PCIe TO M.2 HAT+
| ||
Overview
Introduction
PCIe to M.2 M key adapter board for Raspberry Pi 5, compatible with M.2 solid state drive in 2230 / 2242 size, supports Gen2 and Gen3 modes, supports booting PI5 from SSD.
Features
- Support NVMe protocol and M.2 solid state drive protocol, high-speed read/write, with high work efficiency.
- PCI-E×1 Gen2 or Gen3 mode.
- Only supports PI5B.
- Compatible with M.2 solid state drive of 2230/2242 sizes.
- Onboard working indicator lights, with PWR on continuously when powered, and ACT blinking during read/write, making the operating status clear at a glance.
- HAT+ design, with on-board EEPROM chip.
- Onboard power monitoring chip, for real-time monitoring of the working status of the solid state drive.
- Reserved airflow vent for PI5 fans, increasing airflow, and reducing solid-state temperatures.
Note
- Raspberry PI does not support NVME startup by default. Therefore, you need to modify the boot.

Hardware Connection
Pay attention to the direction of the cable and connect it as shown in the figure:
Load
1: Enable PCIe Interface:
The PCIe interface is not enabled by default on PI5B. To enable it, add the following configuration in /boot/firmware/config.txt: dtparam=pciex1
2: PCIE is gen2 by default, if you need to enable PCIE gen3, add it in /boot/firmware/config.txt:
dtparam=pciex1_gen=3
3: After modifying it and restarting PI5, you can recognize the device.
As shown below, the identified SM2263 is my SSD, and the other PI5 is the RPI chip.
4: Note that skip this step if you have partitioned and formatted on other platforms (will delete all data from the SSD and proceed with caution).
lsblk for viewing the disk (If you want to see the details run sudo fdisk -l)
Partition
sudo fdisk /dev/nvme0n1 The device number is the total device number, don't add p1, that's just one partition
How to use fdisk partition tool
n New Partition
q Exit without saving
p Print partition table
m Print selection menu
d Delete Partition
w Save to exit
t Modify ID number
Execute n to add the partition, at last execute w to save and exit.
5: Format:
sudo mkfs. Then press the tab to see a variety of different suffixes, the different suffixes are the formats you need to format.If I want to format to the ext4 file format, execute the following command: sudo mkfs.ext4 /dev/nvme0n1p1 Wait for a few moments, when done has appeared, it means that the formatting has been carried out.
6: Mount:
Create Mount Directory sudo mkdir toshiba Mount the device sudo mount /dev/nvme0n1p1 ./toshiba Checking disk status df -h
Read/Write Test
Enter the directory where the disk is mounted:
cd toshiba
- Release memory:
sudo sh -c "sync && echo 3 > /proc/sys/vm/drop_caches"
- Copying the contents of the Raspberry Pi's memory to the hard drive (Write):
sudo dd if=/dev/zero of=./test_write count=2000 bs=1024k
- Copying the contents of the hard drive to the Raspberry Pi's memory (/etc/fstab read):
sudo dd if=./test_write of=/dev/null count=2000 bs=1024k
- Note: Different cards and environments make different test results. As the Raspberry Pi is more vulnerable to being affected, if you want to test the exact performance, you can use a PC to test.
Auto-mounting
If the testing is sound and you don't need it as a system disk and only use an extended disk, you can set up an automatic mounting.
sudo nano /etc/fstab #Add the following content at the end: /dev/nvme0n1p1 /home/pi/toshiba ext4 defaults 0 0 #/dev/nvme0n1p1 is the device name, /home/pi/toshiba is the directory to be mounted, ext4 is the file system type, defaults are using the default mounting setting #Make the changes take effect (make sure test without problems before rebooting, otherwise it will lead to failure to mount or boot) sudo mount -a #And then reboot Check the device through "lsblk"
NVMe SSD Booting
Start the Raspberry Pi using the SD card, mount, and test to ensure that the hardware is functioning properly.
We provide two methods for you, you can select one to operate:
Method 1
1: Execute:
sudo raspi-config
2: Reboot the Raspberry Pi:
If you find that you can't modify the file several times, please connect to the network and modify it again (wait for the network time synchronization), or set the correct time before modifying the file.
3: Flash the system into NVME, then connect the NVME to the expansion board, remove the SD card and re-power on.
Method 2
1: Start the Raspberry Pi using the SD card and modify the BOOT_ORDER in the Raspberry Pi's bootloader configuration.
sudo rpi-eeprom-config --edit Modify BOOT_ORDER=0xf41 as BOOT_ORDER=0xf416For details, please refer to BOOT_ORDER
2: Reboot the Raspberry Pi:
If you find that you can't modify the file several times, please connect to the network before modifying the file (wait for the network to time itself), or set the correct time before modifying the file.
3: Just program the system into NVME, then connect it to the expansion board, remove the SD card, and re-power it up.
NVME Power Monitoring
The onboard INA219 chip can detect the voltage and current, easy to monitor the device status and monitor the input 5V voltage status (not 3.3V).
The default I2C address is 0x40, addresses can be modified via back resistors to support stacking of different expansion boards.

FAQ
As the Raspberry Pi only supports PCIE gen3 x1 at most, the maximum speed should be 8Gbps.
The maximum test speed should not exceed 1G/s.
In fact, the maximum speed of the test can only be 900M/s.
NO MATTER HOW STRONG YOUR NVME IS, THE BOTTLENECK IS LIMITED HERE.
