Tinkerboy V2.0.01 + Teensy or Pro Micro (pinouts?)

[cobblepot]

I'm doing a (first) build with the following components.

Raspberry Pi Zero W
Gearbest screen, tested on 5V
Tinkerboy 2.0.01 board
Camble's Safe shutdown (pb ed) v1.2
Powerboost 1000c
5v 2000MAH lipo

But I've got a choice to make
Teensy 2.0 USB Dev or Pro Micro clone with ATmega328 are there any advantages to one another or are the practically the same?
Where can I find what button goes to what pin on either board? -edit- realise it doesn't matter, if you keep track what button went were.
But any recommendations anyway?

Another question, is copperwire recommended over aluminium?

I recommend the Pro Micro with the atmega32u4 chip because it's cheaper than the teensy. They're practically the same. I published a post on how to program the Pro Micro with Arduino.

Pinout:


Cyan colors are your regular buttons while the green ones are for analog like the joystick.
