Arduino Portenta H7 Gets Embedded Vision Shield with Ethernet or LoRa Connectivity

[Update January 28, 2021: The LoRa version of Portenta Vision Shield is now available] Announced last January at CES 2020, Arduino Portenta H7 is the first board part industrial-grade “Arduino Pro” Portenta family. The Arduino MKR-sized MCU board has plenty of processing power thanks to STMicro STM32H7 dual-core Arm Cortex-M7/M4 microcontroller. It was launched with a baseboard providing access to all I/Os and ports like Ethernet, USB, CAN bus, mPCIe socket (USB), etc… But as AI moves to the very edge, it makes perfect sense for Arduino to launch Portenta Vision Shield with a low-power camera, two microphones, and a choice of wired (Ethernet) or wireless (LoRA) connectivity for machine learning applications. Portenta Vision Shield key features and specifications: Storage – MicroSD card socket Camera – Himax HM-01B0 camera module with 324 x 324 active pixel resolution with support for QVGA Image sensor – High sensitivity 3.6μ BrightSense pixel technology […]

Mini replica of DEC PDP-11 computer runs 2.11 BSD UNIX on ESP32 SoC

The relatively popular Digital Equipment Corporation (DEC) PDP-11 16-bit minicomputers started selling in the 70s, and were still available in the earlier 90s. While being stuck in Europe due to COVID-19 restrictions, Jeroen Domburg (aka Sprite_tm) decided to design a tiny replica of a DEC VT102 PDP-11 terminal based on ESP32 wireless SoC and running 2.11 BSD UNIX through SimH PDP11 emulator. Jeroen had to do significant work to make SimH works on ESP32 however, with notably the need to optimize the memory footprint: Obviously, ‘just port SIMH to an ESP32’ is a bit of a understatement for the effort that was needed. Even while SIMH is a pretty nice program when it comes to not using any unique APIs, it still is a system developed for a full-blown workstation and assumes RAM is cheap and plentiful. In order to get it running on an ESP32 and still have some […]

NextDFM software detects PCB design problems before manufacturing (Sponsored)

Shenzhen Huaqiu Electronics Co., Ltd, better known as NextPCB, is a PCB manufacturer with multiple factories in China, and that has been around for over 15 years. During this time, the company dealt with thousands of engineering problems of PCB leading to higher prices and delayed schedules. So to help its customers, the company has developed NextDFM software to detect common PCB design problems, and ultimately help engineers to build low-cost and high-efficiency PCB projects. DFM stands for “Design For Manufacturability”, glad you asked. NextPCB is a free download that’s available for Windows only for now, but the company is also working on Linux and Mac OS versions that will be released in the future. The software supports generic Gerber files as well as PCB layout files from EDA programs such as Altium, Pads, and Protel99SE. Once your file is loaded in the program you’d be able to run the […]
