Geekworm NASPi Gemini 2.5 Dual 2.5'' SATA HDD NAS Storage Kit with DC 6-18V Wide Voltage Input|Safe Shutdown|Auto Power On|RAID for Raspberry Pi 4

Difference of X882 V2.0 and X1.3: Change the DC Jack from 5V input to 6V-18V width voltage input.

Note:

1. The script must be installed first for the product to work properly!!!
2. For better system compatibility & performance, please format your HDD/SSD to Ext4 file system.
3. Power NASPi Gemini 2.5 via DC jack of X882 V2.0, DO NOT power via Raspberry Pi 4!!!
4. Because the shielding of the metal casing will cause the loss of 2.4G wifi signal, we only recommend you to use Ethernet or 5G WiFi.
5. Support Max 16mm thickness 2.5" SATA HDD/SSD installation.
6. Support Max 7mm thickness heatsinks on Raspberry Pi 4 as we use 11mm height spacers for the fan with bracket installation on Pi4.
7. Insert the SD card into Raspberry Pi 4 first before NASPi Gemini installation start.
8. 5G WiFi is stable enough, recommend using Ethernet or 5G WiFi. (2.4G WiFi is not recommend.)
9. The Raspberry Pi, 2.5" SATA SSDs/HDDs, power adapter are all not included in the packing list.

Overview：
Geekworm NASPi Gemini 2.5 is an ultra-compact dual 2.5 inch SATA HDD/SSD NAS storage kit with safe shutdown, auto power on& RAID function that specially designed for Raspberry Pi 4 Model B computer, it allows two pcs 2.5" HDD/SSD to working at the same time with your Raspberry Pi 4. Also support use with one single 2.5" SATA HDD/SSD.

The SuperSpeed USB 3.0 port delivers a blistering data transfer rate of up to 5Gbps, letting you transfer a large amount of data in seconds.

NASPi Gemini 2.5 is composed of three parts: X882 dual 2.5" SATA HDD/SSD shield, NASPi Gemini metal case and heat dissipation system(3Pin 4010 PWM fan with metal bracket). To get better heat dissipation of NASPi Gemini, it also support install Max 7mm thickness heatsink above Pi4, as we use the M2.5*11+6mm spacers to fix the PWM fan with bracket.There is space for extra heatsink installation on Pi 4.

Features 

• Model: NASPi Gemini 2.5
• Ultra-compact NAS storage solution for Raspberry Pi 4 with Dual 2.5" SATA HDD/SSD
• For use with Raspberry Pi 4 Model B only
• Supports Dual Max 16mm thickness 2.5 SATA HDDs/SSDs working at the same time
• Support Auto Power On function by jumper setting (Automatically turn on when there is a power supply)
• Support Software & Hardware safe shutdown function(Integrated on X882 shield, do not need extra expansion board)
• Support connecting 3pin PWM fan for cooling
• Support Three RAID Modes by jumper setting
• UASP supported only, do not support TRIM
• Allows booting OS from your HDD/SSD for faster app opens, web serving and file copying
• Compatible with all Raspberry Pi operating systems (If the OS (such as Home Assistant) does not allow the installation of external scripts, then the software safe shutdown and automatic adjust fan speed functions are not supported;)

• Via DC5521 Jack of X882, 6-18Vdc , ≥4A (DC5525 Jack is compatible with DC5521, also support 5V PSU with DC5525 Jack)

Note about PSU:
Please use high quality power adapter, or the HDD/SSD may cannot be recognized. Since NASPi Gemini 2.5 can install two pcs 2.5 inch hard drives, it needs a high-quality power supply to provide enough current.

Warning about power supply:

1. Don't use that adjustable voltage power supply
2. Don't use the same power supply used on LED strips

The above two are absolute garbage power supply, can not be used.

Cooling Solution

• NASPi Gemini 2.5 uses the same cooling scheme as the NASPi, we only increased the height of the copper spacers from 6mm to 11mm to allow a heatsink with a maximum thickness of 7mm to be placed on the CPU chip of Pi 4.
• NASPi Gemini uses 4010 PWM cooling fan, can support automatic adjustment of speed according to CPU temperature, need to install the shell script.

Raid Setting

Please refer to: How to Configure RAID Setting

Note: NASPi-Gemini 2.5 is a hardware RAID. It supports RAID at the hardware level and does not require any software configuration. There is nothing to do with software, even if OMV does not support RAID settings;

(Once you set the RAID mode successfully, you need to partition&format&mount the hdd/ssd, so that it can be recognized by your Raspberry Pi OS. please refer to How to View/Partition/Format/Mount HDD/SSD)

Button Swtich Operation Guide

• Press button switch to turn on
• Press button switch and hold for 1~2 seconds to reboot
• Press button switch and hold for 3 seconds to implement safe shutdown

The above operations will only successed after the script has been successfully installed.

• Press button switch and hold for more than 8 seconds to force shutdown
