The Modules will typically use ARM SOCs similar or the same as those used in many familiar devices such as tablet computers and smart phones. Alternative low power SOCs and CPUs, such as tablet oriented X86 devices and other RISC CPUs may be used as well. The Module power envelope is typically under 6W. Two Module sizes are defined: 82 mm x 50 mm and 82 mm x 80 mm. The Module PCBs have 314 edge fingers that mate with a low profile 314 pin 0.5 mm pitch right angle connector (the connector is sometimes identified as a 321 pin connector, but 7 pins are lost to the key). The Modules are used as building blocks for portable and stationary embedded systems. The core CPU and support circuits, including DRAM, boot flash, power sequencing, CPU power supplies, GBE and a single channel LVDS display transmitter are concentrated on the Module. The Modules are used with application specific Carrier Boards that implement other features such as audio CODECs, touch controllers, wireless devices, etc. The modular approach allows scalability, fast time to market and upgradability while still maintaining low costs, low power and small physical size. ![The image displays a logo featuring the text 'SGe'. The uppercase letters 'S' and 'G' are large and lime green, while the lowercase letter 'e' is magenta pink and positioned slightly lower to the right of the 'G'.](.smarc-lec-imx8m-user-s-guide-rev01/3d228b491fa4c3676d6318820e23651074ba0b2376eedc03b1068a15e1399e86.jpg) STANDARDIZATION GROUPFOR EMBEDDED TECHNOLOGIES SMARC module and carrier specifications are available online at: https://www.sget.org/standards/smarc.html # 2.

# 4.3 Signal Description by function # 4.3.1 The First Display Interface The first display interface is a group of 30-pins that is split into a channel 0 and channel 1. The SMARC specification allows to support either dual channel LVDS ports, 2 separate single channel LVDS ports, 2 MIPI DSI ports of 4 lanes each or 2 eDP ports 4 lanes each. A mix of different display type such as DSI and eDP is also permitted. Below tables show which display ports are supported on this particular module

The drawing depicts a rectangular structure divided into three main vertical sections. On the left, there is a mechanism featuring a small top block, a small bottom block, and two thin horizontal lines between them, resembling a latch or slot. The central section is a large, solid vertical rectangle. On the right, there is a top block and a bottom block, similar to the left side but positioned at the edge.
