Following PCB's are develop universal for some kind of application depends on
PCB set up.

Variant of STN-A,
RS232-RS485 is able to fill at the same time two functions:
1. Interface between STN/SN and PC. One STN can have more than one PC interface.
2. Master of STN which is responsible for network timing.
STN-A, RS485-RS485
Variant of STN-A which is able to be a bridge between current STN and SN
or it can be used as STN-XPressNet interface.
STN-A, RS485-Loconet
Variant of STN-A which is able to serve as Loconet interface.

Variant of STN-A, Tower is able to control railroad
panel or it's part. One PCB can control up to 64 keys and up to 128 LED.
Firmware in microcontroller is able to serve many kind of railroad objects for
control and show railroad status. Current function depends only on activated
objects by data table via STN itself.

STN-BV2 is universal microcontroler PCB with up to 32 pins for control and power end applications. Firmware in microcontroller is able to serve many kind of railroad objects. Applications (in present day STN-CV2, STN-DV2 and STN-G) can be plug-in in any combinations and orders. Current function depends only on activated objects by data table via STN itself.
STN-CV2 is application for STN-BV2 which is focused to motor controled switches.
PCB is able to control real end positions of toes (depends on setup). On PCB
are two current detector inputs for two insulated section of track. One of them
has priority usage for switch.

STN-DV2 is application for STN-BV2 which is focused to control signals and coil
controled switches. PCB is able to control up to 8 pins. Order of pins, input/output,
active edge and modulations is free to configure via STN. PCB is also able to
control up to one current detector and up to one power detector. PCB fit to
FREMO "Wattenscheider Schächt" and by relevants Signal and Block object
is able to control relevant part of track by velocity status of dependend blocks
on active route. Velocity itself is not depend on railroad than object Signal
can be configure to show how current velocity looks on current railroad without
any dependence to block mechanism.

STN-E is support PCB for STN-A, Tower for easy attachment of railroad control
panel. Usage of this PCB is not necessary.

STN-G is application for STN-BV2 which is able to serve up to four current detectors and up to one power detector.

You can fill in number of PCB's and its variants. At the end you will have summary
list of parts with supplier's part numbering and approximate price. You can
also modify table by hw setup of PCB's by your requirement.
