Try to google for "plug case"

@Lecram71 I always add a cap to the Vcc, just to make sure. Never failed for me.
Wow, thats great !
Could you please post an AliExpress link to the displays you used ?
Did you add some 47 uF Cap between Vcc and gnd on the nRF module ?
BTW, i use these, i don't need it so colorfull
