Sabvoton ML7260 controller

Hello everybody, I bought 3pcs of mentioned controllers and I have problem connecting it to the computer. Does anybody have experience with it? Also any additional info about this controller is highly welcome...

Here are photos of it, it is definitely beyond cheap chinese controllers and I really like how it is designed... And it was rather cheap too (90€). It is rated for 20s and 60A battery / 170A phase max. I am not sure if it is FOC, it seems more like sine to me.

Hi, I have also bought what looks like a slightly different revision of te same controller, I notice you have a missing 4 pin connector and I have a missing 8 pin.

I do think the signals from then are duplicated in the 30 pin connector, but i cannot find any wiring diagram for this 30 pin connector online despite 2 evenings of searching.

To connect ml7260 to computer you need old version ch340g chip drivers (1.4) version. On newest or or already existing drivers in the win 10 connection will not work probably because ch340g chip which is included with the controller cable is a clone that does not work with the latest drivers.
There are programmable and non-programmable versions of the ml7260 controller and you need program "ML Controller Paramter Setting.exe"
