ATMega 328 chip in Arduino Uno

Post by SProject »

I am involved in a project and I wanted to know if the ATMega 328 chip in the Arduino Uno can be taken in and out? The Arduino Uno would be used to program the ATMega 328 and then taken out of the Arduino Uno to be put in a separate circuit. If any programming changes would be made then I could put the chip back in the Arduino Uno to modify the program in the ATMega 328. So would I be able to do this?

yes, but not infinitely. IC sockets have a specification for the number of insertions they are supposed to withstand before they lose reliability, and it's a pretty low number. That's not counting the likelyhood of accidentally bending pins or similar during insertion or removal...

You'd probably be better off adding a 6-pin ISP connector to your other circuit. Then you can use a programmer like the AVR ISP mkII or USB TinyISP, or you can even use the Uno as a programmer.
