The Consumer Electronics Show in Las Vegas is traditionally where the big names in tech show off their upcoming products, and the 2020 show was no different. There were new smartphones, TVs, and home automation devices from all the usual suspects. Even a few electric vehicles snuck in there. But mixed in among flashy presentations from the electronics giants was a considerably more restrained announcement from a company near and dear to the readers of Hackaday: Arduino is going pro.

While Arduino has been focused on the DIY and educational market since their inception, the newly unveiled Portenta H7 is designed for professional users who want to rapidly develop robust hardware suitable for industrial applications. With built-in wireless hardware and the ability to run Python and JavaScript out of the box, the powerful dual-core board comes with a similarly professional price tag; currently for preorder at $99 USD a pop, the Portenta is priced well outside of the company’s traditional DIY and educational markets. With increased competition from other low-cost microcontrollers, it seems that Arduino is looking to expand out of its comfort zone and find new revenue streams.

That’s a Lot of Pins

The Portenta H7 is obviously a far cry from the relatively dinky 8-bit Arduinos that we’ve all got filling up our parts drawers. Developed for high performance edge computing applications, the new board is powered by a 32-bit STM32H747XI that utilizes both an ARM Cortex M7 and an M4 running at 480 MHz and 240 MHz respectively. The two cores can work independently, allowing for example one core to run interpreted Python while the other runs code compiled in the Arduino IDE. When they need to work together, the cores can communicate with each other via a Remote Procedure Call (RPC) mechanism.

The new 80-pin connectors on the Portenta

Outwardly, the new board doesn’t look far removed from the modern Arduino form factor we’re used to. The USB connector has been upgraded to a Type-C, but the Portenta still retains the dual rows of pads ready for hand-soldered headers — that’s their more recent pinout that they call the Arduino MKR form factor.

If you look on the back of the board however, you’ll see that they’ve added two 80-pin high density connectors. According to the product page, these are intended to allow the Portenta to simply be plugged into a device as a removable module. The idea being that devices in the field can easily have their Portenta swapped out for an upgraded model. Some digging into the product page documentation section turns up a schematic that lists the connectors as Hirose DF40C-80DP-0.4V(51).

The base model Portenta features 8 MB SDRAM and 16 MB NOR flash, but it can be custom ordered with up to 64 MB of memory and 128 MB of flash should you need it. It’s also possible to delete various interfaces from the board when ordering, so if you don’t want network connectivity or the NXP SE050C2 crypto chip, they can simply be left off. However as of this writing it is unclear as to what minimum order quantity is necessary to unlock this level of customization, or or how much these modifications will change the unit cost.

Year of the Arduino Desktop?

The Portenta Carrier Board

The Portenta H7 is an impressive enough piece of hardware on its own, but when it’s plugged into the optional Carrier Board, things really start to get interesting. The Carrier Board provides full size connectors for all of the onboard peripherals, and according to documentation, turns the Portenta into an eNUC-class embedded computer. There’s even support for DisplayPort to connect a monitor, and miniPCI for expansion cards.

With a fully loaded Portenta H7 slotted into the Carrier Board, it would seem you have the makings of a low-power ARM “desktop” computer. Albeit one that wouldn’t outperform the Raspberry Pi Zero, and which costs several times more.

The Arduino press release and product page doesn’t make any mention of what kind of software or operating system said computer would run, so presumably that’s left as an exercise for the customer. While not particularly well suited to it, the ARM Cortex-M family of processors is capable of running the Linux kernel, so spinning up a “real” OS image for it should be possible. Of course with a maximum of just 64 MB of RAM, you’ll want to keep your performance expectations fairly low.

Where Does Portenta Fit?

We can’t even speculate what a maxed out Portenta would cost, and there’s no pricing or release date for the Carrier Board. But even at $99, the base model Portenta H7 would be a tough sell for hackers and makers who are used to buying dual-core ESP32 boards at 1/10 of the price, or the Teensy 4.0 which has a 600 MHz Cortex-M7 at 1/4 of the price. Which is fine, since this board isn’t intended for the traditional core Arduino audience.

