ICSP interface
On the right side of the board there are 6 pads for the ICSP interface (in-circuit serial programming). They have been
setup in a 1.27mm grid. Since a bootloader is already preinstalled on the ATMEGA328P at the factory, this interface is
normally no longer required for later operation of the control board. Therefore, no pin header has been installed.
