The SparkFun GPS-RTK2 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 10 mm, 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 even 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.
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 20 Hz. The GPS-RTK2 even has five communications ports which are all active simultaneously: USB-C (which enumerates as a COM port), UART1 (with 3.3 V 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-RTK2 over the 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.

The Grove DHT11 Temperature & Humidity Sensor is a high-quality, low-cost digital temperature, and humidity sensor based on the DHT11 module. It is the most common temperature and humidity module for Arduino and Raspberry Pi. It is widely favored by hardware enthusiasts for its many advantages such as low power consumption and excellent long-term stability. Relatively high measurement accuracy can be obtained at a very low cost. The single-bus digital signal is output through the built-in ADC, which saves the I/O resources of the control board. Features Dimensions: 40 x 20 x 8 mm Weight: 10 g Battery: Exclude Input Voltage: 3.3 V & 5 V Measuring Current: 1.3 mA- 2.1 mA Measuring Humidity Range: 5% - 95% RH Measuring Temperature Range: -20 ℃ - 60 ℃
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.

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 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. 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.
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-M8U: 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-M8U GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M8U. This reduces the time-to-first fix from a cold start (~26s) to a hot start (~1.5s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.

Maker Line is a line sensor with 5 x IR sensors array that is able to track line from 13 mm to 30 mm width. The sensor calibration is also simplified. There is no need to adjust the potentiometer for each IR sensor. You just have to press the calibrate button for 2 seconds to enter calibration mode. Afterwards you need to sweep the sensors array across the line, press the button again and you are good to go. The calibration data is saved in EEPROM and it will stay intact even if the sensor has been powered off. Thus, calibration only needs to be carried out once unless the sensor height, line color or background color has changed. Maker Line also supports dual outputs: 5 x digital outputs for the state of each sensor independently, which is similar to conventional IR sensor, but you get the benefit of easy calibration, and also one analog output, where its voltage represents the line position. Analog output also offers higher resolution compared to individual digital outputs. This is especially useful when high accuracy is required while building a line following robot with PID control. Features Operating Voltage: DC 3.3 V and 5 V compatible (with reverse polarity protection) Recommended Line Width: 13 mm to 30 mm Selectable line color (light or dark) Sensing Distance (Height): 4 mm to 40 mm (Vcc = 5 V, Black line on white surface) Sensor Refresh Rate: 200 Hz Easy calibration process Dual Output Types: 5 x digital outputs represent each IR sensor state, 1 x analog output represents line position.

Grove is an open-source, modulated, and ready-to-use toolset and takes a building block approach to assemble electronics. This Kit includes a Base Shield to which the various Grove modules can be connected both individually, or together in various combinations to create fun and exciting projects. All of the modules use a Grove connector, which connects each of the components to a Base Shield in just a few seconds. The Base Shield can then be mounted onto an Arduino UNO board and can be programmed using the Arduino IDE. Instructions for connecting and programming the different modules are also included in this kit. This kit was elaborated in collaboration with Seeed Studio and provides the Arduino community with the opportunity to build projects with minimal effort of both wiring and coding. This kit acts as a bridge to the world of Grove and provides a flexible way for Makers to extend their projects to include other complex Grove modules. The Kit comes includes access to an online platform with all the instructions required to plug, sketch and play with the different Grove Modules. Please note: This kit does not include the Arduino Uno board. Included 1 Base Shield that is designed to fit on top of an Arduino UNO board. It comes equipped with 16 grove connectors, which, when placed on top of the UNO, provides the functionality to various pins. It includes: 7x digital connections 4x analog connections 4x I²C connections 1x UART connection 10 Grove modules included can be connected to the base shield, either through the digital, analog, or I2C connectors on the shield. Let's take a quick look at them: The LED - a simple LED that can be turned ON or OFF, or dimmed. The button - pushbutton can either be in a HIGH or LOW state. The potentiometer - a variable resistor that increases or decreases resistance when turning its knob. The buzzer - a piezo speaker that is used to produce binary sounds. The light sensor - a photoresistor that reads light intensity. The sound sensor - a tiny microphone that measures sound vibrations. The air pressure sensor - reads air pressure, using the I²C protocol. The temperature sensor - reads temperature and humidity at the same time. The accelerometer - a sensor used for orientation, used for detecting movement. The OLED screen - a screen that values or messages can be printed to. 6 Grove cables allow you to easily connect the modules to the Base Shield without any soldering required. The Arduino Sensor Kit Library is a wrapper that contains links to other libraries related to certain modules such as the accelerometer, air pressure sensor, temperature sensor, and OLED display. This library provides easy-to-use APIs that will help you build a clear mental model of the concepts you will be using.
