In final yr’s Boards Information, the overarching themes had been shortage and the way distributors and makers coped with ongoing provide chain failures. Some trade specialists even predicted that issues may by no means absolutely return to regular, however fortunately the debacle is easing this yr. As depicted on the quilt, maker titans Arduino and Raspberry Pi are each again with new flagship boards within the type of the Uno R4 and Pi 5 respectively. As I kind this, rpilocator.com is exhibiting pagefuls of in-stock listings for just about the complete Raspberry Pi product vary, and I see lots of of the newest Arduino Uno in inventory at DigiKey, SparkFun, Pimoroni, and our personal Maker Shed. To place it succinctly: boards are again!

Inside this revivified ecosystem, we’re seeing varied thrilling genera evolving. The alphas — or as I’ve been calling them, beast boards — similar to DFRobot’s LattePanda Sigma and Nvidia’s Jetson Orin Nano, supply unimaginable computing energy and efficiency, rivaling and even exceeding their desktop counterparts in some purposes. One other attention-grabbing class of all-in-one hybrids has emerged from the primordial ooze, which function built-in shows, sensors, and typically even cameras. Boards just like the SparkFun Datalogger IoT, M5Stack CoreS3, and DFRobot Unihiker signify a whole venture lab in a single compact unit, permitting you to start out diving into code instantly, with none soldering or breadboarding.

Final yr, we recognized a number of species of silicon that had been thriving in our difficult atmosphere. RP2040, ESP32, and the brand new phylum of RISC-V-based chips proceed to unfold their DNA throughout the dev board ecosystem, at the same time as different chips change into out there as soon as once more. Throughout this yr’s featured boards, we’re nonetheless seeing various Espressif ESP32-based and Raspberry Pi RP2040 designs, in addition to the occasional STMicro, Nordic, Realtek, GigaDevice, NXP, Broadcom, Renesas, and even Intel chip. Whereas Arm nonetheless dominates, RISC-V chips seem like climbing the silicon meals chain. And if you wish to create your personal specimen, providers like Zero to ASIC Course and Tiny Tapeout that allow you to do exactly that!
The Web of Issues (IoT) biome has been evolving quietly, maybe considerably within the shadow of the burgeoning AI habitat, though the tempo has picked up just lately due to the rising recognition and availability of LoRaWAN, enabling merchandise like Seeed’s SenseCAP T1000 LoraWAN Tracker and Wio Tracker 1110. IoT behemoths Particle are again with a brand new Photon 2 Wi-Fi/BLE board and a beneficiant Free tier of their cloud platform that ought to far exceed the wants of most makers. And when you’re actually heading out within the wilderness, the SparkFun Artemis World Tracker can ship and obtain brief messages nearly anyplace by way of the Iridium satellite tv for pc community.
Beast Wars
Whereas single-board computer systems (SBCs) like Raspberry Pi and LattePanda might dwarf the facility of smaller microcontroller boards, there are even mightier megafauna that concentrate on high-performance computing, usually for AI, industrial, and server purposes. In comparison with the quad-core Cortex-A72 processor discovered within the Raspberry Pi 4 for instance, a Jetson Orin module incorporates six to 12 A78 cores. Mixed with the Ampere GPU Tensor and CUDA cores, the six A78 cores within the Jetson Orin Nano Developer Equipment present 80x the AI efficiency of the earlier entry-level Jetson Nano, with 6.6x the CPU efficiency — corresponding to an Intel i7 on compute alone.
However whenever you’re able to unleash the final word beast, the Ampere Altra Dev Equipment’s 128 cores benchmark within the realm of 100 Raspberry Pi 4s, and with larger power effectivity. These machines outdo even Intel’s highly effective Xeon D-2700 with a number of occasions the efficiency at a fraction of the power value, and the power so as to add Nvidia GPUs for much more AI efficiency.

