I just purchased the OLED 128×64 with the intent to convert it to a 3.3V part. However, the schematic listed on the Wiki page is out of date and doesn’t match the parts on my version of the board. Please upload a new schematic. Thanks!
For what it’s worth, this is what I intend to do:
- Remove the two 5V pullup resistors from the SCL and SCK inputs.
- Bridge across the two level shifting transistors (pin 2 to pin 3)
- Bridge across the 5V input and 3.3V output of the LDO voltage regulator. (this part is different on V1.1)
