We've assembled this annotated resource list to better understand Matter and Thread - what it is, why it matters, and use cases.
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!
The Qwiic Dynamic NFC/RFID Tag graduates to reds and the AWS IoT ExpressLink SARA-R5 Starter Kit gets a new version.
Sandeep Mistry uses a SparkFun AzureWave Thing Plus to combine real-time audio, AI/ML, DSP, and Wi-Fi connectivity technologies together to get notified when your doorbell rings while you're away.
Happy Women's History Month! Today we're sharing the story of Hedy Lamarr, who was a Hollywood actress in the 1940s as well as an inventor who holds the patent for frequency hopping, which is used in wireless communications today like WiFi and Bluetooth!
Yesterday, we released the Thing+ Matter. Today, we take a look at it and the rest of our new products for the week!
The first easily accessible board that combines Matter and SparkFun’s Qwiic ecosystem for new IoT development is here!
Two new Air Velocity Sensor Qwiic Kits are now available! Also be sure to check out the new Raspberry Pi Debug Probe and Kitronik Servos Board, too!
Computer scientist and engineer Mark Dean is credited with helping develop multiple major technologies, among them the Industry Standard Architecture system bus, the color PC monitor and the first gigahertz chip. Learn more about his history with IBM and his breakthroughs in computer engineering here!
Two new IN100 NanoBeacon Boards are now available with the newest versions of our Cerberus USB Cables.
This year, SparkFun turns 20. Take a look back with us at the last two decades and share what our top products were each year! Which ones do you have in your workshop?
A new Analog MEMs Microphone Breakout is now available as well as two new 5V Buck Regulators.
February is Black History Month, and we want to take some time to highlight the work of black scientists and engineers whose work influences our industry and the world around us.
