RT1, RT2 and RYII. A closed case on the XY plane with the pins down through the board. Pin 1 is at the origin; the pins are placed as the maker's bottom-view PCB layout draws
them, seen from above (the layout turned over about its horizontal axis): along it to +X, its next row towards +Y. Dimensions from the
makers' data sheets in the README."""
