Overview
The QS93 is a QFN-style Solder-Down Computer-on-Module from Ka-Ro electronics, part of the QS Family. In a compact 27mm x 27mm x 2.6mm form factor with 1mm pitch and 100 pads, the QS93 delivers dual-core Arm Cortex-A55 processing at 1.5 GHz alongside a Cortex-M33 real-time core, making it ideal for industrial IoT, edge AI, and vision applications. The module features NXP's i.MX 93 processor with an integrated Arm Ethos U-65 microNPU for machine learning inference at the edge, plus the EdgeLock secure enclave for hardware-rooted security.

Design Advantages
QFN-Style Solder-Down
Compact 27mm square QFN package with thermal pad. Single-sided assembly leaves the underside of the carrier board free, and visual solder joint inspection remains possible after soldering.
QS Family Pin-Compatible
Standard QS pinout across the QS Family enables a scalable platform strategy. Design one baseboard and migrate between processors as application requirements evolve.
Defined Return Path
A large ground pad on the bottom side provides a defined ground plane connection for all signals, minimising EMI and supporting cost-effective 2-layer baseboard designs.
Industrial Longevity
Industrial-grade components rated for -40°C to +85°C operation with long-term availability commitment, ensuring your product design remains in production for years.
