 For a standard value a $2.0  \Omega$ resistor will be used. This may make the display a little bit less bright but won't change it very much.Vs - Vf) / If using the maximum forward voltage:
 ### Backlight Control
 Since this device will be battery-powered and the display is not needed most of the time it needs to be able to be controlled by software by the ESP32-S3. To do this a transistor will be added to the cathode pins to control the backlight with an io pin from the microcontroller.

+I chose [this mosfet](https://www.digikey.com/en/products/detail/infineon-technologies/IRLML2502TRPBF/811439) since it has very low resistance and should turn off and on with the 3.3V logic levels of the esp32-s3.
