M.2 NVME M-key & PoE+ Hat for RPi 5

EP-0241-1.jpg

Descriptions

The M.2 NVME M-key & PoE+ Hat for Raspberry Pi 5 is an innovative accessory that significantly expands the capabilities of the Raspberry Pi 5. Designed with versatility in mind, this PoE+ (Power over Ethernet) Hat allows for a streamlined setup by enabling the Raspberry Pi to draw power directly from an Ethernet port through the use of a PoE switch or PoE power supply. This eliminates the need for a separate power supply and simplifies the overall system architecture.

Features

  • Power over Ethernet (PoE+) Capability: Streamlines the power supply setup by allowing the Raspberry Pi 5 to be powered through the Ethernet port.
  • 5.1V/4.5A Output: Ensures that the Raspberry Pi 5 and any connected peripherals receive adequate power for optimal performance.
  • Compatibility: Specifically designed for the Raspberry Pi 5, ensuring a seamless integration with the device.
  • Safety Warning: A clear note to avoid connecting a power supply to the USB-C port when using the PoE+ Hat to prevent potential device damage.

Specifications

  • PoE type: PoE+
  • Interface: M.2 NVME M-key
  • SSD size: 2230/2242/2260/2280
  • Power Input: Ethernet (PoE+) 802.3at protocol, upto 25.5w
  • Output Voltage: 5.1V
  • Output Current: 4.5A
  • Compatibility: Raspberry Pi 5
  • Safety: Do not connect power supply to USB-C port when PoE+ Hat is in use.

Prepare for the PoE hat

  • The bootloader needs to be configured explicitly to ensure the hardware recognizes that there’s a high-amp PSU plugged in.
  • Open a ternimal on desktop and execute following command:
sudo rpi-eeprom-config --edit

adding following line:

PSU_MAX_CURRENT=5000

Save it and reboot your Raspberry Pi. Tips: Thanks Jose M Paez's tips.

How to enable PCIe on Raspberry Pi 5?

  • Modify /boot/firmware/config.txt and adding following parameters:
dtparam=pciex1

And the connection is certified for Gen 2.0 speed (5 GT/sec), but you can force it to Gen 3.0 (10 GT/sec) if you add the following line after:

dtparam=pciex1_gen=3

You can run devices at PCIe Gen 3.0 speeds if you test and they run stable.

  • Enable auto detection PCIe and booting from NVME.
sudo rpi-eeprom-config --edit

Adding following parts:

PCIE_PROBE=1
BOOT_ORDER=0xf416

The 6 means to enable booting from nvme. Reboot Raspberry Pi 5 and try to use `lsblk` or `lspci -vvv` to get more details of the PCIe device.

  • Partioning and formatting
sudo lsblk

Find out the deivce name like: `/dev/nvme0n1` Partitioning by executing following commands:

sudo fdisk /dev/nvme0n1

and then input:

> p
> n
> p
> 1
> Enter
> Enter
> w
> q
* Format the partition
<pre>
sudo mkfs.ext4 /dev/nmve0n1p1
  • Create mounting point and mounting the partion to the mounting point.
mkdir ~/mydata
sudo mount -t ext4 /dev/nvme0n1p1 /home/pi/mydata -v
  • Automount configuration， edit /etc/fstab file and adding following parameters:
sudo vim.tiny /etc/fstab

adding:

/dev/nvme0n1p1     /home/pi/mydata   ext4   defaults,noatime   0  0

Save it and test it:

sudo mount -a
df -Th

check if the disk has been mounted on /home/pi/mydata location, if not, plesae check if the parameter is correct, do not reboot raspberry pi right now. it may crash the OS.
