Overview

X825 V2.0 is the latest version of X825, updated from X825 V1.5, X825 V1.2 which release at April 1st 2020.

The X825 expansion board provides a complete storage solution for newest Raspberry Pi 4 Model B, it

supports up to 4TB 2.5-inch SATA hard disk drives (HDD) / solid-state drive (SSD). Only 2.5 inch SATA

interface HDD/SDD hard disk is suitable for X825 Board;

You can use X825 V2.0 to DIY your family NAS via RaspNAS or OpenMediaVault etc.

Wiki: https://wiki.geekworm.com/X825_V2.0

Features

1. Supports up to 4TB 2.5-inch SATA hard disk drives (HDD) / solid-state drive (SSD) (Theoretically it can

work with 6TB or 8TB as well. But actually we do not test the X825 board with 6tb or 8tb HDD, you can

have a try.)

2. Ideal storage solution for Raspberry Pi 4 Model B

3. UASP supported by X820 V2.0 for Raspberry Pi 4, NOT support TRIM

4. Use a shorter USB 3 connector to reduce the overall height

5. Use new 4 pieces of test pins to power each other with raspberry pi 4, no additional wire required

6. Blue indicator indicates drive status

7. USB 3.1 Gen1 to SATA 6Gb/s Bridge Controller

8. Since X825 V2.0 use a shorter USB 3 connector, thereby reducing the overall height, so only compatible

with X825-C8 metal case. One X825-C8 case can assembly raspberry pi 4 model b board, X825 V2.0 and

X735.

9. PCB Dimensions: 85x105mm/3.33x4.13inch

About Power

1. You can power the device via DC JACK of X825 V2.0 or TYPE C of Raspberry pi 4 if you don’t use the

X735.

2. Remove the 4-Pin external switch connector in V2.0, please use the X735 to get the safe software

shutdown & PWM fan control function(only X735 V2.5), and removes the on-board button switch also.

3. X825 V2.0 use a shorter USB 3 connector, thereby reducing the overall height, so only compatible with

X825-C8 case. X825-C8 compatible with Pi 4 & X825 V2.0& X735. The X825-C6 or X825-C7 case only

support X825 V1.5.

4. USB 3.0 high-speed transmission will interfere with the Raspberry Pi's 2.4G WIFI signal,if you find the

2.4G signal is unstable, please try to use Ethernet or WIFI 5G AP. (Please refer to:

https://wiki.geekworm.com/X825#Document)

Power Supply Requirement

Power supply: 5Vdc +/-5% , 4A; DC jack - 5.5x2.5mm

1. When use the X825 V2.0 with X735/X708 and Raspberry Pi 4, you power via DC jack or Type-C or

Micro USB of X735 board.

2. When use the X825 V2.0 with Raspberry Pi 4 only, you can power ①Via DC Jack of X825 V2.0②Via

Type-C port of Raspberry Pi 4.

Note: Please use high quality power supply.

DC 5525 Jack

A: Only Raspberry Pi 4+X825 V2.0

Only power the DC Jack of X825 V2.0;

Only power the Type-C port of Raspberry pi 4;

When use the X825 V2.0 with Raspberry Pi 4 only, you can power

①Via DC Jack of X825 V2.0②Via Type-C port of Raspberry Pi 4.

This is a very easy set up, use new 4 pieces of test pins to power each other with raspberry pi 4, no

additional wire required. But not support use external power control switch.

B: Raspberry Pi 4+ X825 V2.0+ X735

When use the X825 V2.0 with X735 and Raspberry Pi 4, you power via DC jack or Type-C or Micro USB of

X735 board. Recommend power via DC jack or Type-C.

This kit use the X735 for safe shutdown and cooling function, and X735 V2.5 use the PMW cooling fan

controlled by script, and also support use external power switch.

C: Raspberry Pi 4+ X825 V2.0+ X708 (no match metal case)

This kit use the X708 for UPS, safe shutdown and cooling function, also support use external power switch,

BUT no match case for this kit.

D: Raspberry Pi 4+ X825 V2.0+ X735+X825-C8 (Recommend)

This is a complete NAS kit with power management and heat dissipation solution, also with a metal case to

install the whole kit to protect the kit.

Matching Metal Case (X825-C8)

WiKi for reference: https://wiki.geekworm.com/X825-C8

X825-C8 metal case with power control switch and 4010 cooling fan is designed for Raspberry Pi 4 Model B

with the latest X825 V2.0 2.5 inch SATA HDD/SSD storage board, also support the X735 safe shutdown

cooling fan board over Raspberry Pi 4.

1. Only support Max 9.5MM thickness capacity 2.5 inch SATA HDD/SSD(Do not support 15mm thickness

2.5 inch SATA HDD/SSD)

2. Support install the X735 power management board to use external power switch

3. Not support X708 UPS with battery holder installation

FAQ

Q1: Why system crashes while using USB Boot, and shows drive was removed?

A: Please try to format the HDD/SSD especially when using a new HDD/SSD.

When you find that HDD/SSD is not recognized, please also try formatting the HDD/SSD to check.

Q2: Don't detect HDD/SDD?

A: This is a complicated question, but we can check it from these points. Please refer to How to check the

X825.

The power supply is very important to X825, some low quality power supply will damage your board or not

recognize the HDD/SDD.

Q3: Do I need an external power source supplying for X825 board?

1. When use the X825 V2.0 with X735 and Raspberry Pi 4, you power via DC jack or Type-C or Micro USB of

X735 board. Recommend DC jack or Type-C.

2. When use the X825 V2.0 with Raspberry Pi 4 only, you can power ①Via DC Jack of X825 V2.0②Via

Type-C port of Raspberry Pi 4.

Q4: Does the X825 support USB boot?

A: Please refer to Does the X825/X855 support USB boot.

Q5: Why X825 cannot recognize the HDD when doing big data transfer?

A: This situation do not related with the hardware, please try to check and update the firmware. We have

test continuous copy of data that has exceeded 15GB in windows.

Q6: What is the polarity of the X825 DC 5V in port ?
