Raspberry Pi 4B X825 V2.0 User Guide

Overview

This is the new X825 V2.0 version which release at April 1st 2020, there will be a new case X825-C8 designed for X825 V2.0. The X825-C6 or X825-C7 DO NOT SUPPORT X825 V2.0. The X825 V2.0 Version is updated from X825 V1.5 Version.

Some new features of X825 V2.0(Updated on April 1st 2021):

① Add 4 test pins to achieve powered between X825 V2.0 and Pi4 without additional cable. You can get power from the PI4's Type-C port or X825 V2.0 DC JACK power socket.

② Removed the on-board power button and 4-pin external switch interface. You can connect the X735 board for software safe shutdown & power management .

③ Use more shorter USB 3.0 jumper/connector, so the matching metal case is X825-C8 NOT X825-C6.

Features

• Supports upto 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.)
