KeeYees 2pcs Downloader Programmer for USBASP for ISP with Cable and 10Pin to 6Pin Adapter Board for 51 for AVR Series Microcontroller

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!

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.

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.

I bought this to flash updated firmware to an Ender 3 3D printer with a 8 bit v1.1.4 mainboard. They work, but they need some modifications before they're truly usable. They come with outdated firmware and lack the pins and jumpers required to flash new firmware to the USB ASP programmers. I was able to solder in pins I had laying around from a different project to get them to work, but they should have been included by the manufacturer. Zero Amps Electronics on Youtube has great tutorials on how to set these up. I found the libusbK driver to work better than the one he chooses to install, but your mileage may vary.

This USBasp is very well manufactured but it doesn’t work right out of the box for all applications. It needs two additional jumpers soldered on in order to select a lower clock speed for certain target boards., and for resetting the EEPROM chip so that its firmware can be updated. Without these modifications (for which I just had to order the required parts) it triggers error messages in the Arduino board manager software. So it will be a long process before this simple part is able to perform its job. Needless to say it took of course substantial time to test and research everything,

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.

These are really nice for programming microchips (for me ATMEGAs and ATTINYs) without having to put the ArduinoISP sketch on the Arduino, upload the code to the microchip, then upload a new program to the Arduino. I am not sure if this is normally the case with USBASPs, but this one does not show up as a serial port on Arduino. The Arduino IDE still uploads to it just fine. However, if there is a connection issue between the USBASP and the microchip, the Arduino IDE will say that there is nothing plugged into my computer. If I use an Arduino as a programmer instead, I get en error like "avrdude: yikes! Invalid device signature: 0xFFFF [or 0x0000]".

Junk Doesn’t work tech-support was no help said they would call me back but never did waste of time and money never buying again from the seller bad experience

USBASP già aggiornato alla più recente versione di firmware. Impiegato con AVRDUDENESS e AVRDUDE, non è stato necessario installare alcun driver particolare sotto WINDOWS 10. Consigliato sia per "riflashare" Arduino, sia per programmare AVR in applicazioni dedicate, senza la necessità di ricorrere alla scheda di sviluppo e risparmiando eventualmente l'area di flash memory normalmente impiegata per il loader.

Envio muy rapido. Los programadores bien trabajados. Win 10 los reconoce pero hay que actualizar el driver y el firmware.

Yes, the firmware is ancient. However, even with the old firmware it was possible to program an Arduino Nano plug and play using the Arduino IDE in Linux. The serial port does not show up in the IDE but the avrdude software connected and uploaded the project file. No USB driver installation required. Updating the firmware is easy in the Linux environment following the instructions available online.

Wie schon viele andere geschrieben haben, ist die Firmware nicht auf dem letzten Stand und es ist keine Anleitung dabei, was das Update angeht und leider hat es hier auch sonst niemand geschrieben. Man findet dann raus, daß man nach USBASP und Firmware googlen muß, findet "fischl", stellt fest, daß man den J2-Jumper selbst nachbestücken muß, lädt sich von fischl das Hex-file und liest sich in AvrDude ein, fragt sich kurz, welchen Prozessor-Code man braucht (bei mir für diese Programmierer m8) und presto: avrdude -P usb -c usbasp -p m8 -e -U flash:w:usbasp.atmega8.2011-05-28.hex Das Vorgenannte funktioniert für Linux. Unter Windows könnte das Port-Argument (-P) anders aussehen. Dann will man mit seinen eigenen Platinen weitermachen. Also, generell geht es. Vermutllich kann man es nicht der hier gekauften Hardware anlasten, daß AvrDude im Zweifelsfall blind mit zu hoher Geschwindigkeit arbeitet und einfach nichts erkennt, außer man sagt ihm extra, daß er langsamer machen soll. Also beispielsweise: avrdude -P usb -c usbasp -p m168pb -B 10 -t wobei "-B 10" sagt, daß ein 10µs-Takt zu nehmen ist. Ohne diesen Parameter wurde mein mit internen 8 MHz laufender ATmega 328PB nicht erkannt. Was ich außer der alten Firmware und nicht vorhandenen Doku kritisiere, ist die nicht so tolle Qualität. Die Platinen sind teilweise dick mit Flußmittel (?) verkrustet und bei mir läuft nur eine von beiden stabil, die andere wird oft am USB gar nicht erst erkannt. Ein weiterer Kritikpunkt sind die viel zu fest sitzenden Steckverbinder. Das ist grenzwertig. Reinzu und auch rauszu. Last not least: Die Kabel sind falschrum durch die Zugentlastung geführt. Dadurch will das Kabel immer in Richtung USB-Stecker, d.h. quer über die Tastatur des Notebooks. Sehr nervig, wenn die eigene Hardware nur paar Gramm wiegt und das Notebook ein Metallgehäuse hat. Das kann leicht nen Kurzschluß geben. Ach ja .. Im Original sind es eine rote und eine grüne LED, hier sind es zwei winzige rote dicht beieinander, d.h. man kann nicht so leicht erkennen, was da gerade leuchtet. Aber es ist ein preiswertes Angebot, keine Frage.

Per windows 11 dovrete installare dei driver che trovate sul web È necessario installare il driver utilizzando ZADIG (zadig.akeo.ie/). Ho dovuto usare il driver 'LibUSBK (v3.1.0.0) 'per lavorare su Windows 11.
