Overview
The QSXM is a QFN-style solder-down Computer-on-Module from Ka-Ro electronics, part of the QSX extended family. Measuring 29mm square with a total height of 2.6mm, the QSXM is based on the NXP i.MX 8M Mini processor with quad Cortex-A53 cores at 1.6 GHz and a Cortex-M4 co-processor. Featuring 2GB LPDDR4 RAM, PCIe Gen 2, 4-lane MIPI-DSI display, and 4-lane MIPI-CSI camera interface, it delivers enhanced connectivity and multimedia in the extended 108-pad QFN solder-down format.

Design Advantages
Solder-Down Design
QFN-style module with thermal pad for excellent thermal performance and defined ground plane connection for all signals. Visual solder joint inspection possible after assembly.
Easy PCB Integration
High-speed design compliant. Even 2-layer PCBs can be used thanks to the large ground pad providing a solid ground plane for controlled impedance routing.
EMI Performance
Large ground pad on bottom side provides a defined return path for all signals, minimising loop area and reducing radiation and EMI issues.
Industrial Reflow Compatible
Compatible with industrial standard reflow profile for Pb-free solders. Single-sided assembly with standard contact assignments.
