==Overview==
The M901 shield is a NVME M2 SSD PIP (PCIe Peripheral Board) for the Raspberry Pi 5 that uses the new PCIE interface of the Raspberry Pi 5 to utilise the NVME M2 SSDs for fast data transfers and ultra-fast booting.

This shield follows the new "PIP" design guideline from Raspberry Pi fundation ensuring that it will be easy to use and be supported long term by updates to Raspberry Pi OS - though it is very early days and things are improving rapidly there!

==Important Note==
{{NVMe SSD Incompatibility List}}

==Features==
* Minimalist design, easy to install
* Compatible with other HAT shield;
* Supports installation of official active coolers;
* SSD ACT LED Indicators-On: Power OK/Standby, Flashing: Reading/Writing
* Supports 2230/2242/2260/2280 NVME M2 SSD
* Can power the M901 shield directly from the FFC PCIe ribbon (providing maximum 5W of continuous power)

PS:
* Maximum current for pcie connector is 1A, and voltage is 5V
* If you find that the SSD is not working properly, it is possible that the power supply of SSD is not enough, then you need to check the current requirement of your SSD to decide whether power the SSD separately.
* The M901 hardware has no limit on NVME SSD capacity, which is dependent on the Raspberry Pi OS.

==Test Reviews==
By default the PCIe connector is not enabled. To enable it you should add the following option into <span class="tb_blue">/boot/firmware/config.txt</span> and <span class="tb_blue">reboot</span>:
sudo nano /boot/config.txt
Then add the following comment;
# Enable the PCIe External connector.
dtparam=pciex1
# This line is an alias for above (you can use either/or to enable the port).
dtparam=nvme

Press '''Ctrl-O''', then enter, to write the change to the file.

Press '''Ctrl-X''' to exit nano (the editor).

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 also can refer to official documentatio:[https://www.raspberrypi.com/documentation/computers/raspberry-pi-5.html#enabling-pcie Enabling PCIe]

After I forced Gen 3.0 speeds, in my many tests I found that some NVMEs were able to run stably, but some NVMEs caused some problems: such as slow startup and running laggy, really really laggy. As the official statement says:

The Raspberry Pi 5 is not certified for Gen 3.0 speeds, and connections to PCIe devices at these speeds may be unstable.

'''Run the following command on Teminal window to test:'''
dd if=/dev/zero of=./Testingfile bs=100M count=10 oflag=direct
dd if=./Testingfile of=/dev/zero bs=100M count=10 oflag=dsync

'''Nomral PCIE 2.0 test data with''' ''dd'' '''command;'''
