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

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.


LPF2 is also known as Powered Up - ref.

The Bluetooth hub is documented: https://github.com/lego/lego-ble-wireless-protocol-docs . This carries a large gh-pages branch & corresponding web site.

Philo also has useful information.

This doesn't answer the original question but I believe anyone searching for info will benefit from the connection.
