To open the layout lay6 you need to use Sprint Layout 6.0. The demo version is enough to visualize the pcb.
There is no official schematics. The connections can be quite easily followed using the layout software. If you need some basic reference you can read the Angelia-Anan100D schematic since parts of it are the same like RX front-ends. If you have done by your own the schematics or part of it feel free to open a pull requests.
