Information about boards

Take care with the locking mechanisms (catches and centring pins) when you are replacing boards
or components on boards.
To prevent damage to the board or the components and conductors on it, please take care when you
insert or remove boards. Make sure expansion boards are inserted straight.
Never use sharp objects (screwdrivers) for leverage.

engaging and releasing them are green coloured or marked with green dots (Touchpoints).

You must always discharge static build up (e.g. by touching a
grounded object) before working.
The equipment and tools you use must be free of static charges.
Always hold boards with ESDs by their edges.
Never touch pins or conductors on boards fitted with ESDs.
