LilyPad Light Sensor
-
The LilyPad Light Sensor is a sewable breakout board with an ALS-PT19 light sensor built in and ready to use right away. Each sensor outputs voltage between 0V and 3.3V depending on the level of ambient light shining on it. As more light is applied on the sensor, more current will flow from the board through the signal tab to the microcontroller you connect the sensor to. If the sensor receives no light, no current will flow through it. In a typical indoor lighting situation, the sensor will output around 1 to 2V. Adding this board into your next e-textile or wearable project will really open up the possibilities by being able to incorporate light level sensing capabilities.

SparkFun Triple Axis Accelerometer Breakout
ADXL345
-
This new version adds two standoff holes as well as an extra decoupling capacitor. The ADXL345 is a small, thin, low power, 3-axis MEMS accelerometer with high resolution (13-bit) measurement at up to +-16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.

SparkFun LiPo Fuel Gauge
-
LiPo batteries are a great way to power your projects. They're small, lightweight, and pack a pretty good punch for their size. Unfortunately, even the best batteries eventually run low on power and when they do it's often unexpected (and at the worst time). Don't be caught by surprise next time your board suddenly powers-down! The SparkFun LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect relative state of charge and direct A/D measurement of battery voltage. In other words, it tells your microcontroller how much 'fuel' is left in the tank. The LiPo Fuel Gauge communicates with your project over I2C and an alert pin also tells you when the charge has dropped below a certain percentage.

SparkFun I2C DAC Breakout
MCP4725
-
You've always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!

SparkFun Ambient Light Sensor Breakout
TEMT6000
-
Basic breakout board for the TEMT6000 Ambient Light Sensor. Only what you need, nothing you don't. Sensor acts like a transistor - the greater the incoming light, the higher the analog voltage on the signal pin.

SparkFun GPS-RTK-SMA Breakout
ZED-F9P (Qwiic)
-
Based on the SparkFun GPS-RTK2 designs, the SparkFun GPS-RTK-SMA raises the bar for high-precision GPS and is the latest in a line of powerful RTK boards featuring the ZED-F9P module from u-blox. The ZED-F9P is a top-of-the-line module for high accuracy GNSS and GPS location solutions including RTK that is capable of 10mm, three-dimensional accuracy. With this board, you will be able to know where your (or any object's) X, Y, and Z location is within roughly the width of your fingernail! The ZED-F9P is unique in that it is capable of both rover and base station operations. 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 Opto-isolator Breakout
-
This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC. This IC has two LEDs and two photodiodes built-in. This allows the low-voltage side to control a high voltage side.

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 I2S Audio Breakout
MAX98357A
-
The 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.
