Overview
The QSBASE4 Eval Kit + QSMP-2550 is the AI-ready evaluation platform for the Ka-Ro STM32MP255F module — the high-end of ST's STM32MP2 series with dual Cortex-A35 cores, Cortex-M33, a 1.35 TOPS Vivante NPU and HiFi4 audio DSP. Pre-fitted in the QSBASE4 socket; ideal for industrial vision, motor control and secure Industry 4.0 gateways.
What's in the Box
QSBASE4 Baseboard

QSBASE4 Baseboard Features
Why this Kit?
One Socket, Every Module
The 0.5 mm Hirose socket on QSBASE4 accepts every QS-family /SOCK module — i.MX 93, i.MX 91, STM32MP, RZ/G2L and more. Test multiple processors on the same baseboard.
Industrial AI & Vision
1.35 TOPS Vivante NPU and HiFi4 DSP make QSMP-2550 a single-chip platform for vision, voice and motor-control HMI workloads.
Production Migration
Evaluate on this kit, then ship the same code base on the solder-down production module. No carrier-board re-spin, no software port.
Made in Germany
QSBASE4 and QS-family modules are designed and manufactured by Ka-Ro Electronics. 12-month warranty and 10+ year availability commitment.
Software & Support
Yocto-Linux BSP
Reference image based on Yocto kirkstone / scarthgap. Boots straight to a Linux console out of the box.
Mainline U-Boot + Linux Kernel
Long-term-supported sources, including Ka-Ro device-tree overlays and module-specific patches.
NPU SDK
NXP eIQ machine-learning toolkit (or vendor equivalent), NPU runtime and TensorFlow-Lite / ONNX Runtime support out of the box.
