RS-BUS-SMD

### 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](https://jlcpcb.com/). 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](https://github.com/aikopras/RSbus). This work was inspired by the RS-Bus description on the [der MOBA website](http://www.der-moba.de/index.php/RS-Rückmeldebus). See also the [DCC Train website](https://sites.google.com/site/dcctrains/rs-bus-feed). ### THT version ### Note that I've also created a [PCB for traditional (through hole) components](https://easyeda.com/aikopras/rs-bus-tht), for those who want to assemble their own boards.
