Information about "Das RS" and "Das mini" hardware using DRV8313/DRV8320

I already saw a while ago that there is a hardware config file on Benjamins github available about a hardware called "DAS_RS" that uses an DRV8313 with 0.01 Ohm phase shunts and I was interested in this board but couldn't find anything about it on the internet. Now a few weeks ago a new board called "DAS_MINI" popped up that uses a DRV8320 and also three phase shunts and I am even more curious about that design but also didn't find anything about it. You can see what I am talking about here: https://github.com/vedderb/bldc/tree/master/hwconf

So my question is, if someone knows more about that hardware or the person designing it. I think at least Benjamin should know something about it when confirming pull requests.

I just had a quick look into the datasheet of the TI DRV832X devices and the DRV8323R with build in buck converter and 3 current sense amps looks like a perfect candidate for a very small VESC with all the great new features it delivers like 100% duty cycle and stuff like that. At the moment I am not quite sure how that works, but it sounds amazing.

It would be nice to hear from you Shackmeister: https://github.com/Shackmeister :)

Hi :) 

We are a company called UAV components, Uavcomponents.net, and we are making Electronics and software for UAV's and robots among other things :)

We are coming out with a series of Vesc based motorcontrollers in cooperation with Vedder.

If you want some more info on our mini version, please send me a PM. Otherwise I can tell you it's small, 12s compatible and pretty damn cool if you ask me (or Vedder ) :p
