Design checklist

The microprocessor used on this module, like all CMOS devices, can be driven into a latch-
up condition if any I/O pin is driven outside of its associated power rail. Care must be taken
to:

Latch-up is a condition that can cause excessive current draw and result in excessive
heating of the microprocessor or its power supplies. This excessive heating can
permanently damage the microprocessor and/or its supporting components.
