I'm taking up a major project for my final year in college through which I plan on learning about the ARM architecture.
I want to build my own custom development board instead of using a pre-designed one. I understand the time and effort this will take and my professors and mentors will help me through this process.
My requirements are:
I need the development board to run be able to run linux OS. I will be programming in C++.
Wi-Fi is a must.
I will also be using voice recognition for voice commands.
I will need to connect a few sensors and actuators.
Low power and long lasting on battery.
An LCD or LED display.
As this is a project, I'm looking for cheaper options. I do not want to use something like an arduino or raspberry pi simply because I want to have this learning experience.
I'm a complete beginner in ARM architecture and honestly do not know where to start. I've programmed on an Atmel architecture in the past(on a pre-designed development board) as well as arduino.
