I recently purchased DS203 HW V2.72.
Only the serial number is displayed.
The license number is not displayed.
It is also not displayed in DFU mode, so I am having trouble.
The serial number is “82 15 B2 B0”.
Hi,
So you bought this product: DSO Quad - 4 Channel Digital Storage Oscilloscope
Here are some resources of it:
DSO Quad | Seeed Studio Wiki
Please notice that there are more articles on the left sidebar:
May I know when and where you bought it?
Hi,
Thank you for contacting me.
It was a gift from a friend.
The reason is that instead of the original software,
he installed software from a developer other than the manufacturer,
and when he turned the switch OFF and then ON to restart,
it froze on the startup screen.
He said that he couldn’t handle it himself,
so he would like to have it if you would like.
In other words, he broke it.
Probably a retailer through an agency.
