Geekworm Raspberry Pi X820 V3.0 SATA HDD/SSD Storage Expansion Board

(V3.0 Upgrade Features)
Using patch process to improve the quality of the X820 V3.0 Board;
Add Powers button switch on the board to control the power supply.
Add upgraded external 5V 2A power output USB port for external device such as cellphone and other device, of course. User can power the raspberry pi via this USB port when GPIO pins are occupied by other expansion board.
Use upgrade Main control chip to solve the problem that the 'reboot' command is not supported in the V1.3 function.
User can directly use the X820 V3.0 board as a mobile hard disk even if you don't power it (tested; with our USB3.0 cable or use a good quality and relatively short USB3.0 cable); PS: In the V1.3 version, you need to power the X820 at the same time as when you use the X820 V1.3 board as a mobile Hard disk;
The HDMI adapter has been removed, which reduces the difficulty of installation; it also facilitates the design and installation of the accessory enclosure;
Two kinds of power supply modes are supported; One of mode is that power the raspberry pi via 2 pin cable by connecting to GPIO2 (5V) and GPIO3(GND) pins, the other one of mode is power the raspberry pi via USB port; PS: DON'T USE THE TWO KIND MODES AT THE SAME TIME;
Note:
Because the PCB layout is changed so that the old metal case for X820 V1.3 version (SKU: 483342) is not fit to X820 V3.0 board, the new metal case will release soon.
