Need component advice/help for a instructable Answered

I wanted to build this instructable, but it requires STM32F051 micro controller. However there's different types of 'STM32F051' micro controllers such as a T8, K8, C8, R8, V8, K6 C6, R6, etc.

So does it matter which kind variant i use or will they all work the same?
If it does matter, what kind do i use? Or is there an alternate micro controller that will work?

As always: Read The F... Manual. Or data sheet in this case.

As on page 115 of this data sheet:

Example

:STM32F051 R 8 T6x

Device family
STM32 = ARM-based 32-bit microcontroller

Product type
F = General-purpose

Sub-family
051 = STM32F051xx

Pin count
K = 32 pins
T = 36 pins
C = 48 pins
R = 64 pins

User code memory size
4 = 16 Kbyte
6 = 32 Kbyte
8 = 64 Kbyte

Package
H = UFBGA
T = LQFP
U = UFQFPN
Y = WLCSP

The memory size depends on the application inside, check the program / hey file. The pin count and package has to match the board. Check schematic and board layout.

BTW: None of those available packages are easy to handle for beginners.Are you sure, you are up to the task soldering them?

I understand however i am extremely new to electronics and electrical engineering of any sort so i dont know what the pins and package mean. I know about memory normally but not when it comes to circuits, so for the most part it wouldnt really help me to read the data sheet when i dont know what it all means.

And now that youve explained all of that, i am starting to consider postponing the project for a later date.

Thanks for the help by the way.

You might want to start with some more basic projects to get going...
Pins= input and output - a huge number of sensors, extras and such need more pins than a lew LED's controlled by two switches.
Package is the form factor, e.g. to be soldered by sufarce mounting, balls or as a simple dip package.
If in doubt use Google / Wikipedia to read up what is unlcear to you.

Check the datasheet or the chart here.
I would say it is a matter of available pins, so check how many you need and go for the one with enough ;)
But usually the best place to ask is in the comment section of an Instructable or by sending a PM to the author is no reply within a week or so.
Did you try that already (I did not check)?
