The Qwiic Dynamic NFC/RFID Tag graduates to reds and the AWS IoT ExpressLink SARA-R5 Starter Kit gets a new version.
SparkX is back with a new NFC/RFID Tag, the FLIR Lepton Breakout V2 is now available on its own, and we have a new and better way to remove a U.FL-terminated cable.
This week the BMP581 Pressure Sensor and ISM330DHCX 6DoF IMU get the Qwiic treatment!
The second part of a series on different technologies that could be used to find missing objects - in this case a lost frisbee.
Last month, we gave you a sneak preview of an upcoming exhibit at the Hong Kong History Museum. The creator, Alexson Chu, was using SparkFun parts and projection mapping to create an interactive learning experience for museum goers. Well, the installation premiered yesterday, and we have an inside look.
Museums are always looking for ways to engage their visitors. See how one artist is using SparkFun parts and projection mapping to make that happen.

The new SparkFun RTK Surveyor is now available from SparkX, along with a new RPi4 Case Fan, Teensy 4 SmartLED Shield, and M6E-NANO RFID Module.
Building a system that records temperature based on a user's unique RFID tag into an Excel spreadsheet for the world of COVID-19.
Let’s talk about RFID technology. Where did it come from? Where is it now? What can you do with it? What did I do with it? Take a look at this video, and all (or at least a tiny bit) will be revealed!
In a new tutorial we'll revisit some RFID basics, and practice by making a remote work logger using an RFID reader and a GPS module.
On this fine Friday we add RFID capabilities to our Qwiic Connect System with a new board and kit, the newest pi-top is available, and a few other knick-knacks to help you out with your next project!
On this fine Friday, we bring you a new NFC-RFID Expansion Board for the Onion Omega, and three skinny, addressable RGBW LED strips!
