My power and swr meter gets a big colorful 4.3 RA8875 display. The original firmware was designed by Loftur and uses a ILI9341 TFT display. My sketch is a hacked version and can be used for 4.3, 5 or even 7" RA8875 displays.
For more information please look first at Loftur's page [ Ссылка ] if you like a colorful and very sharp display please visit RadioStuff

Have fun to build your own big meter.
