Hi, the MIC 2775 in the schematics of the 3.0e Board is MIC2775-46BM5. This is for 5.0 Volt. The correct type for 3.3 Volt is MIC2775-29BM5. best regards martin -- View this message in context: http://www.nabble.com/MIC-2775-Reset-Chip-tp18649624p18649624.html Sent from the MicroControllers - Ethernut mailing list archive at Nabble.com.