As boards evolve, so do the language households used to speak with them. Adafruit has invested closely in supporting their CircuitPython fork of the MicroPython compiler and interpreter over the previous six years, and with assist for a lot of widespread SAMD-, nRF-, and RP2040-based boards, plus a brand new internet workflow in 8.x that permits ESP32-based boards for use, the world of {hardware} improvement is opening up delightfully to a era of Python software program builders.

In the meantime, Arduino have thrown their weight behind the unique MicroPython platform, each within the type of their very own “experimental” Arduino Lab for MicroPython IDE, and of their assist of the OpenMV IDE. Raspberry Pi have additionally favored MicroPython with their Pico and Pico W boards and documentation, though builders can simply as simply use CircuitPython if they like. UK-based serial innovators Pimoroni have additionally forked MicroPython to assist their very own RP2040-based merchandise, in addition to Raspberry Pi’s Pico boards.
Regardless of Python’s emergence as a good way to get began in embedded, we’re nonetheless seeing C/C++ dominate total, with most distributors taking a C-first method to driver/library improvement and board assist.
As species mature, they have an inclination to evolve specialised variations to deal with particular environments. Firms like Adafruit, SparkFun, and Pimoroni have been cranking out distinctive, special-purpose boards focusing on LED animation, cosplay, residence automation, information logging, and different particular purposes, typically based mostly round cheap RP2040 and ESP32 chips. Pete Warden’s Helpful Sensors has taken this idea even additional, with gadgets that reply a single query like “Is that an individual?” or “What does that QR code say?” Initiatives that after known as for a general-purpose Uno or Feather, plus a stack of shields, breadboards, and breakouts, can now be completed with a single, purpose-built board like Pimoroni’s Servo 2040 18-channel servo controller and Interstate 75 RGB LED matrix driver, Adafruit’s Matrix Portal S3 CircuitPython-powered web show enabler and RP2040 Prop-Maker Feather LED/audio/servo controller, and SparkFun’s Factor Plus Matter MGM240P residence automation nexus.

We Are the Mutants
Over a decade in the past, a curious mutation appeared on the maker panorama. In a world of C and C++, a brand new board emerged based mostly on Microsoft’s C# language and .NET framework. As was the fashion on the time, the board was named Netduino, for its Arduino Uno kind issue. Its creator, Chris Walker, even wrote a Getting Began information for Make: in 2012.
Quick-forward to 2023, and the Netduino, acquired by Wilderness Labs, has developed into the Meadow venture, with the Adafruit-style Meadow F7v2 Feather rising from beta by way of the v1.0 Meadow.OS this yr.
In the identical manner that Micro/CircuitPython allows software program builders to dive into {hardware} improvement, the .NET Customary-compatible runtime permits a military of C# devs to create enterprise-level IoT options.
With an intensive API, improbable documentation and examples, the out there all-in-one Mission Lab v3, plus copious detailed Hackster walk-throughs, Meadow is a good way to get began with embedded improvement for .NET devs — or anybody!
Excitingly, we’re seeing extra general-purpose boards that encourage crossbreeding due to the plethora of Stemma QT, Qwiic, and Grove ports that ease cross-vendor compatibility and obviate the necessity for breadboarding or soldering when just some sensors or actuators are wanted for a venture. Symbiotic relationships between distributors have resulted in some attention-grabbing collaborations as properly, such because the beefy new i.MX RT1010-powered M7 Metro from NXP, Adafruit, and DigiKey, and the thrilling new XRP (Experiential Robotics Platform) package from SparkFun, Raspberry Pi, DigiKey, DEKA, and others, which offers an affordable on-ramp to FIRST Robotics with a free curriculum from Worcester Polytechnic Institute.
The world of boards is flourishing once more, due to renewed provide and elevated variety. It was extremely difficult to slender the side-by-side comparability in our 2024 Boards Information, mailed with this subject, to simply 81 standout boards, and more durable nonetheless to select 14 supreme specimens for our New and Notable record. If one theme has emerged throughout the ecosystem this yr, it’s that there’s by no means been a greater time to be a part of this vibrant, ever-expanding neighborhood.
