  • I want to drive OpenLog from a 5V Arduino Pro Mini. The header is the OpenLog source file says “Input voltage on RX-I pin must not exceed 6V”. The datasheet of atmega328p says max input voltage VCC+0.5V which is 3.8V given the 3.3V VCC. Can I drive OpenLog from a 5V MCU without a level shifter?

  • I am looking at the schematic, the atmega328p runs at 3.3V and 16Mhz. According to the atmega328p’s datasheet this is outside the spec (13.33Mhz max at 3.3V). Am I missing something?

No public wish lists :(
