Pin 8 support 2 different signals. Please check your board against the component placement map to find out which signal is routed.

If you have R563 populated on your board, you have GPIO4_C6 on pin 8.

If you have R573 populated on your board, you have PWM_33 on pin 8.

Both resistors are located on the left bottom corner of the map.

Do not populate both resistor!

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

  1. [fan]
  2. # When the temperature is above lv0 (35'C), the fan at 25% power,
  3. # and lv1 at 50% power, lv2 at 75% power, and lv3 at 100% power.
  4. # When the temperature is below lv0, the fan is turned off.
  5. # You can change these values if necessary.
  6. lv0 = 35
  7. lv1 = 40
  8. lv2 = 45
  9. lv3 = 50
  10.  
  11. [key]
  12. # You can customize the function of the key, currently available functions are
  13. # slider: oled display next page
  14. # switch: fan turn on/off switch
  15. # reboot, poweroff
  16. # If you have any good suggestions for key functions, 
  17. # please add an issue on https://rock.sh/rockpi-sata
  18. click = slider
  19. twice = switch
  20. press = none
  21.  
  22. [time]
  23. # twice: maximum time between double clicking (seconds)
  24. # press: long press time (seconds)
  25. twice = 0.7
  26. press = 1.8
  27.  
  28. [slider]
  29. # Whether the oled auto display next page and the time interval (seconds)
  30. auto = true
  31. time = 10
  32.  
  33. [oled]
  34. # Whether rotate the text of oled 180 degrees, whether use Fahrenheit
  35. rotate = false
  36. f-temp = false
