• ROCK 5A
• ROCK 5C

note

ROCKPi 4 Series vs. ROCK 4 Series Compatibility Note: ROCKPi 4 series is the early product name, now unified as the ROCK 4 series.

• ROCKPi 4A = ROCK 4A
• ROCKPi 4B = ROCK 4B
• ROCKPi 4A+ = ROCK 4A+
• ROCKPi 4B+ = ROCK 4B+
• ROCKPi 4SE = ROCK 4SE

ROCK 4A/4A+/4B/4B+/4SE are fully compatible with ROCKPi 4A/4A+/4B/4B+/4SE and all are fully compatible with Penta SATA HAT. If your device is labeled as ROCKPi 4A/B/4SE, please refer to the installation guide for the corresponding ROCK 4A/B/4SE.

Currently supported Raspberry Pi models:

• Raspberry Pi 5

Feature

• Up to 5x HDD/SSD, support 2.5inch or 3.5inch SSD, up to 100T Storage
• 4x SATA + 1x eSATA with power
• Utilize PCIe buses on ROCK Series and Raspberry Pi
• External standard ATX power supply support for HDDs and SBC itself
• 12V DC power input for 2.5/3.5 HDD power and SBC itself (polarity: center positive)
• Support HDD suspend mode
• Support software RAID 0/1/5
• Optional PWM control fan for HDD heat dispatching
• Optional OLED display for IP/Storage info

tip

If you use large capacity 3.5-inch mechanical hard drives on the Penta SATA HAT, you need to check the hard drive specification to determine the peak current of the hard drive. We recommend using a hard drive with a peak current less than 1.7A.

Components and troubleshooting scope

The Penta SATA HAT family is commonly used in the following combinations:

• Base board: the storage board used for SATA connectivity
• Top board (optional): adds the OLED display and fan; see Penta SATA HAT top board
• Full kit: base board + top board + the matching accessories

If you run into installation or boot problems, identify which combination you are using before troubleshooting further:

1. With only the base board connected, first confirm the system image, kernel version, and whether the SATA devices are detected
2. Install the rockpi-penta package only when the top board is present, because it is used for the OLED and fan features
3. If the system becomes unstable after connecting the IPEX cable, record the board model, whether you are using the base board or the full kit, and any serial or kernel logs
