Teensy 4.1 commercial product

I know that Arduino have their "Pro" version to be used in industry applications. Do the Teensy 4.1 have some equivalent? I'm in the startup of making a CANbus sensor reader and I really like the Teensy 4.1 but if I need to take over some of the CE responsibility for the MCU I will probably have to not use the Teensy family of products. Anyone that could shed some light?

Found on (as an example) the Portenta H7 Lite page:
The following Declarations of Conformities have been granted for this board:
RCM
CE
FCC
UKCA
REACH

Question: What is “CE”? (Update: I think it’s that European conformance thing?)

The Teensy is great for commercial products. It’s robust and well-designed. I think of it as occupying two possible levels:
1. Providing a design where you build the board with the processor yourself and buy bootloader chips from PJRC.
2. Use the Teensy as a drop-in MCU onto a carrier board where you’ve created the things you need.

As far as providing cases or specific packaging or specific interfacing, I don’t see that as the Teensy’s role.

Paul has done a lot of the engineering and has solved many problems that you’d encounter anyway. (On the other hand, if you’re well-versed in electronics design then this part might not matter as much to you.)

Which brings us to the ecosystem: it’s a very capable project where you can do almost anything, but there needs to be software support. That includes the Arduino ecosystem and framework, but there are others. It’s probably capable, physically of doing everything you need. You will either have to write software yourself or find a library that does it for you. There’s probably at least the starting point for everything, but what you find might need some tweaking.

In any case, the Teensy design/board itself is very capable and, unless you need a very large number of units and you have manufacturing experience behind you, it’s quite a good thing to use.
 
Thank you for the feedback but I think you missunderstand me. The problem with Teensy isn't its capabilities, it's the lack of certificates (CE being one). Look at the list I provided REACH, FCC etc. are important things to have if we (our company) want to use the Teensy board in our commercial product.
 
If you have your own electronics that a module connects into then you need to get CE / FCC certification for your end product.
Since that end product that you are testing includes the teensy it doesn't matter what certifications the teensy has, all that matters is what certifications your end product can pass.
edit - yes the Arduino modules have certificates/DoCs, but as soon as you plug them into any active electronics those become meaningless when it comes to your end products certification. All they do is indicate that it is possible to build a product using them that passes, without the test reports showing the pass margins they don't indicate how easy it is to do that.

The one exception to this is for radio transmitters. Intentional radio transmitters require a lot of additional testing, if you use a module which is pre-certified with modular approval and use it within the conditions stated on that approval then you don't need to do those tests. Instead you put in your documents/ on the sticker that it contains module with FCC ID nnnnnnnn. Edit - this doesn't mean you can skip the whole certification thing, you still need to do the non-radio transmitter testing yourself. All it means is you can skip the extra and expensive intentional transmitter tests.

Since the Teensy doesn't include a radio transmitter this isn't applicable.

For what it's worth we've used Teensy4.1 on commercial products and not had any issues passing all the standard FCC/CE tests.

I do find it professional to comply to the conformities. But when it comes to REACH you do need to provide your ingredients since I cannot guarantee my product conform to REACH if one or more of my used components isn't certified. So, at least REACH is something you probably want to look into.

If this isn't something you intend to do please state so somewhere where it's officially readable.
 
The Teensy 4.1 doesn't have specific industrial certifications like CE, FCC, or others that the Arduino Pro versions do. While it’s powerful for projects like a CANbus sensor reader, for industrial applications, you may need to ensure compliance yourself. Consider consulting with a certification expert if necessary. :)
 
I am not specificaly speaking of Teensies products here.
CE marking is a self-declaration. It doesn't mean the manufacturer really did all the testings. I have seen CE products where the Certificate/Declration and/or the test report only shows emissions tests, and nothing about immunity. And vice versa.

For the EMC part, there are several applicable standards, depending on the application. For industrial devices, applicable standards are EN61000-6-2 for immunity, and EN61000-6-4 for emissions. Tests descriptions are in the EN61000-4-x suite.

As described by AndyA, the certification should apply for the final product.
