How to Power X882 V1.3&Pi4
Contents
Overview
This is an ultra-compact raspberry pi 4 dual 2.5 inch sata hdd/ssd storage board X882, it allows two 2.5" HDD/SSD to working at the same time with your Raspberry Pi 4. The SuperSpeed USB 3.0 port delivers a blistering data transfer rate of up to 5Gbps, letting you transfer a large amount of data in seconds.
X882 is not sold seperately, we have designed a case for X882 and sold it as a set, please refer to NASPi Gemini
Update History:
In December 2022, the X882 V1.3 has been updated to X882 V2.0, remove the USB-C port on X882 V1.3, and update DC 5V power in to wide voltage input DC6-18V power in.
The new version completely solve the issue of I/O error.

SPECIFICATION
Power supply: 5.1Vdc +/-5% , ≥4A(For X882 V1.3 Version)
Power supply: 6-18Vdc +/-5% , ≥4A(For X882 V2.0 Version)
Ports & Connectors:
DC jack - 5.5x2.1mm (DC5525 Jack is compatible with DC5521, you can also use the PSU with DC5525 Jack)
Type-C port(Geekworm Type-C 5V 4A 20W power supply is recommended.)
USB socket - USB 3.0 type A
Power connector - 5V Out XH2.54 2-pin
PWM Fan port 3-pin

Power Supply Requirement
Please use high quality power adapter, or the HDD/SSD may cannot be recognized.
Since X882 can install two 2.5-inch hard drives, it needs a high-quality power supply to provide enough current.
NOTES
Due to installation restrictions, please pay attention to the thickness of 2.5" SSD/HDD.
We do not recommend using Samsung hard drives,Please use hard drives of other brands.
As with all SSDs, new SSD/HDD must be formatted before use.
Older SSD drives with less efficient flash media may not perform as well as newer drives.
A microSD card is required for forceing the Raspbian OS to use the HDD/SSD for its "root" partition
Additional USB3.0 A Male to A Male cable is required (not supplied)
Do not power your Raspberry Pi via the Pi's 40-pin header and Type-C USB socket at the same time.
Hello, after the Raspberry Pi 5 is released, we will also upgrade the product. Please follow us. If you have good suggestions, we are also willing to listen.
I've got the version 1.3. I tried several settings but always got troubles when i try to upload a large amount of files: the SSD are disconnecting.
When i tried using seafile, this issue corrupted the database and i lost all the data. Now i'm only using Samba and at least the issue only stop the current upload and don't destroy previous data.
My question is: may it be related to the DC 5V power supply? I'm using a 5V10A supply, but maybe something is limited on the board?
Some precision: when I said "SSD are disconnecting": the Pi works well, and i got a message on raspbian specifying that the disks unmounted. when I reboot the pi, the drives are mounted back.
Hello, the problem you are talking about may be caused by the power supply, because dual hard drives have relatively high power requirements. The initial version 1.3 used a 5V 4A power input. Later we upgraded to version 2.0, which used a 12V 5A power input. Power supply, the current version 2.0 has solved the problem of insufficient power supply (tip: version 1.3 cannot be directly connected to 12V, because it will burn the board)
Thank you for your answer. You may understand that i'm not really keen to buy another board, and the 1.3 is not usable as it is whith this power input problem.
On the 2.0, there seems to be components around the DC input that may be used to regulate the power from the 6-18V jack to the components requirements.
I may be able to "replicate" this part of the board, but for this what would be the output specifications?
Are the SSD still powered with 5V on within the 2.0 board?
1. First of all, x882 v2.0 cannot use 5V input, because dual hard drives usually require relatively large voltages, and 5V will cause insufficient power supply.
2. your mean by ‘replicate’ may not be able to solve this problem. This is more complicated.
We have reported the problem you previously reported to the manufacturer. In addition to the problem you mentioned may be caused by insufficient power supply of the V1.3 version (when transferring large files), there is another possibility that the SSD EMC interference is relatively large, so you You can try using an HDD to see if the problem still exists.
Yes, I understand that you cannot input 5V on the 2.0 board, that was not my question.
You are basically telling me that after buying a 50$ V1.3 board that is not working as intended (plus a power supply, shipping and taxes), I should either buy new HDDs or a new 2.0 board.
I'm not really thrilled by this idea, and my goal was to know if there was a way to modify the 1.3 board to help solve the issue (I have access to some equipment and could for exemple build a power supply). I understand that this may not be possible, and even that if it is possible it would not be easy nor guaranteed to work.
But the other possibilities for me would be to either buy a 2.0 board (with no guarantee that it would be better) or some HDD (for lower performance, but i could allow that, but again how to be sure that this investment would solve the issue?), or drop the project altogether.
Hello, have you tried HDD? The problem you mentioned may also be caused by SSD EMC interference is relatively large, not necessarily caused by the power supply.
Hi...
Did anyone try to boot a Pi from SSD / HDD with this x882 board with just ONE drive attached?
In this case my Pi do just NOTHING only if i attach a second drive to the board (no matter if there is something saved on the drive or not - just the hardware) the Pi will boot properly.
Let me introduce you roughly, RAID mode (PM/RAID 0/RAID 1/SPAN), when choosing one of the RAID modes, you need short or open A/B, you can choose one of the RAID modes, 1 .Short A&B (RAID 0) at the same time, or 2.open A and short B(RAID 1),3.open B and short A(SPAN),4.open A and B(PM) at the same time, hope it can help you, If you still don’t understand, you can send question to our email. Please contact us at support@geekworm.com. We will explain in more detail and solve the problem for you
