I'll be posting a video on my YouTube channel about all the new disk options on the Compute Module 4, so be sure to subscribe to my channel for that, but I'll talk about performance a little later in this post. if you want to get bleeding-edge performance out of disk storage, pop in an NVMe adapter with an NVMe, and enjoy the fastest disk IO ever-at least on a Raspberry Pi: For example, if you just want to have a couple USB 3.0 ports like you would on a model B, you can plug in an adapter like the Syba USB 3.1 PCI express card I used: You get this nice PCIe port on the IO board, and you can plug in any PCIe device, as long as it only uses 'one lane' of capacity. I remember earlier this year, Eben Upton mentioned in a podcast that the Raspberry Pi would someday have its PCIe 1x interface exposed directly. The only thing lacking is built-in USB 3.0 ports, and that's one of the differences that made me do a double-take. This board turns your Compute Module 4 into a Pi 4 on steroids, because it has all the ports on a standard model B Pi and then some. The most expensive, creme-de-la-creme version, with WiFi, Bluetooth, 8 GB of RAM, and 32 GB of faster eMMC storage, costs $90.īut to use the Compute Module 4, you will either need to build your own board to integrate it, or buy the Pi Foundation's new Compute Module 4 IO Board, which is an extra $35. The cheapest CM4 is the Lite version with 1 GB of RAM, no wireless, and no onboard storage, and that'll run just $25. You can find all the details on the Raspberry Pi website, but here are the highlights: More Options: There are now thirty two different Compute Module flavors to choose from, whether you want onboard WiFi or not, whether you want eMMC storage, or whether you want 1, 2, 4, or even eight gigabytes of RAM!.What's that? Oh yes, there's now a version of the Compute Module with Bluetooth and WiFi! WiFi and U.FL: It has an external antenna connector for its wireless interface.PCI Express: It drops the USB 3.0 interface for a PCI Express interface, meaning you can do some pretty cool things in lieu of having a couple USB 3.0 ports.Faster eMMC: It has optional onboard eMMC storage, which is now much faster than any microSD card I've tested.But the Compute module has a few other tricks up its sleeve: Instead of the ports, you plug the Compute Module into another board with its special board-to-board connectors. The Compute Module 4 is basically a Raspberry Pi 4 model B, with all the ports cut off. Update: I also did a Live Q&A and Demo Video which has another hour of content going deeper into things I couldn't cover in the review! Compute Module 4 Overview
