This is new updated X857 V2.0 version from X857 V1.2.
- 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.
- 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
- 1 x X857 V2.0 mSATA SSD shield
- 1 x USB3.1 jumper
- 6 x Screw M2.5 *6mm
- 4 x Spacer M/F M2.5 *7+6mm
- 4 x Spacer F/F M2.5 *9.5mm
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.
