DS203 (Mini DSO / DSO Quad) Start Production Now

It’s a long time pass since we posted the first preview of this amazing Multi-channel pocket oscilloscope. In later January the prototyping machine come out, after a period of testing, bure found many bugs in both hardware and software, so it took about 2 month to improve the design and fixed the bugs.

Now the hardware version change from v1.0 to the v2.6 . After the numerous times software update, the DS203 (Mini DSO / DSO Quad) finally near completion. Now the 500 units small batch production is processing, you will see the DS203 (Mini DSO / DSO Quad) soon.

Here is the latest schematic of the latest hardware version v2.6.

It fixed some channel interference and the measurement range issue. And you can find that the battery charger design is more safe than the DS0201 (DSO Nano).
