Feather-Sized Evo M51 Board Combines Atmel SAMD51 MCU with Intel MAX 10 FPGA
Arduino unveiled its first FPGA board around two years ago with MKR Vidor 4000 combining an Intel Cyclone FPGA with Microchip SAMD21 Cortex-M0+ MCU in a form factor similar to Arduino Zero.
But in case you are looking for an even smaller Arduino compatible FPGA board, Alorium Technology’s Evo M51 might be exactly what you are after. The Adafruit Feather-sized board is equipped with an Atmel SAMD51 Arm Cortex-M4F microcontroller coupled with an Intel MAX 10 FPGA.

Arduino Security Primer
In order to save memory and improve security, our development team has chosen to introduce a hardware secure element to offload part of the cryptography algorithms computational load, as well as to generate, store, and manage certificates. For this reason, on the Arduino MKR family, Arduino Nano 33 IoT and Arduino Uno WiFi Rev2, you will find the secure element ATECC508A or ATECC608A manufactured by Microchip.

This puck-slapping robot will beat you in table hockey
Mechanical table hockey games, where players are moved back and forth and swing their sticks with a series of knobs, can be a lot of fun; however, could one be automated? As Andrew Khorkin’s robotic build demonstrates, the answer is a definite yes — using an Arduino Mega and a dozen stepper motors to score goals on a human opponent.

A History of my Mechanical Keyboards
Years ago, at a white elephant Christmas party, I ended up with leopard print keyboard stickers. I bought a new keyboard to get the most out of these stickers, and used it for months as the stickers began to wear off. However, the space bar broke in less than a year. I had gone through many keyboards over the years, and all of them had been disappointing with their disposable build quality and lack of longevity. I decided to try a Das Keyboard Ultimate. It was my first foray into the world of mechanical keyboards, and would lead to many years of trying different key switches and purchasing custom key caps. This post is a brief history of the various mechanical keyboards I’ve bought, sold and given away over the years.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
