QS95 Current Measurement (3.3V Supply)
--------------------------------------

QS95 module current consumption can be determined via the integrated shunt resistor between **Pin 49** and **Pin 50**. 

To calculate the 3.3V supply current, measure the differential voltage across these pins and multiply the measured value by 10 (scaling factor: 10 A/V):

.. math::

   I_{\text{3.3V}} = 10 \times V_{\text{measured}}

.. note::
   
   **Quick Example:** A measured voltage of :math:`100\text{ mV}` across Pins 49 and 50 corresponds to a current consumption of :math:`1.0\text{ A}`.
