-The Raspberry Pi M.2 HAT+ M Key enables you to connect M.2 peripherals such as NVMe drives and other PCIe accessories to Raspberry Pi 5's PCIe interface.
+The Raspberry Pi M.2 HAT+ M Key and M.2 HAT+ Compact M Key enable you to connect M.2 peripherals such as NVMe drives and other PCIe accessories to Raspberry Pi 5's PCIe interface.
 
-The M.2 HAT+ adapter board converts between the PCIe connector on Raspberry Pi 5 and a single M.2 M key edge connector. You can connect any device that uses the 2230 or 2242 form factors. The M.2 HAT+ can supply up to 3A of power.
+The M.2 HAT+ and M.2 HAT+ Compact adapter boards convert between the PCIe connector on Raspberry Pi 5 and a single M.2 M key edge connector. The M.2 HAT+ supports any device that uses the 2230 or 2242 form factor; the M.2 HAT+ Compact supports any device that uses the 2230 form factor.
 
-The M.2 HAT+ uses Raspberry Pi's https://datasheets.raspberrypi.com/hat/hat-plus-specification.pdf[HAT+ specification], which allows Raspberry Pi OS to automatically detect the HAT+ and any connected devices.
+We provide the M.2 HAT+ in a standard and a compact format to serve different use cases:
 
-The included threaded spacers provide ample room to fit the Raspberry Pi Active Cooler beneath an M.2 HAT+.
+* The M.2 HAT+ includes threaded spacers that provide ample room to fit the Raspberry Pi Active Cooler beneath it.

 == NVMe SSD boot
 
-NVMe (Non-Volatile Memory express) is a standard for external storage access over a PCIe bus. You can connect NVMe drives via the PCIe slot on Compute Module 4 IO Board, the M.2 slot on Compute Module 5 IO Board, and Raspberry Pi 5 using an M.2 HAT+. With some additional configuration, you can boot from an NVMe drive.

With some additional configuration, you can boot from an NVMe drive.
 
 === Prerequisites
 
 ==== Hardware
 
 * NVMe M.2 SSD
 * an adapter to convert from PCIe to an M.2 standard.
-** For Raspberry Pi 5, we recommend the xref:../accessories/m2-hat-plus.adoc[M.2 HAT+], which converts from the Raspberry Pi's *PCIe FFC* slot to an M Key interface.
+** For Raspberry Pi 5, we recommend the xref:../accessories/m2-hat-plus.adoc[M.2 HAT+ or M.2 HAT+ Compact], which converts from the Raspberry Pi's *PCIe FFC* slot to an M Key interface.
 ** For the CM4, search for a "PCI-E 3.0 ×1 lane to M.2 NGFF M-Key SSD NVMe PCI Express adapter card"
 
 To check that your NVMe drive is connected correctly, boot your Raspberry Pi from another storage device (such as an SD card) and run `ls -l /dev/nvme*`. Example output is shown below.
