## Customer Reviews

### ⭐⭐⭐⭐⭐ They work!!
*by C***S on April 12, 2025*

Can’t speak for other suppliers programmers but these work very well with Aatiny chips.Ease of use is a real asset. Download the correct driver and start programming.

### ⭐⭐⭐⭐⭐ Beware of the high memory glitch !
*by B***E on April 12, 2022*

My boards worked right out of the box and had the 1.04 firmware. I was programming UNO's right and left.But I hit a glitch when I tried to program a Mega2560. It seems to work fine under the Arduino IDE but loading a big program (FlashForth) with avrdude was a total failure.It seems there is a firmware glitch in the 1.04 firmware for memory > 128K. After 2 days of effort I found an excellent website that explained the glitch and had a revised firmware 1.05. I flashed one of my usbasp's , uploaded Flashforth to my Mega2560, and it worked flawlessly!I don't know if I can put a website address here, but search for "Mega2560 usbasp mystery" and you will find it.On a side note, I see different jumper numbers on the reviews from the boards I got. Next to the 3.3V/5V 3 pin jumper is a 2 pin jumper labeled JP1. This is the pin I needed to short in order to program the usbasp module. Sitting by itself on the other side is a jumper without pins labeled JP3. I think this is the sck jumper but I have not needed to use it for anything. I would upload a picture, but I have a new Mega2560 FlashForth computer to play with right now!

### ⭐⭐⭐⭐⭐ Works well with AVRDude
*by H***E on August 24, 2024*

Both boards work as expected. The boards I received had outdated firmware, but it was easy to solder a jumper at JP2, and upgrade to the latest firmware (from 2011!) using AVRDude. Use one device to update the other, then swap JP2 from one board to the other, and update the second board as well.
