From the project

REVIEW ONLY — NOT RELEASED — ALL HARDWARE TESTS NOTRUN.**

Native project: ../../RF2M.kicadpro, ../../RF2M.kicadsch, ../../RF2M.kicadpcb. E1 is preserved at m5b-e1 / 6931260`. E2 changes localized control copper, one ground-fill notch, PCB revision marking and the minimum connection-width threshold. Electrical schematic, BOM, RF structures and RF80 remain unchanged.
