Development board recommendation

[Jonathan101]

Hi,

New member of this forum!

Can you suggest me a stm32 development board? [Or any other for that matter]

My needs:
I prefer it to contain some leds, button and pmods. I am not interested it to be
compatible or related to Arduino whatsoever.
Price should be: 10$ - 40$

My bg:
I am an embedded engineer, and I work on daily basis with Xilinx products, SOCs
mainly (FPGA & cpu). I writes mainly in c, cpp, python and verilog occasionaly.

My main motive now is to learn the aspects of the cpu: startup program, assembly code, real time application,
without the need to deal with the FPGA part.

I came accross this board:

But I saw it is compatible with Arduino shield, so I struggle to understand if it is
the best fit for me (Or just overkill).

Thanks!

Hi,

I thought of a Nucleoboard, too.
But since you wrote LEDs (plural) and buttons and pmod ...
I discarded it. There is only a single LED, only a single button .. and I don´t think PMOD at all.

This all is listed in the datasheet (I assume you did read it) .. so I wonder why you have chosen it, since it does not even fit your minimal needs.

But I saw it is compatible with Arduino shield, so I struggle to understand if it is
the best fit for me (Or just overkill).

I don´t see why "Arduino compatibiltiy" should be any drawback.

What makes it compatible? The USB interface and a couple of lines to generate RESET and BOOT signal. Is there anything else?

--> Please tell why you think you don´t want it.
If I´m not mistaken this all is on the part of PCB you can break off.

Especially for testing I find it useful to have an (debug) interface to a PC. Also download compatibilty via USB (Arduino or non_Arduino) is more useful than an problem.

There are several providers of development boards. It may depend on your region whether they are available or not.

Thus I´d just do searchon on
* ebay
* your electronics distributor
* other reliable sources
..for according development boards.
