Description
Purpose
A (piggy-back) print for providing feedback via the (LENZ) RS-Bus to the Command Station. The print is based on SMD Technology, and (except for one standard CNY17 opto coupler and the connectors) all components can be assembled by JLCPCB. Total costs for 10 PCBs (including components, assembly and shipping) will be around 20 Euro.
RS-bus software
An Arduino library, as well as details regarding the RS-Bus operation, can be found on my GitHub pages. This work was inspired by the RS-Bus description on the der MOBA website. See also the DCC Train website.
THT version
Note that I've also created a PCB for traditional (through hole) components, for those who want to assemble their own boards.
