We have a rather unique slew of new products this week including Qwiic PIR Kits, a Satellite Transceiver Breakout, GNSS-RTK Accessories, CNC Machines, and more!
Two new kits for MyoWare 2.0 are now available along with new Carbide 3D products and a few odds and ends!
Check out our new QuickLogic Thing Plus FPGA board, or one of the eight new Shapeoko 4 products we just got in stock!
A new soldering kit for beginners, a soft circuits kit from ChickTech, an updated version of the OpenMV, two GPS/GNSS antennas and parts for your CNC!
Two new Qwiic IR Array breakouts, a load of new CNC drills and four different types of copper clad!
The SparkFun Pi AVR Programmer HAT is here, along with new load cells, microSD cards and APA102C LEDs
A large Summer Solstice Sale, a new 3D printer, five new CNC machines, and three little sensor boards. It's a big Friday!

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…

Nice initiative Dryw! But there's something a bit off in the "5V resistor value" calculations, supposedly using Ohm's law. The forward…
