Raspberry Pi HATs

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.

Raspberry Pi 4 was welcomed by the Pi enthusiasts for the increased processing power. However, this came at a price. The RPi 4 can draw up to 3 Amps, which means it has to dissipate 15 W of power. Raspberry Pi cooling is a must. From the simplest passive heat sink, through elaborate fan blowers and even to an exotic water-cooled idea, many options are available.The Smart Fan has the form factor of the Raspberry Pi HAT. Its own tinny 32-bit processor receives commands from Raspberry Pi through the I²C interface. A step-up power supply converts the 5 V provided by Raspberry Pi to 12 V, ensuring precise speed control. Using pulse width modulation, it powers the fan just enough to maintain a constant temperature of the Raspberry Pi processor.The Smart Fan preserves all the GPIO pins, allowing any number of cards to be stacked on top of Raspberry Pi. If another add-on card has to dissipate power, a secondary Smart Fan can be added to the stack.DIN-Rail MountingTogether with multiple add-on cards, the Smart Fan can be installed on the DIN-Rail, for sturdy industrial applications.Stack Level JumperTwo Smart Fans can be installed on top of each Raspberry Pi. The assumption is that you have one more card in the stack which requires cooling. The bottom side of the Smart Fan has a jumper which needs to be installed on the second fan, in order for the Raspberry Pi to differentiate the two I²C addresses.Features 40 x 40 x 10 mm fan with 6 CFM airflow Step-up 12 V power supply for precise fan speed control PWM Controller modulates the fan to keep constant Pi temperature Draws less than 100 mA of power Stackable to itself, 2 fans can be added to Raspberry Pi Fully stackable allows adding other cards to Raspberry Pi Uses only I²C interface, leaves full use of all GPIO pins Super quiet and efficient Included Smart Han HAT 40 x 40 x 10 mm Fan with mounting Screws Mounting Hardware Downloads User's Guide Open Source Hardware Schematic 2D CAD Drawing Command line Python Libraries Node-Red Nodes

The servo control is based on the SparkFun servo pHAT, and thanks to its I2C capabilities, this PWM add-on saves the Raspberry Pi's GPIO pins, allowing you to use them for other purposes. We have also provided a Qwiic connector for easy interfacing with the I²C bus using the Qwiic system. Whether you use the Auto pHAT with a Raspberry Pi, NVIDIA, Jetson Nano, Google Coral, or other SBC, it makes for a unique robotics addition and board with a 2x20 GPIO. The DC motor control comes from the same 4245 PSOC and 2-channel motor ports system used on the SparkFun Qwiic Motor Driver. This provides 1.2A steady-state drive per channel (1.5A peak) and 127 levels of DC drive strength. The SparkFun Auto pHAT also supports up to two motor encoders thanks to the onboard ATTINY84A to provide more precise movement to your creation! Additionally, the Auto pHAT has an on-board ICM-20948 9DOF IMU for all your motion-sensing needs. This enables your robot to access the 3-Axis Gyroscope with four selectable ranges, 3-Axis Accelerometer, again with four selectable ranges, and 3-axis magnetometer with an FSR of ±4900µT. Power to the SparkFun Auto pHAT can be supplied through a USB-C connector or external power. This will power either the motors only or power the motors and the Raspberry Pi that is connected to the HAT. We've even added power protection circuits to the design to avoid damage to power sources. Features 4245 PSOC and 2-channel motor ports programmable using Qwiic library Onboard ATTINY84A supports up to two DC motor encoders 5V pass-through from RPi Onboard ICM-20948 9DOF IMU for motion sensing accessible via Qwiic library PWM control for up to four servos Qwiic connector for expansion to full SparkFun Qwiic ecosystem Designed for stacking, full header support & can use additional pHATs on top of it Uninhibited access to the RPi camera connector & display connector. USB-C for powering 5V rail (Motors/Servos/back powering Pi) External power inputs broken out to PTH headers

Add global GSM connectivity and GPS tracking to your project with a BerryGPS-GSM. This is an all in one module which can provide location tracking and GSM services such as data, text and SMS to your project. It comes in the same form factor as a Raspberry Pi Zero, which makes it nice and compact when used with a Raspberry Pi Zero. The two main components that make this board great are; uBlox CAM-M8 GPS module (Same GPS found on BerryGPS-IMU V3) uBlox SARA-U201 GSM for GSM connectivity, which has global coverage. Both of these modules working together results in obtaining a GPS fix in secs, using Assisted GPS. Typically, a GPS module can take a few minutes to get Time To First Fix(TTFF), or even longer if you are in built up areas. This is because the Almanac needs to be downloaded from satellites before a GPS fix can be acquired and only a small portion of the Almanac is sent in each GPS update. Assisted GPS speeds this up significantly by downloading ephemeris, almanac, accurate time and satellite status over the network, resulting in faster TTTF, in a few seconds. This is very similar how to GPS works on a smartphone. BerryGPS-GSM has been designed for the Raspberry Pi Zero, however it works with all versions of Raspberry Pi. We have created a USB-to-USB PCB connector to be used with a Raspberry Pi Zero, which is designed to make your project more compact.
