Mini Shield for NanoPi Duo
- The Mini Shield for NanoPi Duo is a dedicated carrier board for the NanoPi Duo. It extends Duo's Ethernet, serial port, audio, USB and etc.
- The mini shield has an onboard JMS567 USB to SATA IC and an mSATA interface.
- The mini shield has an onboard FE1.1s which extends four USB Host ports.
- It has a serial port and Ethernet port.
- It has an onboard microphone and a 3.5mm audio jack.
- The mini shield has a 2 x9 Pin header which extends NanoPi Duo's IO pins.
- There is a 6-pin SPI header on the reverse side.
- This shield's dimension and mounting holes' positions are exactly the same as those of a Raspberry Pi therefore it can well fit into a Raspberry Pi's case.
- its dimension is the same as that of a Raspberry Pi and it can fit into a Pi's case
- 4 x USB Host port
- Serial port and Ethernet port
- Audio input and output
- 2 x 9 Pin GPIO header
- 6 x Pin SPI header
- PCB dimension(mm): 85 x 56
Diagram, Layout and Dimension
Here is a layout of ports and interfaces. There are detailed descriptions for ports and interfaces on the other side of the board.

It can fit into a Raspberry Pi's case. Here is a hardware setup:
Mini Shield for NanoPi Duo_NanoPi_Duo-2
Connect SSD to mSATA
Connect an SSD hard disk to the shield's mSATA, power on the board and type the following command to check the SSD's status:
Boot System from SSD
A NanoPi-Duo can be booted from the SSD on a Mini Shield for NanoPi Duo. Booting OS from an SSD has the following benefits:
1) faster read/write;
2) much longer life time than a TF card;
3) more reliable than booting from a TF card;
You can install an OS to SSD by using the npi-config utility. Here are the steps to follow:
Enter the "Boot Options" menu, go to "Boot device" and you will see two options:
1) D1 Hard drive
2) D2 TF card
Select "D1 Hard drive" and proceed with its prompts.
Select "D2 TF card" to boot OS from a TF card.
If your npi-config doesn't have a "Boot device" menu it might be that your npi-config is out of date and you can update it by selecting "Update" in the menu.
