Good commercial leaflet !
Good website !
Good idea !
Bel enthousiasm !
but : What is the price ? I can't find it.
but IMHO of retire electronicien :
useless product, simple gadget
This is misleading users. As soon as they will want to see something other than a LED that flashes they will be very disappointed.
With 100 kHz bandwidth it is impossible to see an I2C transaction !
I2C clock is 100 kHz, so to see I2C clock signals "approximatively rectangular" it is mandatory to have minimum 7 time bandpass so 700 kHz.
With your product you see only a sinusoidal clock and amplitude is false because you have 100 kHz bandwidth ---> At bandwidth point amplitude is divided by 2, it's the definition of bandwidth point.
With a bandwidth of 100 kHz users can do very little measurements.
The minimum bandpass to work with Arduino is 1 MHz, I recommend bandpass higher than 40 MHz.
You seem to forget that avr on Arduino boards is able to deliver signals up to 8 MHz (with the timers).
Perhaps if the product costs less than $ 25 ?
Idea is good but you have to change ADC for one with higher bandpass.
Sorry, but franchising is for me an essential quality.
