What's the difference between the KmeterISO and the Kmeter units?

Surely this is a simple question? Is it impossible to put the Atom Lite into USB mode?

This is the error I get from M5Burner when string to select "USB Mode" in the UIFlow_Lite item in M5Burner:

Selecting "USB" mode in the burner config results in an error.

The quick start docs only say how to get the Atom Matrix version (not the Atom Lite version) into USB mode: "Press and hold the middle button while powering on, and do not release it until LED color change to blue". With the Atom Lite version the LED never changes blue when holding the button - just flashes green...

@world101 I'm having the same problem... this page only seems to give the method of getting the Atom Matrix into offline mode... I have the Atom Lite... I've tried holding the middle button on startup and the LED never goes blue... just green...

I'd like to have dimmable 24v LED strip lights driven from a MQTT server. Will the ATOM PWM Kit do this?

Your page only mentions 12v, but the unit has 12-24v printed on it... If the input is 24v will the output be 24v?
