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.
On this fine Friday, we bring you a new NFC-RFID Expansion Board for the Onion Omega, and three skinny, addressable RGBW LED strips!

That's true, the blue LEDs would ideally have a resistor closer to 4x than 2x when jumping from 3.3V to 5V. I don't remember my original…
Thanks for your reply! Your "roughly double" resistances for 5V vs 3.3V imply that the difference between LED drop and 3,3V is same as 3,3V…
Your right, that would be a great way to fine tune the current for LEDs! You're also correct that the goal of this project was finding the…
Hi there! For the sake of brevity, I didn't go into full detail about how exactly I calculated the 5V resistor values. But in short, I took…
