Product Introduction

SSOM-K1 is an ultra-compact SoM (System on Module) with SpacemiT K1 System on Chip(SOC).The module integrate with high speed LPDDR4X SDRAM, eMMC, NOR Flash, power monitoring IC (PMIC), and two Ethernet PHY.

SSOM-K1 provide extensive connectivity options, including USB 2.0, USB 3.0, Gigabit Ethernet, MIPI-CSI, PCI Express, as well as HDMI and a 4-lane MIPI-DSI Display interface. These remarkable features position the SOM as an exceptional choice for a wide variety of embedded applications.

Since most of the SoC signals can be connected through the SODIMM connector, most of the SoC functions are available.
