Who sells them? I.e I know STM make them, but can you get them through any of the low cost channels, or are they only available though the high cost routes like Digikey and Mouser and selected premium suppliers?
Edit. Digikey want $15 plus carriage $$ for the 103 version
And the 103 only runs at 48Mhz
I think STM missed the boat as I can get. 72Mhz Maple mini for $5 including carriage.
Edit.
sorry I just realised its not 103 it’s a lower spec device, which explains the slow speed.
f4 series version seems only a few dollars more so is better value, but I think the spec on Farmell / element 14 is incorrect as it shows 48mhz for the F4 as well.

To be honest, I think we are not the target group for the nucleo series. The are used in bigger companies and so they can easily try out (same form factor) which chip can be used for their final product. For us it’s not understandable given a few bugs more getting a F4 (or a bigger variant of the F103xx) and buying the smaller one. But if you calculate in industry of 1.000.000+ number of pieces, than there is no sense putting in the 5 cent bigger MCU into the final thing.
BUT, BUT(!)
a maple mini with an onboard st-link v2.1 sounds sexy
They’re of course focused on get design wins in automotive, HVAC, security. Whether these are free, $5 or $15 matters little. The are NOT intended to generate profit unto themselves , but rather, make it easy to learn the ST products and dev. tools.
But they are listed “Key Features” include
extension with Arduino™nano connectivity
The Arduino™ nano connectivity makes it easy to expand the functionality of the STM32 Nucleo open development platform with a choice of specialized shields
But I guess they just mean Arduino shields, and even then I doubt if may shields would work as most of them as designed for 5V logic
I noticed that STM make Arduino shields as well, as we have one poster who was trying to use a STM (3.3V) Bluetooth shield on a Uno and not surprisingly it didn’t work.
I’m not sure STM have a coherent strategy with their “Arduino” compatibility
I’m not sure STM have a coherent strategy with their “Arduino” compatibility
And now running it eclips and cube

Will see how it works but it good to have a debbuger.

It’s my first post and kind of a newbie in the STM32 programing.Just a bit of arduino as well …
I’d like to buy this preaty neat F303K8 or K6 to use it on arduino. It’s got a builtin linker and the board is very tiny !
So,I wonder if someone could provide me the procedure to install the firmware on arduino?
I’m very keen to start with!
Cheers
I started an order and arrived to confirmation without knowing shipping cost. So I aborted.

Just a question. Concerning the F4. Is it still from your work? I got a F411RE sitting on my bench right now. Can’t make it work


Ok I’ll do it.
