Looking to easily expand the capabilities of your Raspberry Pi, NVIDIA Jetson or Google Coral? Just throw a HAT on!
Every major development board or single board computer has their own version of add-on boards: Arduino has shields, Beagle has capes, and Raspberry Pi has HATs (Hardware Attached on Top). Here at SparkFun, we have our own line of boards that can be used in robotics, machine learning applications and everything in between. Not only will these boards easily attach to a Raspberry Pi, they will also work with the NVIDIA Jetson Nano and Google Coral, as well as any other development platform with a 2x20 header.
pHATs are stack-ons that fit neatly on a Raspberry Pi, Jetson Nano, or Google Coral. They quickly add functionality to your single-board computer without soldering - use one, or stack them. With aligned mounting holes, they also make it easy to add accessories such as camera, display cables, or the entire Qwiic Connect System.
The GPS-RTK Dead Reckoning pHAT adds extremely accurate GPS and GNSS capabilites.
The SparkFun Top pHAT supports machine learning interactions.
The SparkFun Auto pHAT adds robotics functionality, fast.
The SparkFun Pi AVR Programmer HAT makes it easy to program AVRs directly from the SPI hardware pins on any Raspberry Pi.
SparkFun also has a few more stack-on items you may be interested in.
The SparkFun Qwiic pHAT Extension for the Raspberry Pi 400 provides you with a quick and easy solution to access all of the 400's GPIO, stack your favorite HAT right-side up, or connect a Qwiic-enabled device to the I2C bus (GND, 3.3V, SDA, and SCL). Since the Qwiic system allows for daisy-chaining boards with different addresses, you can also stack as many sensors as you’d like to the mounting holes on the pHAT to create a tower of sensing power!Buy the Qwiic pHAT Extension for Raspberry Pi 400
Similar to the Qwiic pHAT above, this Qwiic HAT hangs off the the edge of your single board computer and breaks out out the GPIO pins, allowing you access to them in order to customize your specific project.Buy the Qwiic HAT
The SparkFun Qwiic SHIM is a small, easily removable breakout that adds a Qwiic connector to your Raspberry Pi or other single board computer. The SHIM design allows you to plug directly to the Pi's I2C bus with no soldering, and the thin PCB design allows for it to be sandwiched on your Pi GPIO with other HATs! The Qwiic SHIM works great when you do not need the full capabilities of the Qwiic pHAT for Raspberry Pi, or if you want to add a Qwiic connector to your Pi but do not have room for yet another HAT.Buy the Qwiic SHIM
The SparkFun Pulsed Radar A111 Breakout features a single-chip solution for pulsed coherent radar (PCR), and comes complete with an integrated antenna and an SPI interface capable of clock speeds of up to 50MHz. Though the A111's primary use case is distance-sensing, it also supports applications in gesture, motion, material and speed detection at distances of up to two meters.Buy the Pulsed Radar Breakout
