The SparkFun folks are cool. Back when I was a broke college student, they sent me free electronics kits. I massively respect them for that.
I'm surprised AdaFruit did something wrong here. They frequently blog about their stances on issues and seem to try to take the moral high ground on a lot of issues.
Next we'll see Waveshare and Seeed Studios have a go? Strange happenings.
I'm guessing to get ahead of any sort of speculation on why Sparkfun stops carrying their products? Perhaps also to get ahead of Adafruit publishing a similar public statement with more/conflicting details?
This aspect is not very surprising, it is usually moral high grounders who end up found to be doing something wrong, people like to compensate and try to put down others when they know they are in the wrong.
You don't actually know that for a fact.
I will say adafruit have clearly been heading in a bit of the wrong direction lately. See the misleading noise about arduino, for example. Have to wonder if the whole tariff situation is hurting them and it is causing these ripples.

I can't help but wonder who decided that, in an electronics forum of all places, *any* form of joke should be unacceptable, but sexual images are only a problem if they are gratuitous or off-topic!
So it's offensive comments, offensive insults, offensive jokes, etc, as I read it, with ; breaking the association.

> Inappropriately involving a SparkFun customer with a private matter
Well those are fun accusations. Looking forward to adafruit response. Anyone has any context?
Keep in mind adafruit and sparkfun are business competitors. Not saying either is lying but statements need to be examined carefully. For what it's worth I've purchased from both many times and was always happy customer so this is sad to see.

> this is not a one-off. nate (the founder of sparkfun) has done this before. anyone who has worked with him long enough knows this is how conflict is handled: deflect, escalate, and try to punish rather than deal with the underlying conduct.
My guess is someone was trying to hit on someone and got mad when they were rejected.

