* All analog sensors will need to have the same operational voltage range. Many analog sensors are set to use 0v to 5v by default, but some can go -5v to +5v, some even up to 5.5v.
* The `AREF` pin, by default, is the same voltage as the MCU. Analog sensors must not exceed this voltage limit.
* 5v analog sensor signal pins**must** be [level converted](https://randomnerdtutorials.com/how-to-level-shift-5v-to-3-3v/) in order to connect to 3.3v MCUs.

* The SAM/SAMD family of MCUs (e.g. Due, Zero, MKR, etc.) as well as the RasPi Pico and others support different bit resolutions for analog/PWM pins, but also may limit how many pins are able to use these higher resolutions. See the datasheet of your MCU for details.
