### Analogs

* Gain sets the scale in uS/Volt. A 0-3.3V signal with a max channel value of 1024us works out to 1024/3.3=310 (Which is the GUI default)
* Offset allows you to tweak the zero point for your signal, if your potentiometer doesn't go all the way to zero for instance.
* You can invert an analog channel instead of re-wiring. Set the gain to negative (-310.3) and set offset to 1024.&#x20;
* You can use any of the analog pins as digital inputs as well see [digital-inputs](../../getting-started/wiring/digital-inputs "mention")
*   If you have a board with battery monitor such as the **DTQSYS board,** the first analog channel will show Battery Voltage.&#x20;

    * You can transmit to your radio on a channel and setup the radio to signal when the battery is low.
    * On the **DTQSYS board** the voltage divider is made up of a 1K and 10K resistor to the formula to calculate the voltage is. This will be improved in the future :wink:
      * Ch = (V \* 1/11 \* GAIN) + OFFSET

### Aux Functions

You can select various auxiliary functions to be output on this page. Allows raw output values of the Gyrometer or Accelerometer

Choose the output and channel you want to output it on.

If you want more outputs please create an issue on Github.\

Bluetooth RSSI is apparently broken.
