Review on 🔌 KeeYees USBASP Downloader Programmer Set with Cable, 10Pin to 6Pin Adapter Board - Ideal for 51 & AVR Series Microcontrollers by Srinivasan Bennett

Update firmware with"avrdude -C avrdude.conf -p atmega8 -c usbasp -U" flash:w:usbasp.atmega8.2011-05-28.hex :i "-F -P usb" and use the libusb-win32 driver and everything looks fine from a hardware point of view. Good deal for these as you will need a pair (2x) to perform the flashing above. You will also need to either solder the connectors to the JP2 location or electrically connect them in some way to "self-flash" each other as well. All in all a good deal for a couple!
