I want to create a prototype using a RaspberryPi model B+. I created a list of the things I think that I'm going to need.
I need the following modules connected to an RPi:
1. a camera
2. a thermal printer
3. a display
4. a button
5. an EU power adapter (5V)
1. The camera
I am going to use the standard RPi camera probably. I need the camera as a bar-code scanner.
2. The thermal printer
I would like to use this thermal printer or the PiPsta. The PiPsta is expensive but on the positive note comes with a USB input, so I don't have to mess with GPIOs and (probably) soldering.
Any advise here would be nice.
3. The display
First I was about to settle for a monochrome display. Then I found the ePaper display which is very good looking although way more expensive.
4. A button
I need a to initiate the procedure. A button with some LED would be nice.
My questions are:
Can all these devices connect to a single raspberry pi board, or do I need some sort of extension?
What else do I need to get all these things attached to the RPi?
Please feel free to share any design tips.
