Model Number
Since the Raspberry Pi 4 changes the form factor(swapping USB and RJ45), we need different USB connection adapter. The ROCK Pi 4 shares form factor with Raspberry Pi 3/3B+. Below is the different model number:
| Model | Description |
|---|---|
| DF4 | Dual version for Raspberry Pi 4 |
| QF3 | Quad version for ROCK Pi 4, Raspberry Pi 3/3B+ |
| QF4 | Quad version for Raspberry Pi 4 |

Getting Started
Power Options
Power consumptions for typical disks:
| Power Consumption | |
|---|---|
| SSD | <3W |
| 2.5 HDD | 3 ~ 5W |
| 2.5 HDD | 5 ~10W |
Note: the table above is for reference, check your disk label for the exact power consumption. More info can be found here.
Option 1: Powering from Raspberry Pi/ROCK Pi 40P GPIO header
The Raspberry Pi GPIO +5V can provide up to 1.5A power, the typical SSD is 3W power consumption. So you can drive up to two SSDs directly powering from Raspberry Pi with good 5V/5A USB C power adapter.
The ROCK Pi 4 GPIO +5V can provide up to 4A current. You can drive four SSD/HDD directly if your power adapter can provide > 35W power.
Option 2: Powering from USB C or DC Jack on SATA HAT
V1.1 SATA HAT
For V1.1 hardware revision, we use USB C for the power input on SATA HAT with PD/QC support. Same as option 1, you can choose USB PD power adapter > 35W to driver up to four 2.5inch HDDs and Raspberry PI at the same time. 3.5inch HDD powering is not supported from the USB C port.
V1.2 SATA HAT
For V1.2, we changed the power jack on SATA HAT to 12V DC because the 12V power adapter is much cheaper than USB C PD adapter. Also, users want to power 3.5inch HDD with power adapter instead of ATX PSU. The 12V DC jack is 5.5x2.1mm diameter. You need at least 12V/3A to power four 2.5inch HDD and 12V/5A to power four 3.5inch HDD.
Option 3: Powering from ATX PSU
If you plan to put the SATA HAT in a PC enclosure, then you can use the ATX PSU. Mostly ATX PSU can meet the power requirement. You need a ATX Floppy cable to power the SATA HAT and Raspberry Pi.
