Interested in this controller as well. It's a little light on the voltage for my application but it seems very well thought out. This or Tronics larger controller whenever it gets released. 3Shul just seems a little slap and dash for my liking.
I've used the previous generation of their devices (The "metr") and, from a data logging/analytics perspective it's absolutely, hands down, the king of the hill by MILES compared to anything else I've had exposure to. It's also really good for on-the-fly adjustment of literally any setting the VESC offers. Adding a nice display is really just icing on the cake, imo.
You can certainly get the Minnie and use it headless or with a cheap Andriod mounted permanently, but I like the idea of a more permanent "part of the bike" feel of the dedicate display.
