Deal with SD-card error

[SophiaDobko]

with the present version, power consumption increases when there is no SD-card or an SD-card error

[TillF]

This issue is hard to reproduce:
When powered via USB, everything works as expected.
When powered with 11.8 V via Vin, things seem to depend on the used SD-card:

• 32 GB HC1 from SanDisk, FAT32: works as expected, 20 mA in sleep mode (Vboard = 4.93 V)
• 32 GB from Sony, FAT32: SD-card not found, ~ 40 mA in sleep mode (Vboard = 4.93 V)

Board-Voltage when powered via USB are slightly lower:
san: 4.56 / 4.73 V
sony: 4.7 / 4.75 V

Note: Current in sleep mode drops considerably when SD-card is removed, increases beyond initial value when re-inserted.

Summary:
Cannot be fixed now. Try to collect more information, when the error occurs.

Hey Till, War das nicht andersherum, dass bei fehlender SD-Karte der Stromverbrauch höher war als mit und wir den Eindruck hatten der Arduino "schläft nicht richtig ein" wenn die SD-Karte fehlt? Ich wollte noch kurz nachfrage wegen unserer letzten Dienstreise, du rechnest das Auto wahrscheinlich selber ab, oder? Dann müsste ich gar keine Abrechnung machen diesmal. Viele Grüße, Sophia
