Voltage not reading correctly

Hey folks,

just got myself a nano, I made the mistake of getting one on ebay and now I think I’m paying for it. It has the newer bootloader, and I figured out how to get around that finally, got BenF on there… but I am having a strange issue.

When I attach the probe to the test point on the nano, the square wave is reaaaaly tiny at 1v/div - I have to crank it all the way to 0.1v/div to get it to display like other units that I’ve seen on Youtube… Here is a screenshot:

Also, I have an attiny24 chip that I set up to output clock at 1mhz, I used my Saleae logic probe to grab this, so I am sure it’s working:

But I can’t get a square wave on my DSO at all using any setting… I am a bit of a noob, but I think something is wrong here. Anyone have any ideas for me?

Thanks a lot for your help

Cann’t see the picture.
Please note that the Analog bandwidth of DSO Nano is 0~200kHz, it can not be used to measure the 1Mhz signal.


Howdy Mark,

I have a new V2, bought from Seeed, that I am told cannot be upgraded to Benf 3.64.
If that is what you did, could you tell me how you did it?
Thanks, CZ
