This capacitor provides suppression of transients on the power supply. The PIO
module may well be used to power and control external electronics, in which case
there could be significant transients generated on the supply lines. Where possible
supply transients should be suppressed at source, so this component should not be
critical.
The PCB allows for a radial or axial capacitors. In order to build a low profile board,
the capacitor should lay on its side. An axial capacitor would be most secure in this
configuration, but there is limited length allocated and you probably don’t have one!

This pair of jumpers allow the interrupt daisy chain signals to be connected to the
RC2014 bus signal USER 2 (pin 38) and USER 3 (pin 39). To make use of this feature
you must use a backplane that is specifically designed to provide the necessary daisy
chain, such as Backplane SC107. The current official RC2014 backplanes do not
support this feature.
Alternatively the signals IEI and IEO can be found on connector P2 on the back edge
of the board. Dupont wires can be used to daisy chain these signals to other
modules.
