BTT ebb36-42 Gen2 v1.0 Support

[Flam723]

Describe the feature or hardware support you'd like

Can you please add support of the BTT ebb36-42 Gen2 v1.0 to the Toolhead list?

Additional context or information

this would be great!!

I third this, im trying to convert a ebb36-42v1.2 to gen2, luckily i don't need the lis2dw because i have adxl on cartographer and hopping to work that in

Here is what I have working on mine, but I have not tested every port and feature. I've used the accelerometer so that is working for sure as well.

looking good.
