Otti DIY+ XXL version

This is a remix of OTTO DIY+ that is bigger than original and allows you to fit 8x8 LED matrix and 4xAA batteries.
The matrix I use is in the pictures and for it to fit it has to be soldered directly to PCB, without the header between matrix and PCB.
Also there is no holes for USB or power on the head because I used custom PCB and didn't need them, I do everything over BT.
There are two versions, for servos with plastic gears and for servos with metal gears which are a little bigger.
