So, I just got one of those cute mini digital o'scopes -

ARM DSO 201 NANO DIGITAL MINI OSCILLOSCOPE 2Msps POCKET | eBay

and I'm trying to set it up. There has been interest in them here and figured this is as good a place as any to share some info.

Mine came with no manual. Anybody have a link to one?

Also trying to figure out how to add an SD card. The instructions from the seller say to format a micro SD card with FAT16 and copy some files to the root directory. I've done that but the 'scope doesn't like it - with the card plugged in the gizmo's screen is blank. Anybody have success with that?

Then there's the question of updating firmware... which I'll get to later, I hope.

I intend to do some testing and compare this thing against my Tektronix once I figure out how to make it work.
