Hello Bafangers.

New K1 Flash v3 will be out soon.
Running over Windows and Chrome.

It is user friendly, simple, fast, no installation, no passwords. And also firmware update from cloud.

Check the web aplication at www.k1ebikes.com/flash3
Will be updateing the page and adding some features, like power graph, settings memory, firmware filter, battery info ...

The plan was to run it also from Android phone, but GPT did tricked me. ;) So this is not happening now, but will look into this later and rework. Now need a little rest.

Just got one spare M620 controller and to my surprise it is FC2.0 version. Even more surprised, firmware is from 2023. Till now I saw only FC1.1 and a few FC1.0
Anybody is using this controller? Have you noticed some difference?
