but as for things that really matter, like "what voltage is VDD"
The regulator can output either 1.8V or 3.0V, that is why I just show VDD.
they ought to build it, measure the capacitance, then add enough to get to 15pF.
I will check into this.
I accept and encourage criticism, but saying that the device is just a crappy scope isn't fair. The scope is just one of many modes of the device.
I understand that with today's scopes specs in the GS/s, something like 4 MS/s is less appealing, but it is still useful for many applications.
The device is also a protocol sniffer for I2C, SPI, and UART; it can sample digital data at 16MS/s; it can measure frequency on digital signals up to 16MHz; it has an Arbitrary waveform generator; it can generate component curve traces by using the AWG along with the scope.; it can connect to a tablet or computer. All this in a device that weighs about 30grams. Even if you don't use it as a watch, it can be a useful tool that you can leave on your toolbox without taking much space.
I just made a new video today, check it out if you are interested:
