    Hi Steven, The LED resistor value is 10 Ohms. Using a double sided VHB tape around the perimeter of the display to attach the polycarb block would be a better solution. Any liquids that enter the d...

    Hi Steven, You should be ok with that thickness as long as there is very little air gap between the display and the polycarbonate. Ted

    Hi Serge, Please refer to our example code listed here : https://support.newhavendisplay.com/hc/en-us/articles/4415233794583-NHD-C0220BA-FSW-FTW-with-Arduino  Best Regards, Ted

    Hi Ihab, The NHD-2.4-240320CF-CSXN#-F display requires a 3.3V I/O logic level to drive the command and data lines. You may need to use logic level shifters from the Uno to the display, or change th...

    Hi Steven, Adding a polycarbonate cover glass over the display is a common solution to help protect the display from external forces that may cause damage to the display.  Keep in mind that adding ...

    Hi Ihab, Unfortunately the ST7789V controller on the NHD-2.4-240320CF-CSXN#-F display does not support a DMA transfer directly to it's frame buffer.  An 8-bit or 16-bit 8080-II parallel MCU interfa...

    The voltage levels look to be close, however I will need to make some measurements here to confirm if they are high enough. Please check the starting value for the Electronic Volume register as it ...

    Hi Daniel, We have used these 1uf capacitors from Digikey: https://www.digikey.com/en/products/detail/kemet/C0805C105Z4VAC7800/2211782?s=N4IgTCBcDaIMwE4EFoAcAGAjJ5ZkDsATEAXQF8g  To reduce the cable...

    Hi Daniel, Unfortunately the 10uf caps will not produce the same output voltage required for the LCD contrast to be in the proper range.  We typically use 1uf ceramic surface mount capacitors to st...
