Collaborate Disseminate
Last time, we looked over diffpairs, their basics, routing rules and the notorious tolerances of PCIe when it comes to diffpairs. Now, let’s take a look at the exact signals …read more Continue reading PCIe For Hackers: Link Anatomy
PCIe, also known as PCI-Express, is a highly powerful interface. So let’s see what it takes to hack on something that powerful. PCIe is be a bit intimidating at first, …read more Continue reading PCIe For Hackers: The Diffpair Prelude
Many mainboards and laptops these days come with a range of M.2 slots, with only a subset capable of NVME SSDs, and often a stubby one keyed for ‘WiFi’ cards. …read more Continue reading What Else Is An M.2 WiFi Slot Good For?
Recently, we stumbled upon a video by [iBoff], adding an M.2 NVMe port to a 2011-2013 MacBook. Apple laptops never came with proper M.2 ports, especially the A1278 – so …read more Continue reading Macbook Gets NVMe SSD With Help Of A BGA-Imitating PCB
[Jeff Geerling] saw the Raspberry Pi Compute Module 4 and its exposed PCI-Express 1x connection, and just naturally wondered whether he could plug a GPU into that slot and get …read more Continue reading A Real GPU on the Raspberry Pi — Barely.
Did you ever feel like your laptop’s GPU was sub-optimal, or perhaps that your laptop could use a SAS controller? [Rob Rogers] felt like that too, so now he has …read more Continue reading This Laptop Gets All The PCIe Devices
PCI Express (PCIe) has been around since 2003, and in that time it has managed to become the primary data interconnect for not only expansion cards, but also high-speed external devices. What also makes PCIe interesting is that it replaces …read more
Continue reading The Bus That’s Not A Bus: The Joys Of Hacking PCI Express
The history of storage devices is quite literally a race between the medium and the computing power as the bottleneck of preserving billions of ones and zeros stands in the way of computing nirvana. The most recent player is the Non-Volatile Memory Express (NVMe), something of a hybrid of what …read more
Continue reading NVMe Blurs The Lines Between Memory And Storage
Ever since people figured out that the Raspberry Pi 4 has a PCIe bus, the race was on to be the first to connect a regular PCIe expansion card to a Raspberry Pi 4 SBC. Now [Zak Kemble] has created a new approach, using a bridge PCB that replaces the …read more

It probably goes without saying that hardware hackers were excited when the Raspberry Pi 4 was announced, but it wasn’t just because there was a new entry into everyone’s favorite line of Linux SBCs. The new Pi offered a number of compelling hardware upgrades, including an onboard PCI-Express interface. The …read more
