Mini Shield for NanoPi NEO Core/Core2
- The Mini Shield for NanoPi NEO Core/Core2 is a custom SDK carrier board developed for the NanoPi NEO Core and NanoPi NEO Core2. It has Ethernet port, serial debug port, audio, USB port and etc.
- 1 x Onboard JMS567 USB to SATA IC and 1 x M.2 SSD interface for connecting a 2242 SSD.
- 2 x USB Host ports.
- 1 x Serial debug port for connecting a serial communication board and 1 x Ethernet port.
- 1 x Onboard Microphone and 1 x 3.5mm audio jack for audio recording and playing.
- 2 x 13 Pin header which populate the NanoPi NEO Core/Core2's IO pins.
- 1 x button and 1 x IR interface for working with a remote control
- Room for an SPI Flash(SOP8-200mil) is reserved. Users can solder an SPI flash on the board.
- It has the same dimension and mounting holes as those of a Raspberry Pi. The whole board can be well fit into a RPi's case
- Same form factor as RPi, can be well fit into a RPi's case
- 2 x USB Host
- 1 x Serial debug port and 1 x Ethernet port
- 1 x audio input and 1 x audio output
- 2 x 13 Pin GPIO pin-header
- 1 x Button
- 1 x M.2 2242 SSD interface
- 1 x IR receiver interface
- PCB dimension(mm): 85 x 56
The Mini Shield for NanoPi NEO Core/Core2's layout of interface and connectors is shown on the right. On its back there are silkscreens of description for the connectors and pins.
When you mount a NanoPi NEO Core or NanoPi NEO Core2 to a Mini Shield be aware of the Core/Core2's mounting position. Each pin-header's first pin is marked as a triangle.

1. M.2 2242 SSD Interface
Insert an SSD hard drive to the M.2 2242 interface. After system is booted you can check the SSD device by running the following command:
2. Boot OS from SSD
You can boot a NanoPi NEO Core or Core2 from an SSD hard driver inserted in a Mini Shield for NanoPi NEO Core/Core2. This way of booting an OS has the following advantages:
1) faster read/write;
2) an SSD has much longer life than a TF card;
3) more reliable than booting from a TF card;
You can install an OS to an SSD hard drive by using the npi-config utility. Here is a command to start the npi-config utility:
After the utility shows the "Boot Options" menu select "Boot device" and you will see the following two options:
1) D1 Hard drive
2) D2 TF card
Select "D1 Hard drive" to boot from an SSD hard drive.
If you want to boot an OS from a TF card you need to select "D2 TF card".
If your npi-config utility doesn't have "Boot device" on its menu you may need to update your npi-config utility by running the "Update" function on the menu.
