00:00Alright, so if you've ever blown up a microcontroller at 2 in the morning because you wired something
00:04backwards, yeah, me too. And that's exactly why I went hunting for the best deals on Atmega AVR
00:10chips out there. These are the brains behind so many Arduino builds, and honestly, you don't need
00:16to be spending 15 bucks a pop at the big retailers. I found 5 listings worth your money, so let's
00:22get
00:22into it. Kicking things off, we've got this multi-variant listing that covers the Atmega
00:28164p, the 164pa, the 324a, 324p, 324pa, and even the classic Atmega 8535. $2.02. That's it.
00:41What I love here is the flexibility, you pick the exact variant you need instead of buying a
00:45whole reel of one part. Nearly 4800 of these sold with a 4.7 rating, which is about as solid
00:52as it
00:52gets on a chip listing. If you're prototyping and you're not sure yet whether you need the low-voltage
00:57version or the standard 20MHz one, this is where I'd start. Cheap enough to buy a couple spares.
01:05Next up, the single-piece Atmega 324pa AU in the QFP package, coming in at a flat $2.
01:12This one's for when you know exactly what you want and you just need one chip, today.
01:16It's the 44-pin TQFP, 32k of flash, and it's a genuinely great sweet spot between the little Atmega
01:23328 everyone starts with and the bigger 1284. The seller lists it as in stock, which matters
01:29more than people realize, I've waited three weeks on backordered chips before and it's miserable.
01:34Four and a half stars over 4,700 sales. Reliable, boring, and that's a compliment.
01:42Third, another take on the Atmega 324pa AU, this time at $2.96.
01:47Now, why pay $0.90 more? Because this listing spells out the exact specs, 32kb, 44-pin TQFP,
01:56QFP44, and when you're ordering surface mount parts, ambiguity is your enemy.
02:01I've had listings arrive with the wrong package before and that's a wasted board.
02:064500 sold, 4.6 rating. If you're doing a small production run and you need consistency across
02:12every board, that extra clarity is worth the pocket change. Buy with confidence, solder with confidence.
02:20Number 4 is the big one, the Atmega 1284p bundle, at 1118. This covers both the AU and MU packages,
02:28plus a whole spread of 324 variants. And look, the 1284p is the chip you graduate to .128k of flash,
02:3616k of RAM, that's 4 times the SRAM of a standard Arduino Mega. If you're building something with a
02:43graphics buffer, a data logger, or a project that keeps running out of memory, this is your answer.
02:48It's the priciest here, but you're paying for real headroom. 4.7 stars, and it's listed as new
02:55original stock, which is the phrase you want to see. And rounding out the list at 959, this one's a
03:01grab
03:01bag, and I mean that in the best way. You've got the Atmega 324pa, the Atmega 644pa with its 64k
03:09of
03:09flash, plus some genuinely random extras like the AK4527 audio codec and a Motorola 68HC908.
03:17Free shipping too. This is a listing for tinkerers, people who just like having parts on the shelf.
03:24The 644pa in particular is a lovely middle ground if the 324 is too small and the 1284 feels like
03:31overkill. 4100 sold, 4.6 stars. Fun listing.
03:38Alright, that's the 5. All the links are down in the description, so go grab whatever fits your build.
