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 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.

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.
