"Operating the ACRICHE A4 emitter requires a bridge rectifier and resistors at a minimum, since theElSor pisze:Jeśli LED przewodzi 1 kierunku to jak najbardziej taki układ się sprawdzi. W poprzednim pdfie przebiegi sugerowały, że w 2ch.
architecture of the A4 has been modified from the earlier versions of the Acriche family(A2, A3),
which did not need a bridge. This architecture has a string of LEDs in one direction only,
compared to the previous version which has strings in both directions, thereby not requiring the
diode bridge previously. Utilizing the new architecture, we are able to reduce the number of LEDs
needed, thereby reducing package size and price."
czyli to co podałem wcześniej jest nieprawidłowe... przewodzi w 2 kierunkach
