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. Features 1 x Qwiic Connector Integrated U.FL connector for use with an antenna of your choice Concurrent reception of GPS, GLONASS, Galileo and BeiDou 184-Channel GNSS Receiver Receives both L1C/A and L2C bands Horizontal Position Accuracy: 0.20 m with RTK Max Navigation Rate: Up to 30Hz Time to First Fix Cold: 24 s Hot: 2 s Operational Limits Max G: ≤4 G Max Altitude: 50 km Max Velocity: 500 m/s Velocity Accuracy: 0.5 m/s Heading Accuracy: 0.2 degrees Built-In Accelerometer and Gyroscope Time Pulse Accuracy: 30ns Voltage: 5 V or 3.3 V, but all logic is 3.3 V Current: ~85mA to ~130mA (varies with constellations and tracking state) Software Configurable Geofencing Odometer Spoofing Detection External Interrupt Pin Control Low Power Mode Supports NMEA, UBX, and RTCM protocols over UART

Great for sensing pressure (i.e., if it's being squeezed). Flex Sensor (2.2'): As the sensor is flexed, the resistance across the sensor increases. Useful for sensing motion or positioning. SoftPot: These are very thin variable potentiometers. By pressing on various positions along the strip, you vary the resistance. Mini Photocell: The photocell will vary its resistance based on how much light it's exposed to. Will vary from 1kΩ in the light to 10kΩ in the dark. PIR Motion Sensor: Easy-to-use motion detector with an analog interface. Power it with 5-12VDC, and you'll be alerted of any movement. QRD1114 Optical Detector/Phototransistor: An all-in-one infrared emitter and detector. Ideal for sensing black-to-white transitions or can be used to detect nearby objects. IR Diode: This LED can handle up to 50mA of current and outputs in the 940-950nm IR spectrum. Use to send signal to talk to the included IR receiver diode or just turn off your neighbor's TV. IR Receiver Diode: This simple IR receiver will detect an IR signal coming from a standard IR remote control or the IR diode included in the kit. Resistor 1.0M Ohm 1/4 Watt PTH: Two 1/4 Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and perf boards. The large resistor helps dampen any voltage spikes when using the large piezo vibration sensor with a microcontroller.

Commonly used in breadboards and perf boards, these 330Ω resistors make excellent current-limiting resistors for LEDs. SparkFun 9DoF IMU Breakout – ISM330DHCX, MMC5983MA (Qwiic): This breakout board includes a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer. Connect this board over I2C using a Qwiic cable or solder wires or headers to the SPI pins to get started using one of the three sensors or using all three together to determine 3D orientation. SparkFun Atmospheric Sensor Breakout – BME280 (Qwiic): The SparkFun BME280 Atmospheric Sensor Breakout is an easy way to measure barometric pressure, humidity, and temperature readings, all without taking up too much space. SparkFun Indoor Air Quality Sensor – ENS160 (Qwiic): The SparkFun ENS160 Indoor Air Quality Sensor is a digital multi-gas sensor solution with four sensor elements that can be used in a wide range of applications including building automation, smart home, and HVAC. SparkFun Capacitive Touch Slider – CAP1203 (Qwiic): This little board acts great as a non-mechanical button. Use the three pads on the board or connect your own input for a great touch button or slider with no moving parts. Flexible Qwiic Cable (100 mm): Use these to connect up to four Qwiic boards in your kit. RGB and Gesture Sensor (APDS-9960): This board does a little bit of everything. You can measure ambient light or color as well as detect proximity and do gesture sensing all over I2C. Soil Moisture Sensor (with screw terminals): Ever wonder if your plant needs water? This sensor outputs an analog signal based on the resistance of the soil. Since water is conductive, the soil water content will be reflected in the soil resistance. Sound Detector: Ever need to know if there is noise in an area? This board will not only tell you, but it will also output amplitude as well as the full audio signal. Break Away Headers (Straight): Solder these pins to any of the breakouts to prototype on a breadboard. You'll want to solder these to boards that do not have Qwiic connectors such as the gesture sensor and sound detector.

Grove Piezo Vibration Sensor is suitable for measurements of flexibility, vibration, impact and touch. The module is based on PZT film sensor LDT0-028. When the sensor moves back and forth, a certain voltage will be created by the voltage comparator inside of it. Therefore, outputs high & low levels. In spite of the fact that it has a high receptivity for strong impacts, a wide dynamic range (0.001 Hz~1000 MHz) also guarantees excellent measuring performance. Finally, you can adjust its sensitivity by adjusting the potentiometer with a screw.
