Hello there,

I bought the V2 of pixelblaze about 3 years ago. My led strip broke (corrosion…) and so I didn’t use it for a long time.  
Now I’ve got new stripes SK6812. It’s working so far but I can’t select GRBW mode. No ‘W’ mode at all.  
Can the V2 handle white channel or is it up to v3?  
If so, is there a way to buy the new version of pixelblaze somewhere in Europe to skip customs (they take ages sometimes)

Greetings from Germany

> If you have a recent version of Pixelblaze firmware (v2.18 or above, or any V3), you can update right from settings as long as your Pixelblaze is connected to the internet. If you can’t connect your Pixelblaze to the internet or that isn’t working for some reason, you can upload a firmware update file directly. More recent versions of V3 have a nice update tool at /recovery which can be used to update online or offline, and configure WiFi if necessary, and will provide status information durin…
