Take a look at whats to come, its my FT800 pcb but complete 🙂 Its untested but should work. I took a couple ideas from the GameDuino2 and there forum 🙂 The guys there are awesome!
This has everything you need to control a 4.3″ tft (or others if pinning is the same). Backlight, Audio, Basic SPI Pinout that wont kill you with wiring. For audio you have to supply 5v to 5VA for a stable audio signal. Also connect 3.3v to VCC. So this may need 2 supplies. Audio is a hassle i which not to touch so i left it this way… (for now)
