Quadruple PCIe HAT for RPi5

The 52Pi B14 Quad FPC PCIe HAT is a powerful expansion board designed specifically for the Raspberry Pi 5. This HAT converts the Pi 5’s single PCIe FPC interface into four independent PCIe connections, making it possible to connect multiple PCIe devices such as SSDs, GPUs, network cards, or other high-speed expansion modules directly to the Raspberry Pi 5.

The board connects easily via the 40-pin GPIO header and supports daisy chaining, allowing multiple B14 units to be linked in series for even greater expansion. With its robust design and included cables and mounting hardware, this HAT is ideal for both developers and advanced hobbyists looking to maximize the potential of their Raspberry Pi 5.

⚠️ Please note: the official Raspberry Pi AI HAT (with Hailo-8L NPU) is not compatible with this product. For the AI HAT it is recommended to use a direct connection via the official M.2 HAT+ or an FPC-to-M.2 adapter.
