International Black Friday 2022 deals and coupons

GeekBuying

We’ve been writing about international Black Friday and Cyber Monday deals and coupons since 2014, since US-centric promotions such as Amazon Black Friday deals are not always suitable to the diverse, international audience of CNX Software. Let’s check out Black Friday 2022 international deals from specific manufacturers as well as events from Aliexpress, Banggood, and other stores. Arduino Black Friday sales Arduino’s Black Friday Sales event offers new and legacy boards at a 20% to 25% discount, as well as a discount for one certification bundle. The number of items on sale is limited, as at the time of writing there were only 11. While the screenshot above shows prices in USD, the Black Friday event is also taking on the EMEA website. Aliexpress SuperDeals Aliexpress will usually organize a “Global Shopping Festival” event for Black Friday with coupons, deals, and lucky draws, but this year the event page is […]

Arduino Opta is a micro PLC for industrial IoT applications

Arduino Opta micro PLC

Arduino has recently announced the Opta micro PLC with industrial IoT capabilities adding yet another solution to the Arduino Pro family. Arduino used to focus on the hobbyist crowd, but with the launch of the Arduino Pro family in 2020 starting with the Portenta H7 board, the company switched its main focus to the more profitable enterprise market. Since then they’ve launched several other boards designed in-house, and last year started collaborating with the introduction of the Arduino WisGate Edge LoRaWAN gateways based on RAKwireless hardware. The Arduino Opta is another one of those collaborations as it was designed together with Finder, who calls their devices PLR (Programmable Logic Relays). Arduino Opta key features and specifications: MCU – STMicroelectronics STM32H747XI microcontroller with 1x Arm Cortex-M7 core up to 480 MHz, 1x Arm Cortex-M4 core up to 240 MHz, 2MB flash, 1MB SRAM (as found in all Portenta H7 boards, and […]

Arduino Lab for MicroPython – An experimental cross-platform MicroPython IDE for Arduino boards

Arduino Lab for MicroPython

Arduino boards have traditionally been programmed with C-like language in the Arduino IDE, but with the Arduino Lab for MicroPython, Arduino added MicroPython to several official Arduino boards. In the words of the Arduino Team, “not an official product yet, an experimental tool”, but I would not be surprised if it becomes an official IDE eventually as the company collaborated with Damien George, the creator of MicroPython, to port the official the virtual machine to a number of Arduino products, and Murilo Polese to develop the Arduino Lab for MicroPython cross-platform IDE for MicroPython.   The IDE looks familiar… Oh yes, I see it now, it’s basically the Arduino IDE, but for MicroPython… 😉  and many of the same features including supporting connection with a board, code upload, file transfer, plus a Python-specific interactive REPL shell. Arduino Lab for MicroPython features so far: MicroPython’s Read Eval Print Loop (REPL) Enter […]

Learn soldering and programming with the Arduino Make Your UNO Kit

Arduino Make Your UNO Kit

Arduino Make Your UNO Kit is a kit with two boards, one for the microcontroller and the other for audio, and all components required that can be used to learn how to solder and then Arduino programming. Once soldering and assembly are complete you’ll hopefully get a working Arduino UNO and an audio synthesizer shield. But before you get there, you’ll need to equip yourself with a soldering iron and some soldering tin to solder the components below to the two PCBs.
