Atmega328P with 25 Mhz Crystal

Hello everyone!

I got a question, I've been reading about standalone atmega chips recently and I was wondering if it's possible to use a 25Mhz crystal instead of a 16Mhz because that's all I've got laying around at the moment and I can't wait for a shipment because I'm so excited to start with my project!

Info that might help:
I have an Arduino UNO and it's chip (got more 328P's arriving next week) and a USB/TTL PL2303 adapter with +5V, GND, RXD, TXD and 3V3.

It is possible but don't try it unless you are sure what are you trying to do.

Why you want that chip standalone ??
If you want to try that, You can use the crystal on the board by removing the m328p amd poking wires in the DIP socket in XTAL1 and XTAL2 pins

I want the chip standalone because I'm going to build a weather station with the DHT11 and a 4 character 8Bit display and I don't want to put the whole arduino in it, I'd like to use the arduino for other things when the other chips arrive. I also ordered some chinese nano's but they won't arrive untill 18 days from now.

You can go to local electronics store and ask for 16MHz crystals. They cost ~$0.08/piece. The atmega 328 chip is rated at only 20MHz. You can't run it at 25MHz and wish that it will work perfectly.

Problem with that is that I live in the middle of nowhere and shipping takes ages to arrive so I try to salvage parts as much as possible

Sad! Here is something which may help you out-https://www.avrprogrammers.com/howto/max-speed

I found a 16Mhz crystal in an old wireless mouse! Hope it works! Thanks for all the answers people!

Got it working. Here’s a link for everyone who wants to see it. It’s currently using the Blink sketch to test it:

Congrats, Happy to see it running.
We sometimes do some JunkBin diving to get the required part. As I did HERE.(Second post);