The fact that they mention a "private matter" makes me think this is some petty personal grievance that has somehow escalated to this.
Is there any duty to publish anything? They could release nothing, or nothing with any details, if they have some obligation.
It would have been far better had they not published anything at this point.
The statement that is published places blame, if not accusations of criminal behaviour, on their business partner.
IOW, they already overshared with the intent of damaging the reputation of their business partner.
In my mind, they are already behind; had they released the standard business line "Our relationship with $X has come to an end; we apologise for any inconvenience caused" I wouldn't be so quick to judge them.
But, now I *am judging them, because they clearly felt personally aggrieved by what happened, enough to imply the worst without actually coming out and saying what happened.
I agree in principle, but is there an actual right to privacy in this instance?
I'm asking this in the legal sense, not a moral sense.
They already have.
I don't think that level of detail would be a privacy violation legally and imo not morally either
Public notices for the consumer should serve the consumer. I.e. they should only relate to matters that directly concern them, such as notice of availability, warranty, support or the fulfilment of other consumers' rights. Those statements should be unambiguous and not allude to blame or personal tiffs.
While Sparkfun's statement touches on availability it merely does so as a vehicle for grandstanding and retaliation through gossip and drama. The fact that SparkFun notes it's a "private matter" yet chose to involve the public also makes SparkFun look unprofessional, even if they are the 0% at fault for the circumstances.
Consumers put their trust in a company, it is disrespectful of that trust when trying to embroil them in personal affairs, they never agreed to that.
i’ll stop back and answer anything (sparkfun will not?).
sparkfun is the exclusive maker and distributor of the closed-source teensy and informed us we will not be able to purchase the teensy. this happened after i sent an email reporting the founder, nate, for multiple harassing actions directed at limor, including behavior by him and a former employee.
instead of addressing that, they decided to kill the messenger, me, and also cut us off from teensy.
so! instead of posting weirdo "code of conduct" letters, we are doing an open-source alternative. so customers are not stranded, and this is not a supply chain emergency for us. looking forward to seeing which one delights customers more.
as much as nate wants to continue trying to damage limor’s business and adafruit by scraping our site, and now potentially not paying royalties owed after more than a decade of consistent payments, that’s nothing new. it’s a business strategy to cut others out, not a mystery or a “private drama.”
this is exactly why we do open source. when a closed product or exclusive channel is used as leverage, the correct response is to remove the leverage.
sparkfun chose to publish a vague public accusation. once you do that, speculation is inevitable.
ask away!
Don't worry, he always writes like this, who knows why he thinks he needs to make up excuses, but it surely paints a picture.
I have long noticed high profile people going to court with some kind of cast on, though.
Definitely avoid ad hominems, and focus purely on facts. Provide what information/evidence you can without violating agreements, but only if it's relevant to the situation and includes as much context as possible.
I think what's currently been said is sufficient. You need to make a grown up version of the statement "None of that is true", but yes probably best to leave it at that.
Honestly, this being Adafruit, my default assumption is to believe them. Especially with this super vague "please read between the lines because if I actually say something false it'll be libel" accusation.
Thanks for speaking up.
"Someone did a CoC violation" is just a way for an org to say "someone was an asshole to such an extent it was driving other people away or getting us into legal trouble", with the manner of assholery defined in the CoC. 9/10 times it is nothing sinister.
Of course right now we just don't know what happened.
Unless you have an infinitely wise and patient dictator who can just say "you're an asshole, you go" and always make the right call or something.
This seems very much like two businesses experiencing friction and separating, which happens all the time. You coming in and framing the flames makes doesn't scan particularly positively to me.
Is there any thought to expanding the Freensy lineup beyond a pure clone?
I have zero skin in this game, and personally think the right move is for Adafruit to simply say, "We wish Sparkfun the best of luck" and move on, but the post you are responding to is clearly looking for a public fight.
This would mean admitting the allegations are 100% true and harming their business even more with the risk of losing it all in worst case. Now we can assume it's not as simple as SparkFun makes it. It's a dirty situation, but necessary, and justified if they are really a victim.
> but the post you are responding to is clearly looking for a public fight.
SparkFun started the war, AdaFruit seem to only defend here.
[0] https://forum.pjrc.com/index.php?threads/open-source-teensy-...
one corporate side overshares by pointing fingers and accusing a different corporation...
so that corporation decides to be the better person, declare the opponent as weirdos, then proceed to point fingers at individuals instead for collective action from the public.
nice look, both groups.
I know SparkFun recently took over Paul Stoffregen and Robin Coon's Teensy production (I reached out at the time and Paul said it was cool).
I'm guessing Adafruit got a special deal in purchasing Teensy's from SparkFun but because of an allegation made by you against Nate, they are responding by dropping your entire product line?
Anyway, good luck to everyone involved. It's a small community of companies that provide for makers.
Those seem extremely vague, but I didn't see them mentioned in the blog post.
Anyhoo, sorry we can’t just stick to the technical drama.
Historical garbage and different manufacturing technologies. Be happy if you can get away with only 5V and 3V3 rails in your project. 24V is usually to interface with industrial sensors. And sometimes you see 12V as well, for stuff that's RS232 based.
And on top of that you got a fifth standard, 4..20 mA current loops. That one is used for long range transmission of analog values of a single sensor per wire pair, with 4-20 mA being seen as the value (4 mA = 0%, 20 mA = 100%), and anything less being seen as a cable break, anything higher as a short circuit somewhere.
Lower voltages help with power savings. Higher voltages can and do work better in high power, high noise environments though! 24V as you see is still very popular and useful inany applications.
maybe someone from sparkfun could post advice for you here too...
Fwiw, I’m team adafruit on this. Hope it works out for y’all
In my book, what makes a Teensy a Teensy is 1) hardware support, like 600Mhz clock, CAN, FPU, RTC, other hardware peripherals which the RP2350 lacks and 2) software compatibility with Paul Stoffregen's well documented Teensyduino libraries. I would not buy something else if I needed these features.
Do you plan to do a port? Why not build around the same IMXRT1062? Are you barred from buying Paul's bootloader chips [1]?
[0] https://forum.pjrc.com/index.php?threads/open-source-teensy-...
as for the bootloader chip: we don't want to trade one closed-single-source component for another. if we're going to make something it should be fully open source as much as we can!
finally, for teensyduino libraries that you love: there's no reason they cant be ported (we did an audio port for the samd51) - which specific library are you referring to?
Edit: I see you're comparing it to the 3.2 but I suspect most folks are going to be comparing your offering to the 4.x.
either way, more hardware is better and we don't want to just give people the same-old-same-old... as we mentioned there's lots of things that we can add to make the board useful to people: SWD, USB C, Lipoly batt, onboard storage, neopixel LED, etc). what peripheral/library are you specifically concerned about?
Drama and whatnot aside I'm not really sure why anyone would buy the (considerably more expensive) Teensy over something RP based if RP was suitable for their needs already.
Interestingly despite being a Teensy fan I have found myself reaching more towards the RP when I can because I can't stand the Arduino API and much prefer the RP SDK. I do use Teensy without Teensyduino (Makefile based) and also a bit of the CMSIS-DSP stuff directly - but it's kinda clunky IMO.
I've been working on an audio project recently, and the the ease of use and feature set that TeensyAudio has is incredible.
Teensy 4 does currently fill a pretty unique niche in terms of processing power though. There isn't much like it outside of professional eval boards.
I really hope this doesn’t lead to “boycott” of Teensy per se. I completely sympathize with tensions running high but please reconsider for the good of the community.
https://forum.pjrc.com/index.php?threads/sparkfun-to-manufac...
A lot of those come with very good support and communities as well.
All of that plus maintaining inventory nearer their customers, doing effective QC on units they ship, writing good docs, etc. means you’re getting something a lot more like a “big OEM” experience from the hardware vendor, even if you’re ordering a handful of parts.
The generic AliExpress vendors, in my experience, do not do most of those things. They all support Arduino and/or PlatformIO, and sometimes a “native” SDK like mbed, but you’re often on your own figuring out how to integrate that bare MCU with other devices you need for a complete solution. Docs are often incomplete or untranslated, and it can be hard to know exactly which chip (or associated components like onboard sensors and BME) is on there. It can change between board revisions, or even identically-named parts from different vendors.
There are other players like M5 and RAK who make nice modular platform as well, but their prices tend to be up there with AF and SF.
If you’re not doing business with someone anymore, just drop their products. You don’t owe folks an explanation other than “unfortunately we do not carry that product anymore.”

we do not respond to bullying by backing down. we never have. that is why we are here.
I would have privately let them know we arent going to supply them anymore and wish them the best. That's it.
Public drama is DISGUSTING!
It's sad to see two good companies go at it, but I do like the reminder that they are run by actual humans with emotions. This is why we support independent businesses instead of corporations that act like they are run by robots, and likely will be run by robots soon.

Honestly the whole thing seems like everyone overreacting on both sides. Accusing someone is "doxing" because they used your first name?

Does anyone have an example of one of these "hate sites" that Sparkfun employees allegedly created? That sounds curious.

However, I do wonder what this will mean for Adafruit product availability in Europe, as most stores I know of that sell Adafruit products here are Sparkfun distributors.
reactordev•1h ago
- This blows up in Sparkfun’s face and they lose sales for not having Adafruit so they invite them back. Or Adafruit apologies and comes back.
- Adafruit is forced to become their own distributor and be a Sparkfun.
- Adafruit finds another distributor willing to go to battle with Sparkfun.
- Adafruit is no longer available in Europe.
