DescriptionThe SparkFun ProtoShield Kit lets you customize your own Arduino shield using whatever circuit you can come up with and then test it to make sure everything is working the way it should! The SparkFun ProtoShield Kit is based off the Arduino R3's footprint that allows you to easily incorporate it with favorite Arduino-based device.One of our favorite features with this version of the ProtoShield Kit is the solderable-like breadboard prototyping area! Half of this area was designed with a breadboard in mind. On the underside of the shield you will be able to see open jumper pads between each through hole to make a connection like a breadboard. Once you add a component， simply add a solder jumper between holes to make a connection. For those that prefer the standard prototyping pads， we left the other side(near the BlueSMiRF and Serial UART ports)as is.We have also moved the prototype testing components(those used to make sure your circuit works effectively)off of the "mainland" of the shield and onto a ProtoSnap styled， removable PCB. On this test area you will find soldering areas for the two yellow 3mm LEDs(as well as pins to control and power them)， two 330 Ohm resistors， a 10K Ohm resistor， and a pushbutton.Note：Since this product is a kit， assembly and a basic knowledge of soldering will be required. The SparkFun ProtoShield Kit does not come pre-assembled.Get Started With the SparkFun ProtoShield Kit GuideFeaturesArduino R3 FootprintSoldering KitSolderable-Like BreadboardBlueSMiRF or Comparable 6-pin PinsDetachable Test Area

DescriptionThe CD40106BE consists of six Schmitt-trigger circuits. Each circuit functions as an inverter with Schmitt-trigger action on the input. The trigger switches at different points for positive- and negative-going signals. The difference between the positive-going voltage(VP)and the negative-going voltage(VN)is defined as hysteresis voltage(VH).FeaturesSchmitt trigger action with no external componentsHysteresis voltage typ. at 0.9V at VDD = 5V， 2.3V at VDD = 10V， and 3.5V at VDD = 15VNoise immunity greater than 50%No limit on input rise and fall timesStandardised， symmetrical output characteristics100% tested for quiescent current at 20sVMaximum input current of 1μA at 18 V over full package temperature range； 100nA at 18V and 25℃Low VDD to VSS current during slow input ramp

DescriptionThe HM01B0 from Himax Imaging is an ultra low power CMOS Monochrome Image Sensor that enables the integration of an "Always On" camera for computer vision applications such as gestures， intelligent ambient light and proximity sensing， tracking and object identification. The sensor allows the sensor to consume very low power of <2mW at QVGA 30FPS. This low power consumption and vision applications camera comes with a ribbon cable that mates to the camera connector populated on the following products：MicroMod Machine Learning Carrier BoardArtemis Development KitEdge Development Board - Apollo3 BlueThe HM01B0 contains 320×320 pixel resolution and supports a 320×240 window mode which can be readout at a maximum frame rate of 60FPS， and a 2×2 monochrome binning mode with a maximum frame rate of 120FPS. The video data is transferred over a configurable 1bit， 4bit or 8bit interface with support for frame and line synchronization. The sensor integrates black level calibration circuit， automatic exposure and gain control loop， self-oscillator and motion detection circuit with interrupt output to reduce host computation and commands to the sensor to optimize the system power consumption.FeaturesImage SensorUltra Low Power Image Sensor(ULPIS)designed for Always On vision devices and applicationsHigh sensitivity 3.6μ BrightSenseTM pixel technology320×320 active pixel resolution with support for QVGA window， vertical flip and horizontal mirror readoutProgrammable black level calibration target， frame size， frame rate， exposure， analog gain(up to 8x)and digital gain(up to 4x)Automatic exposure and gain control loop with support for 50 / 60Hz flicker avoidanceFlexible 1bit， 4bit and 8bit video data interface with video frame and line syncMotion Detection circuit with programmable ROI and detection threshold with digital output to serve as an interruptOn-chip self oscillatorI2C 2-wire serial interface for register accessHigh CRA for low profile module designSensor ParametersActive Pixel Array 320×320Pixel Size 3.6 μm×3.6 μmFull Image Area 1152 μm×1152 μmDiagonal(Optical Format)1.63 mm(1/11″)Scan Mode：ProgressiveShutter Type：Electronic Rolling ShutterFrame Rate MAX 51 fps @ 320×320， 60 fps @ 320×240(QVGA)CRA(maximum)30℃Sensor SpecificationsSupply Voltage：Analog - 2.8 V， Digital - 1.5V(Internal LDO：1.5V - 2.8V)， I/O - 1.5 - 2.8VInput Reference Clock：3 - 50 MHzSerial Interface(I2C)：2-wire， 400 KHz max.Video Data Interface：1b， 4b， 8b with frame / line SYNCOutput Clock Rate MAX：50 MHz for 1bit， 12.5 MHz for 4bit， 6.25 MHz for 8bitEst.

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
