Designing a signaling system with cpNode (CMRI on Arduino)

Clinician:

Chuck and Seth will describe their experiences designing and implementing Model Railroad Signaling Systems and how they have used the cpNode system they developed, to streamline the process.
They will discuss power distribution and detection topologies, setting up signal locations, dividing the layout into blocks, cabling, cost optimization strategies and much more.

Format:
