CORE_STM32 Minimal Parts Setup?

Parts Questions
1

hi,

i have a stm32 board from SmashTV and i´d like to build a small midibox with only 30 buttons and 1 encoder, so only 1 DinX4 module has to be connected.

now, to save myself a little time and to reduce the soldering and the costs i thought, since i don´t need led/lcd/sd-card/… i could leave out some parts. i.e. all the sockets except for J8/9. What about the other parts? i.e. can i leave out the parts for the lcds (ICs, Transistor; Caps; Trimmpots; Resistors; …) ? also, i don´t connect any midi sockets, the core is only going to be accessed via usb, so i won´t be needing any external psu. what can i leave out there? and so no…

Thanks and Greetings

http://ucapps.de/mbhp_core_stm32.html has all the info you need.

I personally wouldn’t leave out the sockets, since well, you never know.

hi nILS, thanks for the reply. i will go through that page and see what i need.

thanks for the tip regarding the sockets, but i´m pretty sure i´m not going to use that core for something else.

Greetings

Quoting the mighty SmashTV, after helping me for an hour straight trying figure out an issue with a freshly assembled core module, where I had left out a few parts that I didn’t “need”:

“See how $0.20 in parts has got you chasing your tail?”

Just sayin’ :ahappy:

alright, :smiley: , i got the point. maybe i just have all the parts ready for assembling just in case…
