[[File:X857-V2.0-IMG-9471-interface.jpg|thumb|right|X857 V2.0]]
==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]];
* We have solved the EMC interference issue between Raspberry Pi 4 and USB3.0 device ON X857 V2.0.
* 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.
