRobust Motion Artifact ResilienceMAX32664 - Ultra-Low Power Biometric Sensor HubBiometric Sensor Hub SolutionFinger-Based Algorithms Measure Pulse Heart Rate and Pulse Blood Oxygenation Saturation(SpO2)Both Raw and processed data are availableBasic Peripheral mix optimizes size and performance
