i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini from Engicam.
General features: - NXP i.MX8M Mini - Up to 2GB LDDR4 - 8/16GB eMMC - Gigabit Ethernet - USB 2.0 Host/OTG - PCIe Gen2 interface - I2S - MIPI DSI to LVDS - rest of i.MX8M Mini features
i.Core MX8M Mini needs to mount on top of Engicam baseboards for creating complete platform solutions.
