INTERPRETING COMPONENT DESIGNATIONS FOR TSYKLON LABS MODULES
As much as possible, we have tried to be very consistent with how our components are labeled on our Printed Circuit Boards (PCBs). Aside
from being consistent component to component, PCB to PCB, and module to module within our own products – we have also done as much
as possible to be consistent with standard naming conventions used by other module designers. The table below lists component types and
their designations. We will use 000 in place of the identifcation numbers normally used so that you can see what the component number
will look like. Most prefxes are one to two characters long, but can occasionally be three characters.

With regard to the numeric part of the component designation – 100 series numbers are for the PCB closest to the Front Panel. 200 series
numbers are the next PCB behind the frst, 300 series belong to the PCB behind that. While it would make sense that 400 series component
numbers are for the next PCB behind that, in some cases those components are on the PCB for the expander module. Make sense? Great,
go forth and build!
