Hello everyone! Well we’ve been selling the Proxmark3 Easy for some time now, but we only recently discovered this while reviewing the codebase for an upcoming PR we’re working on. There is a parameter you can set in the Makefile.platform that specifically changes the LED output mapping for the Proxmark3 Easy which brings it in line with other types of Proxmark3 devices including the RDV4.
LED_ORDER=PM3EASY
For whatever reason, it appears the design of the Easy mapped LEDs to different GPIOs than other hardware versions. Someone caught this and put this flag in code, but we just now discovered it. We’re making this announcement in case anyone wants to update their Makefile.platform and recompile to try it out. We’ve also updated our PM3 Guide post to mention it as well.
