Hallo Leute,
hier ist mein kleines Projekt, pandora ist eine Platine die in eins von den 1-Euro Gehäusen rein passt. Auf der selbst geätzten Platine sitzt ein ATmega48, 10 MHz Quarz, 6 MOSFETs, ein myUSBtoUART und Kleinfutter.
Noch kurz die wichtigen Daten:
Eingangsspannung: 7-28 V
Ausgangsspannung: 7-28 V
Schaltstrom: 2,5 A
Platinen Layout als PDF

Schaltplan
Als Firmware läuft folgender code:
