DescriptionThis is a 50mm long 4-conductor cable with 1mm JST termination. It's designed to connect Qwiic enabled components together but can be used for other applications as well. The cable insulation is made from a highly malleable material making it more flexible than our original Qwiic cable particularly in tight spaces or enclosures.Each Qwiic Cable's wires have been color coded to red， black， blue and yellow.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.FeaturesDimensions：50mm(1.96")Length

DescriptionThis sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit(configurable)temperature readings over a 1-Wire interface， so that only one wire(and ground)needs to be connected from a central microprocessor. Power for reading， writing， and performing temperature conversions can be derived from the data line itself with no need for an external power source.Because each DS18B20 contains a unique silicon serial number， multiple DS18B20s can exist on the same 1-Wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls， sensing temperatures inside buildings， equipment or machinery， and process monitoring and control.Note：The pinout for this sensor is as follows：RED=Vcc BLACK=GND WHITE=SIGFeatures3.0-5.5V input voltage-55℃ to +125℃ temperature range±0.5℃ accuracy from -10℃ to +85℃Waterproof1 Wire interfaceProbe is 7mm in diameter and roughly 26mm long. Overall length(including wire)is 6 feet.Thermometer resolution is programmable from 9 to 12 bits.Electrical performance：no flicker or breakdown within AC 1200V/1S ，within DC 500V theinsulation resistance shall be greater than 100MΩ

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 LIDAR-Lite v4 LED sensor is the next step in the LIDAR-Lite line. A small， lightweight， low-power optical ranging sensor. It's the first to incorporate ANT profile wireless networking technology into an optical sensor. Its built-in nRF52840 processor means that developers can create custom applications， or be operated as a stand-alone device right out of the box by using the preloaded stock application.Like the LIDAR-Lite v3 and LIDAR-Lite v3HP sensors； it can also be directly connected to an external micro-controller running a custom user application. As such， it provides a highly adaptable option for OEM and maker applications in robotics， Internet of Things， and unmanned vehicles ― or any application where an ultrasonic sensor might otherwise be used. It's perfect as the basic building block for applications where wireless capabilities， small size， light weight， low power consumption and high performance are important factors in a short-range， 10-meter， optical distance measuring sensor.The LIDAR-Lite v4 requires an external 5VDC power source and soldering is required. This Time-of-Flight ranging module uses a LED and optics for ranging. It does not use a laser； therefore， it is inherently eye-safe under normal usage.FeaturesResolution：1 cmMeasurement repeatability：As measured indoors to a 90% reflective target1 cm is equivalent to 1 standard deviationUsing "high accuracy" mode， with averaging：+/- 1 cm to 2 meters+/- 2 cm to 4 meters+/- 5 cm to 10 metersRange：5 cm to 10 meters(as measured from back of unit)Update rate：I2C = >200 Hz typicalANT(R)= up to 200 Hz to a 90% target indoors at 2m in normal operating modeInterface：I2C or ANT； user configurable for SPI using the Nordic SDKPower(operating voltage)：4.75 - 5.25 VDCCurrent consumption：2mA idle， 85mA during acquisitionOperating temperature：-20 to 60° CLED wavelength：940 nmBeam divergence：4.77°Optical aperture：14.9 mmUnit size(HxWxD)：2.1"×0.8"×0.9"(52.2×21.2×24.0 mm)Weight：14.6 g(0.5 oz)

DescriptionPassive Infrared(PIR)sensors are great for detecting motion in a small area around the sensor. The 170μA SparkFun EKMC4607112K PIR Breakout is a simple board equipped with an EKM-series PIR sensor from Panasonic(R). The EKM-series PIR sensors are optimized for small movements to offer motion-sensing options for continuously powered applications.PIR sensors do not return specific distance data but instead monitor for IR light coming from objects in their field of view and will activate their signal when motion is detected in their sensing area， making them perfect for applications such as turning devices on automatically when motion is detected. Applications include home and building automation for energy saving， automated on/off lighting control， security， appliances， and IoT.Panasonic's low-profile PIR motion sensors(10.9mm versus standard 14.4mm height offer space savings for constrained designs)consist of a lens to create various detection zones， an optical filter to block non-infrared light， pyroelectric sensing elements， electromagnetic shielding to all circuitry， and an impedance converter to get an electrical signal. This PIR sensor offers digital output across 32 zones at 5m detection distance with 90°×90° detection area.Note：The sensitivity of passive infrared sensors is influenced by environmental conditions， so a performance evaluation test under representative conditions is recommended.Get Started with the SparkFun PIR Breakout GuideFeaturesOperating Voltage：2.3-4.0V170 μAstandby current consumptionLens diameter - 10.4mmLens Height - 10.9mm5m detection distance90°×90°(±45°)detection area

This is a must-have tool for any hobbyist's workbench.Each of these flux pens can be used in leaded and lead-free applications and is VOC， halide and rosin free --- making it RoHS II and REACH compliant. Since this is a "no-clean" style flux， you won't have to worry about any sort of conductivity issues associated with it interfering with your board or project. However， it is advisable to still clean whatever you are using this flux pen on with basic isopropyl alcohol(IPA)， because a clean board is a happy board!Note：It isn't recommended to use this flux with solder that has a water-soluble or rosin flux core in scenarios that require your boards operate at a high reliability rate. At a hobbyist level you should have no issues.FeaturesFlux Type：No-Clean Liquid Flux(for leaded and lead-free applications)Flux Classification：INM0Packaging：10mL PenShelf Life：Refrigerated >24 months； Unrefrigerated >24 months
