/diy/ - Do It Yourself

ohayou /mcg/, I asked on /g/ and got some useful info, but I'm still not certain so I'll ask again here. I want to make a Linux e-reader similar to https://github.com/joeycastillo/The-Open-Book but more powerful. What I've learned from /g/ is that a good method for someone who's never done PCB design is to do prototyping for the software (e-ink screen driver, etc...) on a dev board then copying the design of the dev board as closely as possible for the PCB sketch.
So with that info and a little research I figured I'd buy the pocketbeagle, the e-ink display and start writing an i2c framebuffer driver for it. Does the pocketbeagle seem like a good choice for my application? Is this a good way to get started?
