Do you mean by “industrial sensors with Grove port”?
Hi, Grove connector supports more than 20mA level.
Have you tried the firmware upgrade on Page 3 of this manual: http://www.seeedstudio.com/document/pdf/DSO%20Nano%20V3%20User%20Manual%202.pdf ?
You can get the raw data from the following code:
sampleV = analogRead(inPinV); //Read in raw voltage signal
sampleI = analogRead(inPinI); //Read in raw current signal
Thanks for adding this new idea and we will review it.
The I2C address for Grove RGB LCD Backlight is fixed by hardware. If you would like to have multiple devices running on Arduino at the same time, you can check this Soft_I2C library: https://github.com/loovee/Arduino_SoftI2C .
