The Raspberry Pi M.2 HAT+ (Compact) is an alternative to the existing M.2 HAT+, designed to fit inside the Raspberry Pi Case for Raspberry Pi 5 due to a smaller form factor. The M.2 HAT+ (Compact) supports 2230 form factor NVME SSD drives only. It connects to the PCIe FPC connector on Raspberry Pi 5 via a “flex/rigid” FPC built into the HAT+ PCB.The Raspberry Pi M.2 HAT+ enables you to connect M.2 peripherals such as 2230 form NVMe drives to Raspberry Pi 5’s PCIe 2.0 interface, supporting fast (up to 450MB/s) data transfer to and from NVMe drives and other PCIe accessories.
