Mini Shield for NanoPi Duo 底面

• 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.

2 Hardware Spec

• 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
