 +The Chinese Pro Micro clones have a 5V converter on board. 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 over the RAW input again! Check the

 +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.

 +==== Software ====
 +Connect an AVR programmer to the Pro Micro: +5V, GND, Reset, MISO, MOSI, SCLK.\\
 +! It should be the Reset pin on the Pro Micro board not the one of the connector !\\
 +
 +With the Avrdude erase the Arduino Pro Micro:\\
 +  $ sudo avrdude -p m32u4 -c stk500v2 -P /​dev/​ttyACM0 -e
 +
 +Set the fuses like that: lowFuse 0xFF, highFuse 0xD9, extendedFuse 0xC3:\\
 +  $ sudo avrdude -p m32u4 -c stk500v2 -P /​dev/​ttyACM0 -U lfuse:​w:​0xFF:​m
 +  $ sudo avrdude -p m32u4 -c stk500v2 -P /​dev/​ttyACM0 -U hfuse:​w:​0xD9:​m
 +  $ sudo avrdude -p m32u4 -c stk500v2 -P /​dev/​ttyACM0 -U efuse:​w:​0xC3:​m
 +
 +Burn the ATMega32U4-usbdevice_dfu-1_0_0.hex file on the Pro Micro. The file is included in the megaUSB_DFU_Bootloaders_2 folder:\\
 +[[http://​make.kosakalab.com/​archives/​megaUSB_DFU_Bootloaders_2.zip]]\\
 +  $ sudo avrdude ​ -p m32u4 -c stk500v2 -P /​dev/​ttyACM0 -U flash:​w:​ATMega32U4-usbdevice_dfu-1_0_0.hex:​i
 +
 +Set Lock-Bits 0xEF:\\
 +  $ sudo avrdude -p m32u4 -c stk500v2 -P /​dev/​ttyACM0 -U lock:​w:​0xEF:​m
 +
 +Run the [[http://​www.atmel.com/​tools/​FLIP.aspx|Atmel Flip-Tools]] like it's described at [[http://​make.kosakalab.com/​make/​electronic-work/​avrisp-mk2/​leo-r3_avrisp-mk2_en//​|Kimio Kosakas page]].\\
 +Upload that file:​[[http://​make.kosakalab.com/​archives/​AVRISP-MKII_ATmega32u4.zip]].\\
 +
 +That's it!
 +
 +Test it with an Atmega 328p:\\
 +  $ sudo avrdude -p m328p -c avrispmkII -P usb -U flash:​w:​optiboot_atmega328.hex:​i