Seeing the carrier board, we can’t help but notice some parallels here with the Raspberry Pi Compute Module. With connections broken out to a SODIMM header, the idea of the Computer Module was to help bridge the gap between the DIY community and the commercial one by offering up a Raspberry Pi in a more rugged form factor that would be easier to integrate into end-user products. But since it wasn’t any cheaper than the stock Pi, there wasn’t a whole lot of incentive to switch over. We haven’t seen consumer products advertising “Raspberry Pi Inside!” so it’s hard to tell if there has been any meaningful adoption from industry.

One has to wonder why any company that has the resources to integrate such an expensive board into their products wouldn’t just come up with their own custom design around the Portenta’s STM32H747XI chip, which even in single quantities, can currently be had for less than $15. The difference may end up coming down to the world-renowned community that surrounds the Arduino brand, and the company’s efforts to modernize their toolchain.

Love it or hate it, for many people embedded systems means Arduino. Now Arduino is leveraging its more powerful MKR boards and introducing a cloud service, the Arduino IoT Cloud. The goal is to make it simple for Arduino programs to record data and control actions from the cloud.

The program is in beta and features a variety of both human and machine interaction styles. At the simple end, you can assemble a dashboard of controls and have the IoT Cloud generate your code and download it to your Arduino itself with no user programming required. More advanced users can use HTTP REST, MQTT, Javascript, Websockets, or a suite of command line tools.

The system relies on “things” like temperature sensors, LEDs, and servos. With all the focus on security now, it isn’t surprising that the system supports X.509 authentication and TLS security for traffic in both directions.

Honestly, we tried it and the web-based IDE couldn’t find our MKR1000 board under Linux. That could be a misconfiguration on our part, but it is frustrating how little information you get from many web-based tools. It decided we had multiple Arduinos connected (we didn’t). Then removing a multiport serial adapter made it see no Arduinos even though there was an MKR1000 Vidor attached.

Naturally, there are plenty of options when it comes to putting devices on the cloud. However, if you are only using Arduino boards, this one is going to be pretty seamless — assuming it works for you.

In this video, our friends at PubNub are going to create a smart home network that builds upon their previous Johnny Five tutorial. They again hack an Arduino Uno using JavaScript, but this time to create the simplest smart bulb. Because by “smart bulb,” we really just mean an LED.

The tutorial was developed by Tomomi Imura from PubNub and also uses Johnny-Five. No, not the robot from the movie Short Circuit. It is an open-source JavaScript robotics framework that lets you program an Arduino with Node.js. The bulb itself is remotely controlled via a web portal.

To establish the realtime communication between the Arduino and a web browser, the PubNub Data Stream Network (DSN) is used. PubNub provides global infrastructure and allows you to build and scale real-time apps and IoT devices quite easily.

The remote controller (web app) is written in JavaScript. This is a simple user interface that includes only one button. While a completed code sample is available on CodePen, this tutorial employs a simplified version so that it’s easier to follow along.

 

Interested in the world of hardware hacking, but feeling left out because you just don’t have the time to learn another language? Or maybe you aren’t comfortable using Sketch to program? Have no fear, you can easily use JavaScript to program boards like Arduino and Genuino. Yes, just JavaScript!

In this series of video, PubNub’s Tomomi Imura shows you how to start hacking an Arduino with Node.js using Johnny-Five, a JavaScript Robotics Framework.

Part one of this tutorial covers:

  1. Setting up a board.
  2. Building the Hello World of hardware, a LED blink.
  3. Writing your Johnny-Five code to make it blink programmatically.

Enjoy the tutorial!

Breakout – [via]

Breakout is a prototyping tool for exploring the intersection of the web and the physical world. The popularArduino platform and the Firmata protocol are leveraged to enable users to access physical input and output purely from javascript. This makes it easy for anyone familiar with javascript and basic web development to explore the possibilities of using physical I/O in their web applications. Furthermore, the Breakout framework includes a growing library of hardware abstractions such as buttons, leds, servo motors, accelerometers, gyros, etc enabling the user to easily interface with a range of sensors and actuators using just a few lines of javascript code.

Breakout grew out of a need for a simple platform to enable designers to prototype functional web-based interfaces to the physical world. It is based largely on the Funnel toolkit and informed by the experiences of the developers of both Funnel and Breakout as designers, technologists and educators.
