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

-==== Pro Micro Modification ====

-** TX Line Connection:​**\\ 
-Solder a wire between the resistor of the TX LED and A0.\\

-** Close the Jumper: **\\ 
-The chinese Pro Micro clones don`t have the 3.3V converter on the board (like the Sparkfun board) - instead 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 again! Check the  
-[[http://​cdn.sparkfun.com/​datasheets/​Dev/​Arduino/​Boards/​SparkFun_Pro_Micro_v13a.pdf|original sparkfun schematic]] for details.\\ 
-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.
