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
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.
