PCIe TO M.2 Board (C) for Raspberry Pi 5, compatible with 2230 / 2242 / 2260 / 2280 size M.2 solid state drive, supports Gen2 and Gen3 modes, supports booting PI5 from solid state drive (SSD), side-mounting solution, comes with acrylic mounting plate.


  • Support NVMe protocol M.2 interface solid state drive protocol, high-speed write/read, higher working efficiency.
  • Support PCI-E×1 Gen2 or Gen3 mode.
  • Only support PI5B.
  • Compatible with 2230 / 2242 / 2260 / 2280 size M.2 solid state drive.
  • Onboard working indicator, light-up when powering on, and the ACT status indicator keeps blinking while writing/reading.


  • As Raspberry Pi does not support booting from NVME by default, you need to modify it to realize it.

User Guide

Hardware Connection

Please pay attention to the wiring direction, as shown below:

1: Enable PCIE interface:

PCIE interface is not enabled on the Raspberry Pi 5 by default, you can add the following content to enable it at /boot/firmware/config.txt:

2: PCIE gen2 is the default setting, if you want to enable PCIE gen3, you need to add the following content at /boot/firmware/config.txt:


3: Reboot PI5 after modification, and the device can be recognized.

In the picture below, the SM2263 is recognized as my SSD solid state, and the other PI5 one is the RPI chip.

4: Partitioning: If partitioning and formatting have already been performed on another platform, skip this step. Caution: Partitioning and formatting will erase all data on the SSD, so proceed with caution.

lsblk  #see the disk (execute "sudo fdisk -l" for more details)

sudo fdisk /dev/nvme0n1    #dev is the total device number, do not add "p1", it is just one partition 
How do use fdisk
n New partition
q Exit without saving
p Print partition table 
m Print selection menu  
d Delete partition  
w Save and exit
t Modify ID 
Add the partition and execute "n", and then press "w" to save and exit. 

5: Format.

sudo mkfs.  #Then, pressing Tab will display various file extensions. Each extension corresponds to a format you may want to format the drive into

If I need to format it in "ext4" format, execute:  
sudo mkfs.ext4 /dev/nvme0n1p1
Wait for a moment, when "done" appears for all, it means the formatting is complete.

6: Mount.

Create the mounting directory:
sudo mkdir toshiba
Mount the device
sudo mount /dev/nvme0n1p1 ./toshiba
Check disk status
df -h

Read/Write Test

Enter the directory to mount the disk.

cd toshiba
  • Release the caches.
sudo sh -c "sync && echo 3 > /proc/sys/vm/drop_caches"
  • Copy the Raspberry Pi memory to the hard flash driver (write).
sudo dd if=/dev/zero of=./test_write count=2000 bs=1024k

  • Copy 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 may significantly different affect Raspberry Pi's performance, so for accurate performance testing, it's recommended to use a PC.

Auto Mount

If there are no issues with the test and the disk is not needed as a system disk, only for expanding disk usage, set up automatic mounting.

sudo nano /etc/fstab

#Add the following content at the end:
/dev/nvme0n1p1  /home/pi/toshiba  ext4  defaults  0  0
#/dev/nvme0n1p1 device name, /home/pi/toshiba mount to the directory, ext4 is the file system type, defaults means using the default mounting options  
#Reboot to take effect (Please make sure there are no issues before rebooting, otherwise it can not be booted without mounting)  
sudo mount -a

#And then reboot
Check the device through lsblk 

Booting from NVMe SSD

1: First, you can use an SD card to boot the Raspberry Pi, just test it to make sure the hardware can work properly.

2: Use the SD card to boot the Raspberry Pi and modify the config file, modify BOOT_ORDER:

sudo rpi-eeprom-config --edit 
Modify BOOT_ORDER=0xf41 as BOOT_ORDER=0xf416

For more details, you can refer to BOOT_ORDER 

3: Reboot the Raspberry Pi, and you can see the following content in serial port log during start-up:

That means the modification is successful. 
If you fail after trying several times, you can connect it to the network before modify again (wait for network time synchronization), or set the correct time before modifying the file.

4: Flash the system to NVME, and then connect to the board, remove the SD card, and power it on again.
