General Specification
•Power Supply : 12V, 2A Power Input Jack
•Form Factor : 120mm X 120mm Nano ITX
1PCIe is not supported in i.MX 8M Nano SoC.
2In i.MX 8M Nano µQseven SOM, USB2.0 OTG is only supported in Flash mode
3Either HDMI or LVDS can be supported at a time. By default, HDMI is supported.
4JTAG connector is supported always in Qseven carrier board hardware. If µQseven SOM supports JTAG interface on
Qseven Edge connector, then JTAG can be tested in Qseven carrier board. In i.MX 8M Mini or i.MX 8M Nano SoC based
µQseven SOM, JTAG is not supported in Qseven Edge connector by default.
