SparkFun Pressure Sensor Breakout
MS5803-14BA
-
This is the MS5803-14BA Pressure Sensor Breakout, a high resolution pressure sensor with both an I2C and SPI interface. This MEMS pressure sensor measures the absolute pressure of the fluid around it which includes air, water, and anything else that acts like a viscous fluid. Depending on how you interpret the data, you can determine altitude, water depth, or any other tasks that require an accurate pressure reading. What makes the MS5803-14BA unique is the the gel membrane and antimagnetic stainless steel cap that protects against 30 bar water pressure.

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.

TMD37003 cRGB Color and Proximity Sensor
SEN-36004
-
Fully integrated carrier board designed to get the most out of the TMD37003 cRGB (color with IR compensation) and Proximity Sensor from AMS. This means that the board includes a 1.8V-5V input range LDO and high-speed signal voltage translation on all IO pins. In addition, we've added a high output white LED that is tuned to the light temperature range of the TMD37003 IC. This makes sensing color of close-proximity objects possible, such as in robotic color sorting operations. As on many of our boards, we've included 4-40 sized mounting holes to make installation easy. The IC functions are interfaced via a 0.1" header, which includes power (Vdd and GND), I2C interface (again, fully translated) and a 3.3V input to power the proximity (IR) LED. The on-board LED is turned on with a logic 'HIGH' applied to the LED pin and is powered with Vdd.

The SparkFun NEO-M9N GPS Breakout with on-board chip antenna 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 witn ~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.

ArgoBot Kit
ROB-00001
-
The ArgoBot Full Kit is a fully assembled robot and controls development platform. It is based on the Digilent chipKIT WF32(TM), a WiFi enabled development platform, and configured for LabVIEW targeting. Most importantly ArgoBot was designed with FIRST Robotics Competition teams in the front of our minds! Named after the FRC Team 1756 mascot, Argos, the ArgoBot development platform includes a fully-assembled, ready to drive mini WiFi enabled robot (about 8" x 5" x 4"), as well as tons of FRC controls tutorials and example code (LabVIEW VIs). Features included on the ArgoBot will look very familiar to anyone who has worked with National Instruments products (Compact RIO and RoboRIO) in the past. This includes three 5V Digital I/O modules (with jumpered pull-ups), three 5V analog inputs, and an I2C header. Example VIs have been streamlined to enable a 1-click configuration style to accelerate your development process. We also added a 2-channel motor driver that is used to supply the ArgoBot drive motors. Our ultimate goal is that everything you can build, control or implement on ArgoBot can be easily leveraged on your FRC bot! Complimenting its many electrical features, ArgoBot is easy to work with and easy to maintain. The chassis is a polycarbonate (the extremely tough stuff that is easy to drill and modify but easily takes bumps and bruises without cracking) case that is fully intact - meaning that ArgoBot doesn't just come with a case... it is a case! Clean-up and organization is simple - just close the case and turn off the power switch.
