Computing

NXP i.MX 8M Mini Processor running Yocto Linux with ROS2 in Docker.

• 4 x ARM Cortex-A53 up to 1.8 GHz / core
• 1 x ARM Cortex-M4 up to 400 MHz
• 2GB low power DDR4 DRAM
• 16GB eMMC flash module

STM32H747XI Micro-Control-Unit running bare-metal firmware for real-time applications.

• Cortex-M7 core up to 480 MHz with double-precision FPU
• Cortex-M4 core up to 240 MHz with FPU
• 1 MB RAM
• 2 MB Flash

L x W x H = 101 x 42/33 x 18 mm

Industrial temperature range: -40 °C to +85 °C

Interfaces

Industrial Wired Interfaces

All industrial wired interfaces are galvanically isolated to prevent ground-loops and increases overall system resilience.

• 2 x CAN / CAN FD (Controller Area Network)
• 2 x RS485
• Gigabit-Ethernet (1000BASE-T)
• Single-Pair Ethernet (10BASE-T1S)

Other Wired Interfaces

• Debug-UART providing a Unix shell
• USB-C for flashing the Yocto image and connecting via adb (Android Debug Bridge)

Wireless Interfaces

• WiFi (Murata 1DX)

Miscellaneous

• 9-DoF (Degree-of-Freedom) IMU (Inertial Measurement Unit)
• EEPROM for configuration storage (24LC256)

Power Supply

• Power-over-Ethernet (PoE via Gigabit-Ethernet)¹
• Power-over-Data-Lines (PoDL via Single-Pair Ethernet)¹
• USB-C

¹ Power supply via PoE and PoDL is also galvanically isolated.
