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 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 if you prefer to use a breadboard. We've included a rechargeable backup battery to keep the latest module configuration and satellite data available for up to two weeks. This battery helps 'warm start' the module decreasing the time-to-first-fix dramatically. This module features a survey-in mode allowing the module to become a base station and produce RTCM 3.x correction data. Based on your feedback, we switched out the u.FL connector and included an SMA connector in this version of the board. The number of configuration options of the ZED-F9P is incredible! Geofencing, variable I²C address, variable update rates, even the high precision RTK solution can be increased to 20Hz. The GPS-RTK2 even has five communications ports which are all active simultaneously: USB-C (which enumerates as a COM port), UART1 (with 3.3V TTL), UART2 for RTCM reception (with 3.3V TTL), I²C (via the two Qwiic connectors or broken out pins), and SPI. SparkFun has also written an extensive Arduino library for u-blox modules to easily read and control the GPS-RTK-SMA over our Qwiic Connect System. Leave NMEA behind! Start using a much lighter weight binary interface and give your microcontroller (and its one serial port) a break. The SparkFun Arduino library shows how to read latitude, longitude, even heading and speed over I²C without the need for constant serial polling. Features Concurrent reception of GPS, GLONASS, Galileo and BeiDou Receives both L1C/A and L2C bands Voltage: 5 V or 3.3 V, but all logic is 3.3 V Current: 68 mA - 130 mA (varies with constellations and tracking state) Time to First Fix: 25 s (cold), 2 s (hot) Max Navigation Rate: PVT (basic location over UBX binary protocol) - 25 Hz RTK - 20 Hz Raw - 25 Hz Horizontal Position Accuracy: 2.5 m without RTK 0.010 m with RTK Max Altitude: 50 km Max Velocity: 500 m/s Weight: 6.8 g Dimensions: 43.5 mm x 43.2 mm 2 x Qwiic Connectors
This exceptional GPS/GNSS antenna is designed for both GPS and GLONASS reception. The magnetic mount allows it to be easily mounted to a metal base such as a ground plate or car roof. The antenna is terminated with a 3m cable and standard SMA connector.

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), making 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 if you prefer to use a breadboard. The NEO-M9N module detects jamming and spoofing events and can reports them to the host so that the system can react to such events. A SAW (Surface Acoustic Wave) filter combined with an LNA (Low Noise Amplifier) in the RF path is integrated into the NEO-M9N module, allowing normal operation even under strong RF interferences. U-blox based GPS products are configurable using the popular but dense, windows program called u-centre. Plenty of different functions can be configured on the NEO-M9N: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. All of this can be done within the SparkFun Arduino Library! The SparkFun NEO-M9N GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M9N. This reduces the time-to-first fix from a cold start (~24s) to a hot start (~2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.

The Triad is made up of three sensors; the AS72651, the AS72652, and the AS72653, and can detect light from 410nm (UV) to 940nm (IR). Besides, 18 individual light frequencies can be measured with precision down to 28.6 nW/cm² and an accuracy of +/-12%. 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 if you prefer to use a breadboard. The SparkFun Triad Spectroscopy Sensor communicates over I²C by default or over 115200bps serial. We've written a fully formed Arduino library to access all the various features include taking readings and illuminating LEDs all over the Qwiic I²C interface. Also, the Triad can be set up to communicate over serial. The serial interface uses an AT command set. What can you do with light spectroscopy? It’s an amazing field of study, and the SparkFun Triad brings what used to be prohibitively expensive equipment to the desktop. The AS7265x should not be confused with highly complex photon spectrometers. Still, the sensor array gives the user the ability to measure and characterize how different materials absorb and reflect 18 different light frequencies. We've also written a full Arduino library that makes reading and interacting with the Triad simple and easy! Features Selectable interface: I²C or Serial (115200bps) 18 frequencies of light-sensing from 410 nm to 940 nm 28.6 nW/cm² per count Accuracy of +/-12% Integrated 405nm UV, 5700k White, and 875nm IR LEDs Software control over each illumination LED as well as current control Optional external bulb or illumination control Programmed with the latest firmware from AMS

