- | ===== Paper-AVRISP mkII ==== | ||
- | Am AVRISP mkII clone made with Paper-PCBs. The board is based on the ProMicro with the Atmel32U4 chip. | ||

- | ** Close the Jumper ** | ||
- | In putting a little bit of solder on J1 of the Pro Micro Clone you close the jumper and bypass the voltage converter of the board. | ||

- | The cheap chinese clones don`t have the 3.3V converter on the board, they have a 5V converter. That means when powered over USB the Pro Micro runs on 4.7V. To close the jumper will avoid that (it´s next to the USB socket). But never power the Pro Micro again over the RAW input! Check the | ||
