Radxa Quad M.2 SSD HAT #652
Comments
The name would be Radxa Quad M.2 SSD HAT. The USB C on the HAT supports PD power supply to power the 4x SSD and Pi 5(>45W). So the PD negotiation voltage for the sample is 12V, but we will increase to 20V by default in next HW revision, fall back to 12V if the power supply doesn't support 20V. |
You're burying the lede here, the ASM2806 is a PCIe Gen 3 switch! Would be a very cool board for multiple M.2 drives, or a mix of M.2 NVMe SSDs and Hailo AI accelerators :) @hipboi any word on when this might be up for sale? I know a few people were interested in something like this. |
I think it will be available within 4 weeks. |
So now I have my 4 NVME's an started my testing. Connected to the USB C port of the Quad M.2 SSD Hat the system used 10 to 12 watts.
output from dmesg:
With the power supply attached to the Raspberry Pi 5 USB C port all disks are showing up an the power consumption is between 12.5 to 15 watts
output of dmesg:
It seems that the Pi an the Quad HAT don't deliver enough power to use all 4 NMES's |
This Kernel Patch #647 (comment) works perfectly, all drives shown and are available. But for booting from NVME is a EEPROM update necessary.
|
Glad my patch was useful but wanted to send on that there is a dtoverlay already available to do a similar effect that also works that doesn't require patching the kernel. |
Is this available for purchase yet? |
Hi, I'm super interested in this 4xNVME HAT and I'm glad there's a software path to have all drives mountable. |
@coreintelligence It will be available in 4 weeks. |
Awesome! I'll happily treat myself to a nice Christmas/End of Year present for my Pi 5 |
Not to be a downer but you said the same thing 5 months ago. Is there any confirmation on this? And any idea on price? |
I recived a new testing prototype from RADXA with the print RA028_X1.0 (thanks @hipboi )
It's an 4 bay M.2 NVMe Hat that supports 2230, 2242, 2260,2280 NVMe's and is powered by a USB C port at 12 volts (you can use the official Raspberry Pi 5 power supply).
The main chip ist the ASM2806.
More about testing tomorrow!