We've provided a Qwiic connector to connect to the I²C data lines easily, but you will also need to connect to two additional lines. This board is tiny, measuring 25.4 mm x 12.7 mm, which means it will fit nicely on your finger without all the bulk. The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664, which applies its algorithms to determine heart rate and blood oxygen saturation (SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting and a handy finger detection data point. To get the most out of the sensor, Sparkfun has written an Arduino Library to make it easy to adjust all the possible configurations. Features SparkFun Pulse Oximeter and Heart Rate Sensor MAX30101 and MAX32664 sensor and sensor hub Qwiic connectors for power and I²C interface I²C Address: 0x55 MAX30101 - Pulse Oximeter and Heart-Rate Sensor Heart-Rate Monitor and Pulse Oximeter Sensor in LED Reflective Solution Integrated Cover Glass for Optimal, Robust Performance Ultra-Low Power Operation for Mobile Devices Fast Data Output Capability Robust Motion Artifact Resilience MAX32664 - Ultra-Low Power Biometric Sensor Hub Biometric Sensor Hub Solution Finger-Based Algorithms Measure Pulse Heart Rate and Pulse Blood Oxygenation Saturation (SpO2) Both Raw and processed data are available. Basic Peripheral mix optimizes size and performance.
The NEO-M8U module is a 72-channel u-blox M8 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~2.5-meter accuracy. The module supports the concurrent reception of three GNSS systems. The combination of GNSS and integrated 3D sensor measurements on the NEO-M8U provide accurate, real-time positioning rates of up to 30Hz. Compared to other GPS modules, this breakout maximizes position accuracy in dense cities or covered areas. Even under poor signal conditions, continuous positioning is provided in urban environments and is also available during complete signal loss (e.g. short tunnels and parking garages). With UDR, position begins as soon as power is applied to the board, even before the first GNSS fix is available! Lock time is further reduced with an on-board 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), making it perfect for the Qwiic compatibility, so we don't have to use up our precious UART ports.

The VL53L1X 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 40mm to 4m 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. Each VL53L1X sensor features a precision to be 1mm with an accuracy around +/-5mm, and a minimum read distance of this sensor is 4cm. The field of view for this little breakout is fairly narrow at 15°-27° with a read rate of up to 50Hz. Make sure to power this board appropriately since it will need 2.6V-3.5V to operate. Lastly, please be sure to remove the protective sticker on the VL53L1X before use otherwise it will, most assuredly, throw off your readings. Features Operating Voltage: 2.6V-3.5V Power Consumption: 20 mW @10Hz Measurement Range: ~40mm to 4,000mm Resolution: +/-1mm Light Source: Class 1 940nm VCSEL 7-bit unshifted I²C Address: 0x29 Field of View: 15° - 27° Max Read Rate: 50Hz
The ZED-F9R module is a 184-channel u-blox F9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~0.2-meter accuracy! That's right; such accuracy can be achieved with an RTK navigation solution when used with a correction source. Note that the ZED-F9R can only operate as a rover, so you will need to connect to a base station. The module supports the concurrent reception of four GNSS systems. The combination of GNSS and integrated 3D sensor measurements on the ZED-F9R provide accurate, real-time positioning rates of up to 30Hz. Compared to other GPS modules, this pHAT maximizes position accuracy in dense cities or covered areas. Even under poor signal conditions, continuous positioning is provided in urban environments and is also available during complete signal loss (e.g. short tunnels and parking garages). The ZED-F9R is the ultimate solution for autonomous robotic applications that require accurate positioning under challenging conditions. This u-blox receiver supports a few serial protocols. By default, we chose to use the Raspberry Pi's serial UART to communicate with the module. With pre-soldered headers, no soldering is required to stack the pHAT on a Raspberry Pi, NVIDIA Jetson Nano, Google Coral, or any single-board computer with the 2x20 form factor. We have also broken out a few 0.1'-spaced pins from the u-blox receiver. A Qwiic connector is also added in case you need to connect a Qwiic enabled device. U-blox based GPS products are configurable using the popular but dense, windows program called u-centre. Plenty of different functions can be configured on the ZED-F9R: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. The SparkFun ZED-F9R GPS pHAT is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZED-F9R. This reduces the time-to-first fix from a cold start (~24s) to a hot start (~2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.
