Accelerometor, Gyro, Magnetometer Breakout Board
SEN-38001
-
The LSM9DS1 is a highly configurable, flexible and precise motion sensing solution from ST Microelectronics - the latest in a wide-ranging inertial product line. It integrates a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer into a single IC , giving you a full nine degrees of freedom (9-DOF) in a tiny 3mm x 3.5mm package. Even with support components, square mounting pattern and connection breakouts for both SPI and I2C, this board is barely the size of a quarter.

SparkFun GPS Breakout
NEO-M9N, U.FL (Qwiic)
-
The SparkFun NEO-M9N GPS Breakout is a high quality GPS board with equally impressive configuration options. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~1.5 meter accuracy. This breakout supports concurrent reception of four GNSS. This maximizes position accuracy in challenging conditions, increasing precision and decreases lock time; and thanks to the onboard rechargeable 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 Distance Sensor
1.3 Meter, VL53L4CD (Qwiic)
-
This SparkFun Distance Sensor Breakout utilizes the VL53L4CD next generation ToF (Time of Flight) sensor module to give you the highly accurate measurements at short ranges for its size. The VL53L4CD from STMicroelectronics uses a VCSEL (Vertical Cavity Surface Emitting Laser) to emit an infrared laser to time the reflection to the target. That means that you will be able to measure the distance to an object from 1mm to 1300mm away with millimeter resolution! To make it even easier to get your readings, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system so 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.

Si1145 UV / Ambient Light / Proximity Sensor
SEN-36002
-
SEN-36002 is a highly integrated carrier board designed for the Si1145 UV, Ambient Light and Proximity sensor IC from Silicon Labs. This sensor has 100mLUX resolution, and has a dynamic range of 1 LUX to 128 kLUX with IR correction. This means that whether your application is indoors in poor lighting conditions or outside in full sunlight, this sensor has you covered. In addition, we added a high power LED (150mA max, 20 degree) to take full advantage of the proximity sensing capability of this IC - something you won't see on most competitive carrier boards. Integration is easy with 4 x 4-40 sized mounting holes at the corners of the PCB and signal translation to handle interface voltages from 3V to 5V. The board is interfaced via an I2C interface and function pins have been broken out to a 0.1" pin header. The INT pin is also broken out for interrupt capability.
