Didn't really mean that sort of "embedded" - just good old boxes doing what they've always done. However Ards are not going to go away anytime soon, they have a good solid niche and loads of support/docs. Still good for a lot of (esp low-power) projects and for students. Too much of the "newer/better" chips/boards in that rough category are very complex, operating systems even, and burn power like mad. I remember the PIC16(c/jw/f)84 chips fondly - and did lots of useful things with them. Programming almost entirely in ASM. Incredibly versatile if you read the docs. When I think "embedded" that's what I tend to think of first, my 'reference'. Came to love the 12fxxx chips too - if you didn't need super speed they were easier, cheaper, more versatile, than the old 4xxx/7xxx logic chips.

Ard offers (offered ?) a 'dual processor' model. I think the hotter CPU would run a very basic Linux. The two CPUs could, kind of awkwardly, talk to each other. But I'm not sure this is the way to go for Ards. Different universes. If you need a PI then you go with a PI. If you need really simple stuff then you go with an Uno or 2560. There is a corp that still sells "RuggedDurino", all the I/O pins have voltage clamps. Kind of intended for students who tend to fuck things up they'd also be just great for more "industrial" apps where voltage spikes might happen.

The Q has a Cortex-A and a Cortex-M and is much less expensive. The Portenta H7 has a STM32H747 https://www.st.com/en/microcontrollers-microprocessors/stm32h747-757.html That's an odd duck, two cores but one is a Cortex-M7 and the other is a Cortex-M4. No Cortex-A MPU, only the two MCUs. It uses the Arm Mbed RTOS that Arm dropped. The Q uses Zephyr for the MCU. The old Atmel UNOs will be around for a long time but even the UNO R4 went to a Cortex-M4.

Like 99.99% of all the brushless motors made, are made in China. The stuff that goes into drones is being sold off at rock bottom prices on ali-express. China outcompetes and undercuts the market in neodymium magnets and lithium batteries. I can buy RP2040 based devices made in china cheaper than I can buy them in the UK. All sanctions are leaky. When I was in a South Africa under sanction my bosses brother filled a teddy bear with semiconductors and sent it as a christmas gift. Amazing how much you can stuff in a big German teddy bear. It's not too hard to stop a majority of - say - oil exports from Russia. Its a damn sight harder to stop a tonne of RP2040 chips in the back of a Toyota pickup wrapped in am Iranian carpet being driven up to Moscow. The software in those drones will be made by 100% US based toolchains. Russia has very little by way of native hi tech industry at all, and less every day, thanks to Ukraine and Europe's ability to generate long range precisions fires that can outfly jamming and still hit their targets. It's a globalised world. Live with it. Russia thought they could go it alone. They were wrong. -- “A leader is best When people barely know he exists.

A Pico would be a > better starting point for new projects. Don't write off Arduinos quite yet; Qualcomm just announced the acquisition of Arduino. It must have been it the works for a while since Arduino is shipping the UNO Q at the end of the month. It has a Qualcomm Dragonwing MPU and a ST STM32 MCU. The top side is physically compatible with the UNO and the bottom side has additional connects. https://www.arduino.cc/product-uno-q The Dragonwing runs Debian rather than the Debian derived Raspberry Pi OS. The initial offering has 2GB of RAM but it will be followed by a 4GB version. It's an interesting design. The RPi 5 is a Cortex-A76 and brings out the GPIO lines almost as an afterthought, often with a Pico hung off the side for real time processing. The Dragonwing is a quad-core Cortex-A53 with the builtin ST with a Cortex-M33. The MCU has Arduino Core running on the Zephyr RTOS. That seems to be the way to go since Arm phased out their RTOS. There's a new IDE too, although the current Arduino IDE will work too. That will make life a lot easier. STM parts are used in a lot of realtime systems but configuring the IDE is an arcane process as is their C++ SDK.

Back around 2010 many modellers were flying autonomous aircraft using Arduinos and public domain code. But that chip is available direct from the far east. I don't know how one would stop them being bought by intermediaries and shipped off to Moscow. -- "It was a lot more fun being 20 in the 70's that it is being 70 in the 20's" Joew Walsh
