==Overview==
This is new updated X857 V2.0 version from [[X857]] V1.2.
<span style="color:red;">'''Some changes:'''</span>
* We removed the DC JACK power socket of X857 V2.0, X857 V2.0 is powered via USB 3.0 connector.
* We use shorter copper spacer to connect Raspberry Pi 4 and X857 V2.0, which reduces the height of the entire product, so the matching metal case [[X857-C3]] is shoter 3mm than [[X857-C1]];
* After our test, X857 V2.0 can connect to 2.4G wifi in seconds without the metal case. However, '''if X857 work with a metal case or external USB 3.0 devices such as a mouse or keyboard, you may still need to use Ethernet or 5G AP.'''
* But if you use a metal shell like [[X857-C3]], then you can only use 5.8G wifi AP, 2.4G wifi will not be available(be shielded by metal case);
* As a Raspberry pi NAS device, we advised that you use ethernet network to replace wifi, this will be more stable and reliable.
* X857 V1.2 version supports TRIM but not UASP, '''V2.0 version supports UASP but not TRIM. '''
* We found that the stability of wifi is related to the brand of SSD.
==Features==
* Ideal storage solution for Raspberry Pi 4 computer - mSATA SSD Shield
* Supports up to 2TB mSATA solid-state drive (SSD)
* '''UASP supported ONLY for X857 V2.0, do not support TRIM'''
* Integrated USB 3.1 Gen1 to SATA 6Gb/s bridge controller
* Integrated high efficiency step-Down Converter, 3.3V max 4A to power the SSD
* Allows booting OS from your HDD/SSD for faster app opens, web serving and file copying (see notes)
* LED blue indicator indicates drive status
* USB bus-powered
* PCB Size 85mm x 56mm
* Fully compatible with X735 for intelligent power management and cooling your Raspberry Pi
* Fully compatible with X710 for wide input voltage (6~36V) and intelligent power management
* Fully compatible with X765 for powering over Ethernet (POE, 5V 5A)
* Fully compatible with X728 for uninterruptible power supply (18650 UPS, 5.1V 8A)

===How to select your power adapter===
If you have a good quality usb type c power adapter, you can also use a TYPE C power adapter to supply power through X735 type c, otherwise we suggest you choose our power adapter with DC 5525 JACK

==Matching Metal Case==
We use shorter copper spacer to connect Raspberry Pi 4 and X857 V2.0, which reduces the height of the entire product, so the matching metal case X857-C3 is shoter 3mm than X857-C1;
Please refer to [[X857-C3]].
Note: The case of X857 V1.2 and X862 V2.0 are different. X857 V1.2 should use [[X857-C1 Case]], but X857 V2.0 use [[X857-C3]] Case.

==FAQ==
Q1: What to do if HDD/SSD is not recognized?
A: Please refer to [[How to View/Partition/Format/Mount HDD/SSD]]
Q2:What does the red led on the X857 indicate?
A: The red led indicate means 3.3V SSD power supply OK.
