I originally purchased the unit as a backup to a unit that cost over a hundred dollars, but that unit fails to recognize the chips 9/10 times; this little inexpensive unit works flawlessly EVERY TIME! The unit is small and takes up very little space, many times I leave it connected to the USB port on the PC for quick access. Review: Came in perfect condition. I was able to flash an ave microcontroller on Linux without the need to update any usb drivers. I used avrdude on a raspberry pi. ## Features - This USBASP Programmer only supports WINDOWS system.

Not all Ender 3 or Ender 3 Pro printers ship with a bootloader. You can use this to either burn a bootloader and then flash the firmware via USB, or you can use this to flash the firmware directly to the main board. I have used it to burn a bootloader onto a Creality 1.1.3 board, and then flashed the firmware from the source code Creality has available on their site. **Q: I have an Ender 3 without a bootloader, will this work to flash Marlin firmware directly to the board without installing a bootloader?** A: Yes, as USBAsp I was able to load a bootloader on an Ender3 board. **Q: Will this programmer work with win 7 and atmel studio 7? where is the operating instructions?** A: Here is document link, https://protostack.com.au/download/Users%20Guide%20(AC-PG-USBASP-UG-V2.0).pdf **Q: On the instructions pdf, 4.2.3 procedure, step d, where do i find a bootloader binary file to go from this thing to the ender 3?** A: Believe I got the boot loader from YouTube video on how to. You should be able to get it from the creakily site also ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***A on 27 September 2023* I have used this unit consistently for several months and flashed several hundred megaprocessors using this unit and the free AVRDUDESS software.
