Getting Started
Power Options
Power consumption for typical disks:
| Power Consumption | |
|---|---|
| SSD | <3W |
| 2.5 HDD | 3 ~ 5W |
| 3.5 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 a 12V DC power jack on SATA HAT since the 12V power adapter is much cheaper than a USB C PD adapter. Also, users want to power a 3.5inch HDD with a power adapter instead of an ATX PSU. The 12V DC jack is 5.5x2.5mm in 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 an ATX 4P HDD power cable to power the SATA HAT and ROCK Pi 4.
Software configuration
Just edit /etc/rockpi-penta.conf, take it effect by below command
sudo systemctl restart rockpi-penta.service
Below is the default /etc/rockpi-penta.conf, which you can modify according to the comments
[fan]# When the temperature is above lv0 (35'C), the fan at 25% power,
# and lv1 at 50% power, lv2 at 75% power, and lv3 at 100% power.
# When the temperature is below lv0, the fan is turned off.
# You can change these values if necessary.
lv0 = 35
lv1 = 40
lv2 = 45
lv3 = 50
[key]# You can customize the function of the key, currently available functions are
# slider: oled display next page
# switch: fan turn on/off switch
# reboot, poweroff
# If you have any good suggestions for key functions,
# please add an issue on https://rock.sh/rockpi-sata
click = slider
twice = switch
press = none
[time]# twice: maximum time between double clicking (seconds)
# press: long press time (seconds)
twice = 0.7
press = 1.8
[slider]# Whether the oled auto display next page and the time interval (seconds)
auto = true
time = 10
[oled]# Whether rotate the text of oled 180 degrees, whether use Fahrenheitrotate = false
f-temp = false
