Does anyone have the new Power Function 2.0 specification or pin out?

I don't think an official one has been released, but there are some people who have looked into reverse engineering it. Here's one example I found: eurobricks.com/forum/index.php?/forums/topic/… – Alexander O'Mara Sep 22 '18 at 18:04

Why is this tagged with powered-up, are we not confusing power functions with powered up here? – Bjarke Freund-Hansen Nov 6 '18 at 16:41
I'm not sure exactly what you are looking for in terms of a spec, but here's the pinout from the Eurobricks thread mentioned by Alexander O'Mara with some help from this post:
Pin 1 - Motor
Pin 2 - Motor
Pin 3 - GND (0v)
Pin 4 - VCC (3.3v)
Pin 5 - ID 1 (UART TX for active devices)
Pin 6 - ID 2 (UART RX for active devices)
The basic spec for motors is that they are given continuous 3.3V power on pins 3 and 4, voltages to drive the motor on pins 1 and 2, and pins 5 and 6 are used to identify the type of motor that is attached. For the basic motors, I believe that this is simply a known resistance between pins 5 and 6.

Additionally, pin 5 is UART Tx and pin 6 UART Rx when a UART devices (sensors and motors with encoders) are connected. – David Lechner Jun 26 at 16:22
