3pi device signature = 0x000000

my 3pi was fine just try loading a project avrdude with usbtiny as usual and the response was

C: \ Users \ User> avrdude-p m328p-c usbtiny-F

avrdude: initialization failed, rc = -1
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
avrdude: Expected signature for ATMEGA328P is 1E 95 0F

avrdude done. Thank you.

progamador try another and I could not if anyone can help me thanks


I am sorry you are having problems programming your 3pi. It sounds like the 3pi was not powered during programming. If powering it on does not help, could you try replacing the batteries? If you still have problems, could you tell me more about your setup? Are you using AVRDUDE through a terminal program or are you using a piece of software that runs AVRDUDE?

batteries are not … I charge them and medi … but normally use arduino tanbien try from cmd and also with avrdude wizard, but still the same I think the micro damage

I still suspect the device is not being powered correctly when you are trying to program it. Could you try measuring across Vcc and GND of the 3pi and programmer with a voltmeter to see if they are getting powered correctly when programming?

Sure is not voltage, the microcontroller damage

I am not sure what you meant with your last post. Did you measure Vcc? If so, what voltage did you read?
