What are the voltage limits on the ADC?
My question was what are the input voltage limits on the ADC? Are there any shield products or recommendations to scale to +- 10 Volts if needed?
We are looking to send some collected data over Bluetooth to another module.
@robert-hh Thanks for the reply. I am heading down that path.

@Ryan-Finn The range depends on the attenuation being set. The native range is 0-1V, with attenuation it's 0-3.3V. Anything beyond that will damage the device. If you need a range of +/-10V, you will most probably need an external active level shifter and attenuator, like an op-amp.
