  • 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.

Applications

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:

fdisk -l

Here is what you expect to observe:
Check SSD

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:

sudo npi-config

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If your npi-config doesn't have a "Boot device" menu it might be that your npi-config is out of date and you can update it by selecting "Update" in the menu.

Audio

1. Audio Recording:

arecord -D hw:00 -f cd test.wav
