Model Number
The Penta SATA HAT is designed for ROCK Pi 4, one model only.
| Model | Description |
|---|---|
| PF4 | Support four 2.5/3.5inch HDD/SSD plus one eSATA |
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 ROCK Pi 40P GPIO header
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 12V DC Jack on SATA HAT
For Penta SATA HAT, we use 12V DC power jack on SATA HAT since 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/4A to power four 2.5inch HDD plus eSATA and 12V/6A to power four 3.5inch HDD plus eSATA.
Option 3: Power 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 4P HDD power cable to power the SATA HAT and ROCK Pi 4.
