NOTICE
When an air pump is connected to I/O interface, the terminals of air pump cannot be
exposed to the air, to avoid short circuit. If that happens, you need to cut them to an
appropriate length. For matching all I/O interfaces, terminals of air pump will be slightly
longer. Figure 3.11 and Figure 3.12 show the standard and non-standard connection of
the terminals respectively.
