I had to know more, so I asked Gordon Hollingworth about the design, and he referred me to Simon Martin, who was principle designer of this chip.
and in a place where vanishingly few people will ever notice! I love seeing little design details like this, since it reminds me of the signatures inside the Macintosh case-a little mark of pride from the hardware designer that also shows a spirit of playfulness. So Raspberry Pi decided to make their own, and put it all inside one easier-to-mass-produce chip.īut I was looking through more angles via digital X-ray when something else caught my eye:ĭo you see that little pattern in the middle of the BGA ('Ball Grid Array') on the main chip? Does it remind you of anything? How about we zoom and enhance:Īnd there it is! I stuck a transparent Pi logo on there in case it's still hard to see. Older Pi Zero models (and some of the older Pi A/B models) used a package-on-package layout, but the BCM2710 used here didn't come in a variety that was stackable. So this is not custom silicon, but it is a custom 'package'. You can distinctly see two sets of bond wires-in this case, gold bond wires, as indicated by the -AU chip suffix-with one leading to the 512MB LPDDR2 RAM on top, and the other leading to the BCM2710A1 clocked at 1 GHz on the bottom.
1x microSD card reader for boot volumes.1x mini CSI connector on edge for Pi Camera modules.This board has the exact same physical layout as the earlier Pi Zero W, with the same I/O, meaning it will fit in almost every accessory and project designed for earlier Pi Zero models. You might already see a few of the easter eggs hidden inside, but let's first get the basics out of the way. Also, I paid a bit of money to get these pictures, so might as well share!įirst, here's what the Zero 2 W looks like in person: I was able to get early access to the Zero 2, and I have a full review of the device on my YouTube channel, but I wanted to share more of the X-ray images I took of the device to reveal its inner workings, and because I just think they look cool. Today, Raspberry Pi released their new Zero 2 W, and it includes a new Raspberry Pi-branded chip, labeled RP3A0-AU.
