I am working on a prototype using existing breakout boards from open source hardware manufacturers (Sparkfun, Adafruit, Teensy etc...). Everything is going great!
I am at the stage where I'd like to start designing my own PCB in order to consolidate the components into a single board.
Right now, each breakout board is powered by the same LiPo battery, so it seems that I might be able to simply use the existing schematics from each board and simply combine them onto a single board, where each "component group" draws its power from the battery and shares the ground... analogous to the manner in which the individual breakout boards are currently wired up.
Is this as simple as it seems, and is it common practice for beginning circuit builders to take this approach without implementing KVL, KCL, and Thevenin node calculations, etc...
Thanks for any advice on this.
