1. Introduction

1.1 LEC-iMX8M Plus

ADLINK LEC-iMX8MP is a SMARC module based on NXP iMX8M Plus (4-core Arm Cortex-A53) processor with an optional Neural Processing Unit (NPU)

operating at up to 2.3 TOPS. It is the first SMARC Revision 2.1 module focusing on machine learning and vision, advanced multimedia, and industrial

IoT, and with high reliability. The module also supports dual-image signal processors and 2x camera inputs for an effective vision system, and is

especially suited for applications such as smart home, smart city, and industrial 4.0.

1.2 The SMARC Form Factor

The SMARC (“Smart Mobility ARChitecture”) is a versatile small form factor Computer on Module definition targeting applications that require low

power and high performance at low costs. Typically under 6W, the modules often utilize ARM and other alternative low-power option CPUs, and are

used in many familiar handheld devices, such as tablet computers and smart phones.

Two module sizes are defined in SMARC: 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, with 7 pins used by the key).

SMARC 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. 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, faster time to market and upgradability while still maintaining low costs, low power, and small physical size.

SMARC module and carrier specifications are available online at: https://www.sget.org/standards/smarc.html
