Using the mikroProg
===================
WARNING: This will most certainly overwrite the bootloader that was factory
installed in FLASH!
WARNINGS:
1. Following there steps will most certainly overwrite the bootloader
that was factory installed in FLASH!
2. Due to the position and orientation of the mikroProg connector you
may lose functionality: If you attach mikroProg to the red side of
the board, you will not be able to use the Arduino Shield Connector
while the mikroProg connected. If you attach mikroProg to the white
side of the board, you will similarly lose access to mikroBUS
connectors A and D.
