I have the aluminium version (the cheap one).
It works very nice

No need to buy the expensive one.

The cheap one is fine - several people have them (I have one)

The other type that is also OK is this type (but some don't include the wires)

They are not complicated devices, they just have an STM32F1 device on them, and a voltage regulator.

You can do it either way, if hosted on this site, you may wish to resize images if "inline" is utilized and then attach higher resolutions if there is value to be gained by inspecting the details - zip 'em if you do not wish the server to render them (not everyone has unlimited bandwidth).

I don't think that anybody in this forum AND with M4 boards own one. But that does not say that it wont working (with a lot of work).
I would read the whole F4xx section here and before read this:
viewtopic.php?f=39&t=118
I have 3 or so different STM32F415 boards. Lots of Flash, RAM, speed and FPU.
I like the repertoire of boards for ST from waveshare.com. I've ordered and gotten fast delivery, professional treatment.

I have several of the Mikroe Mini-M4 boards with that CPU, and they connect easily to the ST-Link v2 for SWD flashing and debugging. I erase the Mikroe bootloader but you could keep it - it takes any .HEX (Intel format) from any compiler/linker. Or you can flash a different one. The in-ROM DFU loader is in the chip but the jumper to enable it is hard to get to. So I just use ST-Link to flash.
And ST-Link enables "real" debugging using IAR, Keil, Eclipse or VisualGDB.

I don't use Arduino on the ARM. there are several "wiring" emulators for the ST. But really, using CubeMX + ST's HAL is 1000% better.

enclosed... photo of quick wiring of ST-Link to Mikroe STM32F415 board. This setup also uses a USB/Serial (3.3V) to serial port 1 on this board.
Again, I don't use Mikroe's compilers.

Personally, I find that the use of the professional tools is easier to a large degree for serious programmers. For weekend programmers, likely the Arduino platform is a better option. There is a lots of expertise in the forum but the name "stm32duino.com" was selected to migrate from Arduino.cc to a forum with a concentration on the STM32F103 re-hashed port of the Maple core for Arduino pre-version 1.0, I think 0022 or such.

Anyway, all of the above ties into the dialog in this thread:
viewtopic.php?f=46&t=499

A lots is coming quickly at the forum, I suspect Roger will need some time to absorb it all as he is extremely busy at this time.

From my understanding the F415 only differ from the F405 by having an additional crypto/hash coprocessor.
So, since the F405 is already working fine (STM32F4Stamp and Netduino 2 Plus), I don't see any reason why the F415 won't work.

Hello folks, new user here.
I've been coding on Arduino and Teensey, I'm studying C++ so you can guess why I'm posting in this thread: hunger for boards :D

First I got myself a few weeks ago a generic board: http://www.aliexpress.com/item/STM32F10 ... 85935.html, impulse buy , that's after a first glance of http://www.rogerclark.net/stm32f103-and ... 1-5-x-ide/ that gives me some hope that a noob could put the board to work.

Then after some reading I was on my way to get myself a ST Nucleo board and a TI LaunchPad, but now I'm not so sure about that.
I'm going for a "safe" maple clone like http://www.aliexpress.com/item/leaflabs ... eb201560_9 for a secure takeoff and throw that money into something unbranded like:
- Full board: http://www.aliexpress.com/item/FREE-SHI ... 80157.html
- Small / Light: http://www.aliexpress.com/item/Small-sy ... 42742.html

That with a cheap ST-Link v2 adapter like: http://www.aliexpress.com/item/mini-ST- ... eb201560_9, I have FTDI already.

What do you think about? Are those boards well supported? Maybe there's something more interesting for a noob?
I'd like something well supported, some debugging (I work only on Linux, vim, eclipse, sublimetext) would be interesting for a change, I could use something full-size-optiona for desktop dev and something small - light - low power to take the place of an Arduino Mini-Pro / Teensey, so small and cheap. I'd also like to be able to run Mbed and some *RTOS.

Congrats for the nice site, thanks for all the work done!

Maple mini is your best board to start with

The Blue board (aka BluePill)
This sometimes works, but they seem to vary a bit in their design, and its impossible to tell from the picture.
Some have a 10k pullup on the USB DP line, which is too high to allow the USB bus to be reset by the bootloader

So. Not the best board, but it may work.


Larger boards
I have the "Light" one
http://www.aliexpress.com/item/Small-sy ... 42742.html

but the manufacuring quality was not good, and the reset button and some other things didnt work.

I think I did eventually get it working and installed the bootloader etc, but I'd not recommend it

I can't comment on the other large board. Someone else may have one of these and may be able to comment

Re: STlink

I have one like that, and it works fine !

Let say that I've been disapointed with mMbed under LPC1768, and that I've redesign my board with an STM32F405.
I'm still waiting for the PCBs, but in the meantime, I've used my STM32F4Stamp board to start migrating my software.
I'm now using Arduino_STM32 core along with the FreeRTOS821 in our repro since several weeks.
I'm glad to leaving mMbed framework, where I posted so many question, but also few bug fixes and never got feedback from that community.
(I think it is dying slowly ...)

Have an happy experience here with us !

Thanks Roger, a MapleMini clone is on my way.

I'm giving a second look at those ST Nucleo board as they are available in just 2 days, Mbed compatible.
I see that on the first page of this thread the recommended model is Nucleo-F103RB [1] , yet something like the NUCLEO-F401RE [2] seems more powerful, heck the NUCLEO-F411RE [3] is even better.

So is the F103 - Cortex®-M3 more compatible / stable with STM32duino or should we go with some of those F4* boards?
