One device, three layers. The PCB turns after opening to reveal the SoM.

01 / ENCLOSURE

The complete assembly.

The enclosure brings the display and embedded electronics into one industrial control computer.

02 / PCB + SOM

The embedded computer.

The STM32MP1 module stays on the custom carrier board, alongside the system interfaces and protected power input.

03 / DISPLAY

The local interface.

A 4.3-inch capacitive touchscreen connects the operator to the embedded Linux platform.

NITRA’S CONTRIBUTION

From architecture
to prototype bring-up.

The work connected the custom electronics, system interfaces and embedded software through one development scope.

System architecture & electronics

Embedded computer architecture, schematic and PCB design, protected power input and interface integration.

Embedded Linux & BSP

Linux platform integration and board support package bring-up for the custom hardware.

Prototype bring-up

Bringing the board, touchscreen and peripheral interfaces together as an integrated embedded system.
