LEGO PoweredUp! compatible plug

Recently (years, not decades) LEGO introduced a new family of motors, sensors and control system – it was and is a bit confusing, but whether you think of LEGO WeDo, Control+, Powered Up, Spike Prime or the new Mindstorms 51515 it is all based around common backbone and, especially, a common connector – a 6-pole non-stackable plug.

Which, by sheer coincidence naturally, is completely incompatible with the old Power Functions connector from LEGO, who also claimed not to intend to manufacture an adapter cable because reasons.

Before someone jumps at me: I do understand WHY. And no, I don’t mean ‘to sell all motors again’. There is a technical reason not to make an adapter cable. You see, when the Power Functions system was designed, the main source of power was a dumb battery box. Even equipped with a cheaply made switch, a 6AA battery box can withstand all the power draw that stacked multiple motors can realistically take and it is the batteries that will fade before the box melts
