NXP i.MX RT crossover processors combine real-time capabilities of microcontrollers with the performance of application processors thanks to an Arm Cortex-M7 core clocked at 528 MHz and more. The performance is indeed impressive as shown by Teensy 4.0 benchmarks, but so far NXP i.MX RT processor targeted general purpose applications. The company has now introduced three new crossover processors designed for AI applications. NXP i.MX RT106F is designed for offline face recognition and expression Identification, while RT106L and RT106A are made for local and cloud-based embedded voice applications.

FriendlyELEC ZeroPi is a Tiny Allwinner H3 SBC with Gigabit Ethernet & USB, an Optional SPI Flash
Several years ago, FriendlyELEC launched NanoPi NEO board with Allwinner H3 quad-core Cortex-A7 processor followed by NanoPi NEO2 upgrading to the Allwinner H5 64-bit Arm Cortex-A53 processor. Both boards target low-cost headless applications with I/O headers, USB and Ethernet, but while the NEO2 comes with Gigabit Ethernet, NEO SBC only features 10/100M Ethernet. The company has now been working on a new family of boards called ZeroPi that’s very similar to NanoPi NEO boards, but they do not come with any I/O headers, and the first ZeroPi board features Allwinner H3 processor, and Gigabit Ethernet. ZeroPi specifications with highlights in bold or stricken-through showing differences against NanoPi NEO: SoC – Allwinner H3 quad-core Cortex A7 @ 1.2 GHz with an Arm Mali-400MP2 GPU System Memory – 256 or 512 MB DDR3 Storage – MicroSD card slot, unmounted SPI flash Connectivity – Gigabit Ethernet via Realtek RTL8211E PHY USB – 1x […]
How to Easily Calibrate Retraction in 3D Printers
[Update July 2020: It is now recommended to use Calibration Generator program instead of the Google Doc Spreadsheet in this article] Hey, Karl here with a short article on retraction tuning. I really enjoy reviewing 3D printers and all things 3D printing with one exception…. when I have to calibrate retraction (aka retraction tuning). It takes so much time. What is Retraction? While 3D printing on a standard FDM printer, the filament is pushed with an extruder motor that has a gear attached. It pushes the filament, either directly into the hotend assembly or through a Bowden tube to the hotend. Molten plastic is then layered to produce a model. When it is printing nearly all prints require non-extruding movements. During the extruding moves pressure builds up and in order to stop stringing and blobbing during non-printing moves, a retraction happens. There are 2 main variables that affect this: the […]
USB4 Specification Released, Up to 40 Gbps Data Transfer Rate Supported
USB 3.2 was announced about two years ago with speeds of up to 20 Gbps using existing USB 3.1 Gen 2 USB-C cables, but the USB Implementers Forum has done a bit work more and just released the USB4 specification allowing twice the speed at 40 Gbps. The USB4 architecture leverages the Thunderbolt protocol specification that was recently contributed by Intel Corporation to the USB Promoter Group, enables the faster data rate, as well as multiple simultaneous data and display protocols. Highlights of USB4 standard Two-lane operation using existing USB Type-C cables and up to 40Gbps operation over 40Gbps certified cables Multiple data and display protocols that share the maximum aggregate bandwidth Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3 Up to 100 Watts power delivery Both USB 3.2 and USB4 require USB-C cables to make use of the maximum transfer rate, so traditional USB cables may fade […]
Microsoft Unveils The Vision AI Developer Kit For AI on the Edge
The field of Artificial Intelligence is getting more exciting every single day, and the big corporations and startups are massively pouring for it. One thing I am undoubtedly sure about is that the future will certainly be remarkable. Microsoft, the biggest software company in the world with sales over $100 billion has been venturing in the domain of artificial intelligence for a while now with cloud computing platform Azure and other related cloud computing services, but instead of its usual cloud computing route for AI, Microsoft is banking on AI on the edge with the introduction of the Vision AI Developer Kit in joint partnership with the semiconductor giant Qualcomm. With millions of data collected at the Edge, the potential of artificial intelligence on the edge is promising. AI cases performed on the Edge will help in making critical decisions, and more data insight can even facilitate important business scenarios. […]
