Description。The 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 Guide。Features。SparkFun Pulse Oximeter and Heart Rate Sensor。MAX30101 and MAX32664 sensor and sensor hub。Qwiic connectors for power and I2C interface。I2C Address：0x55。MAX30101 - Pulse Oximeter and Heart-Rate Sensor。Heart-Rate Monitor and Pulse Oximeter Sensor in LED Reflective Solution。Integrated Cover Glass for Optimal， Robust Performance。Ultra-Low Power Operation for Mobile Devices。Fast Data Output Capability。Robust Motion Artifact Resilience。MAX32664 - Ultra-Low Power Biometric Sensor Hub。Biometric Sensor Hub Solution。Finger-Based Algorithms Measure Pulse Heart Rate and Pulse Blood Oxygenation Saturation(SpO2)。Both Raw and processed data are available。Basic Peripheral mix optimizes size and performance

Description。The SparkFun TSH82 Configurable OpAmp Board was designed to give you the best combination of performance and flexibility that we could achieve by giving you two gain stages， each one independently accessible on the header pins. Each stage is natively configured as an inverting amplifier that can also be strung together to expand the capabilities of the TSH82 from STMicroelectronics. With the use of the jumpers on the back of the board， you can configure each stage for non-inverting operation， differential input， and DC input coupling.。Electrically speaking， both stages on this board are identical. The default configuration is inverting with a gain of -4.7 with a bandwidth of almost 10MHz. Input signals are AC coupled， possess an input impedance of 10K with a low frequency cutoff of 15.9Hz. Outputs are also DC coupled， so don't forget to add a capacitor to the output if you're running a single-ended supply and need to strip out the DC component. The board will also operate with a single-ended DC power supply of 4.5V to 12V， or a bipolar supply from +/-2.25V to +/-6V.。On the back of the board you'll find 10 solder jumpers that can be used to change the board's performance， but nothing there needs to be changed to use it in it's default state.。Get Started With the Configurable OpAmp Board Guide

Description。This is a 16mm deluxe thumb joystick and is very similar to the 'analog' joysticks found inside PlayStation controllers. Directional movements are provided simply by two potentiometers - one for each axis. These 10k potentiometers will read the position changes for the joystick's full range of physical motion. This joystick also has a select button that is actuated when the joystick is pressed down.。The mechanical parts found in this joystick are mostly metal and are considered far sturdier(rugged， if you will)than other， plastic joystick options.。Note：。This thumb joystick does not include a top cap and it will need to be purchased separately. Additionally， the leads on the housing of this joystick are much thicker than the leads on the trimpots &； push button components. When soldering to BOB-9110， we recommend using a pair of fine tip tweezers to guide each pin into the correct hole before pushing down.

Description。The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large， exposed pads function as probes for the sensor， together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be， resulting in a lower resistance and a higher SIG out. This version of the Soil Moisture Sensor includes a 3-pin screw pin terminal pre-soldered to the board for easy wiring and setup.。To get the SparkFun Soil Moisture Sensor functioning， all you will need is to connect the VCC and GND pins to your Arduino-based device(or compatible development board). You will receive a SIG out， which will depend on the amount of water in the soil. One commonly known issue with soil moisture senors is their short lifespan when exposed to a moist environment. To combat this， we've had the PCB coated in gold finishing(ENIG， or Electroless Nickel Immersion Gold).。Note：Check the Hookup Guide below for assembly and weatherproofing instructions， as well as a simple example project that you can put together yourself!。Get Started with the Soil Moisture Sensor Guide
