I remember meeting up with the founders of BitScope and we were on our way to see Eben Upton, wondering what we could do with all the Raspberry Pi Zeros that we had in our collections. What do we do with all these slow RPi Zeros?Ī stack of the original Raspberry Pi Zeros I'm going to give you a quick refresher on what they do well, before getting hands on with the newer version and answering the questions that I know you have. That lead me to ask the question of what to do with my original Raspberry Pi Zeros. Over time, many open source projects (including OpenFaaS that I maintain) dropped support for its ARMv6 processor due to its slow speed and issues in the ecosystem. This meant that the Raspberry Pi was often last picked for new projects, especially when I wanted to use infrastructure projects. Yes there are a lot of variations of the Raspberry Pi, so where does this fit?Īs I mentioned, running Node.js used to take several seconds to launch, and compiling Go programs could take minutes, where as on a Raspberry Pi 4 these tasks would complete much quicker. Unfortunately the team were unable to upgrade the RAM to 1GB, which would have made this a smaller Raspberry Pi 3. The exact performance uplift over Zero varies across workloads, but for multi-threaded sysbench it is almost exactly five times faster. Priced at $15, Raspberry Pi Zero 2 W uses the same Broadcom BCM2710A1 SoC die as the launch version of Raspberry Pi 3, with Arm cores slightly down-clocked to 1GHz, bundled into a single space-saving package alongside 512MB of LPDDR2 SDRAM. The new version has the same processor as the original Raspberry Pi 3. Twinning - on the left, the original and on the right the new Zero 2. It's been several years since I first reviewed the original Raspberry Pi Zero W, so what's changed and what's it good for? Note: this blog post is best viewed on a PC, some images will not show if you're on a mobile device What's new? The original Zero / Zero W had a CPU that was only compatible with armv6 architectures and became quickly underpowered for my Node.js and Go applications. The Raspberry Pi Foundation sent me one of these boards for testing earlier in the year. I've got my faasd t-shirt on and you'll find out why below. Can you run containers? Can you run OpenFaaS? What about K3s? Is it worth buying or will it gather dust? I'm going to share my thoughts and experiences with it. Today the Raspberry Pi Foundation released the Raspberry Pi Zero 2 W.
