When Qualcomm announced its acquisition of Arduino in October 2025, the tinkerer and maker community watched nervously. Large corporate acquisitions rarely end well for open platforms after all, and enshittification is something that often follows.

And now, what's followed is unsettling. Adafruit Industries, makers of popular development boards and a respected voice in the open hardware space, have sounded the alarm.

According to Adafruit, the new policies introduce sweeping user-license provisions, broaden data collection (particularly around AI usage), and embed long-term account data retention, all while integrating user information into Qualcomm’s broader data ecosystem.

Section 7.1 grants Arduino a perpetual, irrevocable license over anything you upload. Your code, projects, forum posts, and comments all fall under this. This remains in effect even after you delete your account. Arduino retains rights to your content indefinitely.

Damn, I had no idea Qualcomm bought them.

Qualcomm is one of the worst companies. I'm certainly not going to support Arduino anymore.

    This can't be something they can do under the GDPR, right? You have your right to have your data deleted and to be forgotten.

    You have your right to have personally identifying data deleted. My understanding is that most companies let you delete everything because that's the simplest way to comply but they don't have to do it that way, they can just take your name off of everything and anonymize it instead. Like how all your posts remain on Reddit if you delete your account, they're just no longer associated with your old username.

    Arduino has always been a kinda shitified version of Wiring. The “founders” stole it from one of their grad students and have been making kinda dumb decisions since.

    The main thing they’ve been good at is marketing. Arduino is a great name, but stumbling into the oddly positioned headers to make the shields unique is a good example of kinda dumb choices. Also the infighting with the board maker and ex-professors.

    Wiring is a terrible name for a language, and completely unsearchable, but here’s a link to the originators of the wiring language (what became arduino) if you’re interested.

    Geez. Everybody should switch to PlatformIO already. It’s multiple magnitudes better. You can version control your dependencies without hunting down each package. That alone would be worth the switch.

    As for hardware, ESP32 is also a magnitude more powerful, cheaper and smaller than Arduino. They can use the same code.

    Here's the solution. Stop using Arduino. That's how people power work. Then a new open alternative will pop up, and people can start using that. Ones desire to create and build, should never belong to only one brand - but a universal brand - whenever possible.

    i think it was already dead and replaced by the esp32s - the original arduinos are too expensive for what actually offered: get the performance of a 8-bit cpu with 2k RAM but at raspberry pi prices

    Qualcomm has quietly made some massive changes to Arduino's Terms of Service and Privacy Policy, marking a clear departure from the platform's founding principles.

    According to Adafruit, the new policies introduce sweeping user-license provisions, broaden data collection (particularly around AI usage), and embed long-term account data retention, all while integrating user information into Qualcomm’s broader data ecosystem.

    Section 7.1 grants Arduino a perpetual, irrevocable license over anything you upload. Your code, projects, forum posts, and comments all fall under this. This remains in effect even after you delete your account. Arduino retains rights to your content indefinitely.

    The license is also royalty-free and sublicensable. Arduino can use your content however they want, distribute it, modify it, and even sublicense it to others.

    The terms further state that users are not allowed to reverse engineer or attempt to understand how the platform works unless Arduino gives permission. Adafruit argues that this contradicts the values that made Arduino attractive to educators, researchers, and hobbyists.

    The Privacy Policy states Arduino is wholly owned by Qualcomm Technologies, Inc. User data, including from minors, flows to other Qualcomm Group companies.

    Stupid question.

    Does this apply to what you write and upload on the Arduino IDE to your boards? Or just whatever you publish on their website/ cloud?

  • Imo, arduino is also mostly a software project nowadays. While they did make a bunch of avr boards that were quite novel and interesting at the time, now they are not as good in terms of both price and performance compared to various arm-based boards.

    What keeped arduino alive is a bunch of libs and arduino ide cores for various boards ppl have written over time.

    Yes, the 2040 is a microcontroller.

    RP 2040: https://www.seeedstudio.com/XIAO-RP2040-v1-0-p-5026.html

    RP 2350: https://www.seeedstudio.com/Seeed-XIAO-RP2350-p-5944.html

    Nordic Semi nRF52840, Bluetooth only board: https://www.seeedstudio.com/Seeed-XIAO-BLE-nRF52840-p-5201.html

    There are a few others by this manufacturer of different chips, none quite as fast as the ESPs though:

    https://wiki.seeedstudio.com/SeeedStudio_XIAO_Series_Introduction/

    I'm only linking the Seeed ones because they're high quality. They're also the only ones I've found this size with built in battery chargers.

    Hope that helps. Oh and as a bonus, here's someone using the RP2040 and an OLED to turn a lego brick into a Doom machine:

    Are RISCV microcontrollers out yet? Might be a good idea to rally around making a fully open IDE ecosystem and breakout board standard for it (maybe even make it pin compatible with the old school Arduino, surely they can't sue for that right?)

  • source
  • [–] 9 points 11 months ago

    Thankfully, this doesn't seem to apply to code written outside of the Arduino ecosystem, so i ASSUME that if you're writing code for a cloned board using PlatformIO that these new terms don't apply to you

    If that's not the case, I'll switch to micropython (probably easier anyway)

    Raspberry pi was founded as a cheap accessible computer that schools with few resources could afford. $25 boards, or if you had big bucks $35. With the intention the price would stay like that with improving technology. They broke this model with the rpi4 and have only gone up in price.

    There's things like the ESP32, and there's a bunch of RPi MCU based boards. There's actually enough competition that the non-arduino boards are often cheaper while being more powerful.
