Once removed rather than replace the IC which would have been difficult to resolder, I bridged a piece of wire between the bottom right corner pad of the inductor, an the positive terminal of the large tantalum capacitor as shown below. I can’t think of any reason for it to get hot unless it has somehow become partially shorted. The device that ‘gets very hot’ appears to be a 6MHz crystal or ceramic resonator clock for the USB interface chip. In the end I chipped away all of the epoxy of the IC to get down to the metal lead-frame allowing me to get the soldering iron in to heat it. Fortunately I was able to fix it my one I bought it in clearance so couldn’t return, hence having nothing to lose trying to fix it. Test uw instellingen op de volgende website:

Avrisp mk2 usb All ICs stay cold though. Test uw instellingen op de volgende website: Testen Sie Ihre Einstellungen unter: The cathode connects to my jumper. Remove it and put a 6MHz crystal in its place.
While I was at it, I also added a 1N diode and 2. When the jumper is removed the behaviour is as standard with the target device being self powered and avrisp mk2 usb the IO voltage. Post as a kk2 Name. I have measured the voltage levels on these traces, it avrisp mk2 usb as if something was wrong with the power supply as you suspected.

And what might be a likely explanation of this strange death? The device that ‘gets very hot’ appears to be a 6MHz crystal or avrisp mk2 usb resonator clock for the USB interface chip. As suggested by Raj I have measured the avisp levels in what seems to be the power supply section of the device.

Here is a picture of it USB connector on the left, 6-pin programming header on the right: A partire dal avrisp mk2 usb di settembre potranno accedere al sito web di Mouser unicamente i browser che supportano il TLS 1.
I switched the programmer’s USB cable, but that did not help.

And that was all it took. In fact the only thing I can think is if there is a short or dead part somewhere else on the board which is causing excessive current draw hence voltage drop of supply and causing the board to heat up. Here is a picture of it USB connector on the left, 6-pin programming header on the right:. Sign up using Facebook. Avrisp mk2 usb first step was to remove the IC completely. Fortunately I was able to fix it my one Avriso avrisp mk2 usb it in clearance avrisp mk2 usb couldn’t return, hence having nothing to lose trying to fix it.
