SparkFun Pulse Oximeter And Heart Rate Sensor
MAX30101 & MAX32664 (Qwiic)
-
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 x 0.5in (25.4mm x 12.7mm), which means it will fit nicely on your finger without all the bulk.

SparkFun LED Driver Breakout
LP55231
-
The SparkFun LP55231 LED Driver Breakout is a self-contained solution for developing and deploying the nine-channel I2C LED controller. Remarkably simple, the breakout is equipped primarily with just the LP55231 LED controller IC, plus three RGB LEDs. It also features pads and jumpers for replacing the onboard LEDs with external ones, and configuring the I2C bus, which allows you to daisy-chain up to four LP55231s. This breakout drives the LEDs using Pulse Width Modulation (PWM), so it is well-suited for variable intensity and color-mixing applications!

SparkFun GPS Breakout
ZOE-M8Q (Qwiic)
-
The SparkFun ZOE-M8Q GPS Breakout is a high accuracy, miniaturized, GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. 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.

SparkFun ToF Range Finder Breakout for VL6180
12784
-
This is the SparkFun "Time-of-Flight" Range Finder, a breakout for the VL6180 distance sensor. Unlike most distance sensors that rely reflected light intensity or reflected angles to determine range, the VL6180 uses a precise clock to measure the time it takes light to bounce back from a surface. This affords the ToF Range Finder and VL6180 a great benefit over other methods because it can be much more accurate and more immune to noise. Does this technology sound familiar? Well it should, it's the same means cellphones use to detect when the caller is holding their phone to their ear.

SparkFun 16 Output I/O Expander Breakout
SX1509
-
Are you low on I/O? No problem! The SX1509 Breakout is a 16-channel GPIO expander with an I2C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin control. It can produce PWM signals, so you can dim LEDs. It can be set to blink or even breathe pins at varying rates. This breakout is similar to a multiplexer or "mux," in that it allows you to get more IO from less pins. And, with a built-in keypad engine, it can interface with up to 64 buttons set up in an 8x8 matrix.

SparkFun Triple Axis Digital Accelerometer Breakout
ADXL313 (Qwiic)
-
The SparkFun ADXL313 Breakout is a low power, high resolution (up to 13-bits) 3-axis accelerometer for measurement up to ±4g. This breakout measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Digital output data is formatted as 16-bit two's complement and is accessible through the on-board Qwiic connectors (I2C) or SPI.

Qwiic Pressure/Humidity/Temp (PHT) Sensor - MS8607
-
The MS8607 from TE is an impressive combination pressure, humidity, temperature (PHT) sensor with accuracy of ±2mbar pressure, ±3% humidity, and ±1°C. Perfect for sensing general weather conditions the MS8607 really shines for high altitude, low pressure applications. Capable of sensing down to 10mbar, this pressure sensor separates itself from many other I2C pressure sensors like the BME280. The MS8607 is simple to use and gives the user some very powerful readings with very little power and conversion time.

SparkFun Altitude/Pressure Sensor Breakout
MPL3115A2
-
Life has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled). The sensor outputs are digitized by a high resolution 24-bit ADC and transmitted over I2C, meaning it's easy to interface with most controllers. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in fractions of a meter. The device also provides 12-bit temperature measurements in degrees Celsius.
