I found and old RCA Lyra mp3 player with liquid crystal backlight display and that gave me an idea. Can you put a RGB backlight display color selector on the flipper zero?
Ah, it’s not possible with the screen we chose for Flipper Zero. It’s yellow only.
Ok, I didn’t know, thanks for the answer.
We have looked at display with RGB backlight but it slightly bigger and not fit in our case. Also it required more 3 MCU legs or additional IC to control colors.
Teoretically, you can use non-backlight display (with lens on side) and set cheap smart 2020 leds like APA-102 (requires 2 legs) or APA-104 (requires one leg, but haven’t seen 2020 version).
But I think it’s overkill. Let’s leave it for modders.
