When I am trying to program or prototype stuff I usually do it on breadboards .... but on the another hand it is not practical ... so ... I try to compose my own board with everyting I need ... so some LEDs for example three... red, green, and yellow (on the picture the red one is missing because I do not have it: P) next I use sd card a lot so one sd card slot, 4x buttons, 128x32 pixels OLED screen, one RGB diod (WS2812B), also you can plug an buzzer or potentiometer for meassuring analog value and of course there are some protecting stuff.

I'm a university student and sometimes I "teach" my young colleagues how to code and use electronics, so I need a platform to work with them.
