Review: Beware of the high memory glitch ! - 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! Review: Works perfectly - These worked perfectly to do some ISCP programming on freshly manufactured Arduino-compatible boards with blank microcontrollers. I was also able to use it with a board with a ZIF socket for DIP parts. I've programmed about 200 boards without any issues. ## Features - 【Support 3.3V and 5V】: Supports 3.3V and 5V microcontrollers and circuit boards. The output voltage can be adjusted easily by the jumper cap! - 【Easy to Use】: Applicable to WIN8.1 / 8/7 / XP 32-bit / 64-bit computer. It can be directly connected to the USB interface of the computer, which is very convenient to use. (Please note: this product is not suitable for WIN10) - 【Easy to Program】: Programming interface is reserved, you can upgrade the downloader firmware by yourself. Programming software: AVR_fighter, PROGISP1.66, PROGISP1.67, PROGISP1.68, can also compile lower or higher software, programming is very convenient. - 【Automatic Speed Regulation】: AUTOSPEED automatic speed control firmware, the downloader will automatically track the frequency of the chip to be programmed and automatically change the speed to achieve automatic speed control. - 【10PIN to 6PIN Converter】: Equipped with standard ATMEL ISP10 to ISP6 port converter. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0885RKVMC | | Best Sellers Rank | #5,270 in USB Cables | | Customer Reviews | 4.2 4.2 out of 5 stars (154) | | Date First Available | May 6, 2020 | | Item Weight | 1.44 ounces | | Manufacturer | KeeYees | | Package Dimensions | 6.34 x 5.28 x 0.98 inches | ## Images ![KeeYees 2pcs Downloader Programmer for USBASP for ISP with Cable and 10Pin to 6Pin Adapter Board for 51 for AVR Series Microcontroller - Image 1](https://m.media-amazon.com/images/I/61JalIGEdcL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.
