So, I’m interested in putting a bunch of different modules together on a single pcb that I can swap into my model trains. I’ve already attempted putting every module together manually, but there is just way too much wiring and unecessary crap to fit easily into an O gauge locomotive. I’ve managed to short quite a few things already.
This is the list of things I’d like to get onto a roughly 4"x2" board:
1: Max9744 amplifier - similar to this Overview | Adafruit 20W Stereo Audio Amplifier - MAX9744 | Adafruit Learning System without all of the unecessary ports and connectors.
2: NRF24l01 pa lna + 3.3v converter (so I can supply the board with 5V and not have to worry about another external converter)
3: Slots for a teensy 3.2 or LC to be mounted
4: SD card reader
5: Motor controller (can handle 13A 12Vdc) currently using cytron MD10C, but a basic H-bridge design would probably be fine, so this might be one of the easier things to put on the board
6. At least 3 mosfets for the control of a fan, smoke unit heating element, and smoke fluid pump
So, my main questions are:
- Is this even remotely possible, in your experience?
- What is a good software to use in designing such a board, with the easiest learning curve? (only one I even know of is OrCad, could probably get a copy through school).
- Are there companies out there who would put something like this together, or would I have to just print the pcb and solder all of the elements on myself?
Thank you guys, and of course any advice is appreciated. Just looking for a good place to start, I know there is a lot of information out there on the internet but its quite overwhelming… it would be nice to hear from someone who has had experience with this kind of thing.
