### Backlight Control ### 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.
