Overview
The QSRZ is a QFN-style solder-down Computer-on-Module from Ka-Ro electronics, part of the QS Family. Measuring just 27mm square with a total height of 2.3mm, the QSRZ is based on the Renesas RZ/G2L processor with dual Cortex-A55 cores at 1.2 GHz, a Cortex-M33 co-processor, and an ARM Mali-G31 GPU. It features an H.264 Video Codec Processor, 24-bit RGB and MIPI-DSI display interfaces. The module uses a QFN lead style with 1mm pitch and 100 pads including a thermal pad, enabling visual solder joint inspection after assembly and single-sided PCB assembly.

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.
