Hi ,

supporter for the feature request smiley.

GaN FETs will be a great feature addition, i think the limitation comes with the continuous current capacity (not sure but is my analysis).

There is an other company (EPC) as well and this video is their showcase of motor drivers for robots and ebikes

There are few GaN FETs with integrated gatedrives - https://epc-co.com/epc/Products/eGaNFETsandICs/EPC2152.aspx

The GaN FETs are better interms of thermal properties as well

These are just switches, they are already supported by the firmware, but... Low current limits,  high RDSon, expensive. What's the point?

I think the point is super high speed switch frequency for a more quiet operation.

Probably not a need for e skate but some robotics (and other) projects could benefit.
