Topic: Uno R3 board - remove chip on the board to be used permanently on a project? (Read 2228 times) previous topic - next topic

Hello,

apologies if this has been asked before, but I can not seem to find an answer, or at least an uncomplicated answer.

First off, I'm using an Elegoo Uno R3 board, as I received it for Christmas, so this is all new to me.

My question is, once I've built a project and the chip has been programmed. Can the chip be removed from the Uno board and permanently be mounted into a project, and placing a new chip onto the Uno board?


Or can I program a new chip to be removed on a blackboard, although I assume that isn't possible.

I was given an Elegoo Uno as mentioned but I'll get the Arduino model to suit if needed.

Cheers

Yes.

Additional info:
To be able to program your new 328P chip, you either need a programmer (an other Arduino can be that programmer) or you can buy the 328P programmed with the bootloader so you can program it via USB.
If you understand an example, use it.
If you don't understand an example, don't use it.

Ah okay. Not sure why I didnt come across this. Blame it on tirdness, rather than stupidity ha.
So this is the badge then...

No idea, the farnell website is down.

An other solution is to make provisions on your board for upload via ICSP and use your elegoo as a programmer. In that case you can use 328P processors that don't have the boot loader.
If you understand an example, use it.
If you don't understand an example, don't use it.

Thank you for throwing ICSP out. That sounds like an option. Will have a read further into that.

Right, ISP is the way to go. But I've just confused myself looking into this. Apologies, this is all new to me, well onther than some basic electronic stuff I did at college years ago.

Turning my board into the programmer to bootload another chip etc. Can the uno board reversed, or will it remain a programming board.

sterretje

I have not used an Uno as a programmer (as I have a dedicated programmer). But to my understanding it's just a sketch that you upload to change it to programmer; after that you can load another sketch again.
If you understand an example, use it.
If you don't understand an example, don't use it.

Thats what I thought at first but then I couldn't anywhere that specified either way.
May I ask what you use as a dedicated programmer?
