Hi, I’m using the Cube orange+ with a standard carrier board. In the documentation, it was stated that the ADC IN -pin supports voltages up to 6,6 volts, but it seems to measure signal just up to 3,3 volts. I would like to connect a sensor with a voltage range of 0…5 volts, but not sure can this be done with a standard carrier board. Do I need an external voltage divider to scale the sensor voltage, or does the standard board have one, which can be enabled?
I think the ADC input is 3.3v maximum on most carrier boards.
The Kore carrier has a 6.6v maximum.
You would need a voltage divider like 5.6k and 10k
Question regarding ADC for standard carrier boards, if I wanted to have an extra ADC input using the ADS-B IN Carrier Board, can I use a converter like ADS1115 and then use an I2C input?
What do you need to measure? There’s supported ways to measure temperature for example.
Depending on what you want to measure, you could just use the second battery voltage or current monitor if not already occupied. It’s also a 3.3v input.
