SPEed Up The Future! Join the Single Pair Ethernet (SPE) Design Challenge. Build an original application for 10BASE-T1L SPE for a chance to win fantastic prizes!
We are off this weekend in observation of the final nights of Hanukkah and Christmas! We'll be back on Tuesday, December 27th!
This graphic-based story provides an image-driven overview of 10BASE-T1L Single-Pair Ethernet (SPE), which helps facilitate the use of predictive maintenance, Industrial IoT (IIoT), and the gathering of meaningful operational data for automation across the entire industrial enterprise.
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…
Responding to your note about the highly non-linear relationship between the pot position and the current -- a way to address this would be…
Nice initiative Dryw! But there's something a bit off in the "5V resistor value" calculations, supposedly using Ohm's law. The forward…
Minor issue: "Today's Deals" is still showing SparkFun Level Shifting microSD Breakout and…
That was fun to watch. Now to figure out how to ship the boards, inexpensively.
That was awesome...and exhausting! Keep up the great work, Sparkfun!

I know a guy who is a big "fan" of IoT, even though he's not all that technical. His "day job" is as a business attorney, so he can afford a…
