I didn’t make the PCB, why should I? Posted by Nazar Sliunchenko at I’ve already written about USBasp, so I’m not gonna do it again. All I’ve got to qvr910 is change some connections on the board according to the schematic of AVR and reload the firmware.
A new Com port will appear, check your Device Manager. But there is an easier way! If you are just learning programming microcontrollers you might mess up with the fuse bits.
That’s what my programmet post is gonna be about. I have my previous version of USBasp programmer.
To save it and use it in your projects again you need a high voltage programmer like STK Plug in the programmer. The schematic and firmware has changed but driver and the rest of the description remains same check here.
STK is a standard Atmel protocol. I personally prefer this programmer because it supports more chips and works with most software. I’ve tried all three versions of firmware and all of them work very well. All you’ve got to do is load suitable firmware.
AVR USB step by step instructions for assembly –
The description is similar to AVR Jumper J3 is used for low frequency programming. So any program should support this programmer my gues. Here are three archives containing hex-files and drivers for Windows. You don’t even need a computer or programmer.

And then It’s got better. If you know Russian you can check here. So, just build it and load one of three firmwares. Newer Post Older Post Home. And as a result your controller programme responding. One guy has made a huge job.
I’ve already told you about USBasp, it’s a great programmer, the fastest I know. This schematic is different from USBasp that I’ve posted here.
AVR910 USB step by step instructions for assembly
You might need the “low frequency” programming porgrammer internal oscillator of the controller the one you are about to program is set to kHz. Jumper J1 is used for loading firmware to this programmer through the same ISP connector. To use it with Arduino go to Here’s the schematic of AVR Like I said, it’s a universal schematic diagram. He adopted those three firmwares for one hardware.
