I have a NEXTION ILI9341 3.2 inch TFT LCD Display (TFT_320QTV_s341) and a MEGA I plan to use to control WS2812B Led Strip. The issue is that the 40 pin adapter will cover the 5 volts pin in the Mega and I am not sure I can use external AC/DC Adapter to control all both the screen and the strips. Can this be done?
Is there an adapter that allow the digital pins on the MEGA to be exposed to jumper cables with the screen attached to it?
Thanks.
In any case you MUST use an external 5v power supply to both a screen and a led strip.
Arduino is not a power supply, its "5v" pin is for weak current modules like a sensor.
Additionally - it is a rare case that Nextion display used as a shield. Since Nextion uses a Serial to talk with Arduino - it usually doesn't use a 40pin connector.
Are you sure that you have a screen with a Nextion interface?
This is the display I got: Amazon.com: NEXTION ILI9341 3.2 inch TFT LCD Display 320x240 Resistive Touch Screen for Mega-2560 only, not display from N e x t i o n Series : Industrial & Scientific
It came with a shield, but I guess I can skip that if that os possible.
