Introducing the Arduino Portenta H7

Designed for demanding industrial applications, AI edge processing, and robotics, the Arduino Portenta family is a new standard for open high-density interconnect to support advanced peripherals.

The first member of the family is the Portenta H7 module – a dual-core Arm Cortex-M7 and Cortex-M4 operating at 480MHz and 240MHz, respectively, with an operational temperature range of -40 to 85°C. The Portenta H7 is capable of running Arduino code, Python, and JavaScript, making it accessible to an even broader audience of developers.

STM32 Blue Pill vs Black Pill Microcontroller Boards

The “Blue Pill” is a cheap STM32 Cortex-M3 based microcontroller board. It is popular because of its price and versatility. Now there is an updated variant, dubbed the “Black Pill” with a new STM32 microcontroller based on the Cortex-M4F (with a FPU).

The Blue Pill uses the STMicro STM32F103C8T6 and costs less than $2. The new “Black Pill” is shipping in two variants, one using the STM32F401CCU6, the other using STM32F411CEU6. Both are Arm Cortex-M4F based microcontrollers.

Watch these overclockers crank Intel’s Core i9 10900K all the way to 7.7GHz

For the time being, the highest validated overclock for Intel’s brand new Core i9 10900K Comet Lake CPU is just over 7.7GHz, achieved by a team of enthusiasts with tubs of liquid helium at their disposal. Suffice to say, don’t try this at home.

Professional overclocker Elmor and his team certainly didn’t. Sequestered in a lab at Asus’s headquarters, Elmor and the gang got busy dumping a steady supply of liquid helium into a pot attached to an Asus ROG Maximus XII Apex motherboard, which is built for this sort of thing.

AMD B550 Motherboards Announced: PCIe 4.0 Support for as Little as $100

With AMD’s new mainstream Ryzen 3 3000 CPUs hitting our test bench a couple of weeks ago and Vega-packing Ryzen 4000 Renoir desktop chips seemingly waiting in the wings, now is as good a time as any for new affordable AMD motherboards. Board makers have recently been busy rolling out to Intel-based Z490 boards. But those same companies are also about to usher in a slew of B550 boards (announcing today and going on sale starting June 16) for recent AMD processors that bring most of the key features (like PCIe 4.0 support) of the higher-end X570 platform that launched last year at lower price points that start at $100.

Adventures with solderless 3D printed circuits + conductive filament

I had in my possession some X3D conductive ABS. The question begged: Could I create a 3D printed PCB that didn’t use a soldering iron? Yes!
Well, sort of..

I certainly learned a lot making this video but the conductive filament isn’t quite up to the task, based on my experiences and those I reviewed of others.
This filament was supplied to me free of charge by my filament sponsor X3D. It was my choice to make the video and all opinions expressed are my own.

ZFS versus RAID: Eight Ironwolf disks, two filesystems, one winner

This has been a long while in the making—it’s test results time. To truly understand the fundamentals of computer storage, it’s important to explore the impact of various conventional RAID (Redundant Array of Inexpensive Disks) topologies on performance. It’s also important to understand what ZFS is and how it works. But at some point, people (particularly computer enthusiasts on the Internet) want numbers.
