# MR-CANHUBK3

## What is this board?

MR-CANHUBK344 is an evaluation board for mobile robotics applications such as autonomous mobile robots (AMR) and automated guided vehicles (AGV). Based on the Arm® Cortex®-M7 [S32K3](https://www.nxp.com/products/processors-and-microcontrollers/s32-automotive-platform/s32k-auto-general-purpose-mcus/s32k3-microcontrollers-for-automotive-general-purpose:S32K3) general-purpose automotive microcontroller (MCU), featuring advanced safety, security and software support.

MR-CANHUBK344 includes 100BASE-T1 Ethernet ([TJA1103](https://www.nxp.com/products/interfaces/ethernet-/automotive-ethernet-phys/asil-b-compliant-100base-t1-ethernet-phy:TJA1103)) and six CAN FD ports (available in the S32K344). The six CAN ports are two each of CAN FD, CAN SIC (signal improvement) and CAN SCP (secure). Tunneling CAN over Ethernet using IEEE 1722 is one use case for this. The [SE050](https://www.nxp.com/products/security-and-authentication/authentication/edgelock-se050-plug-and-trust-secure-element-family-enhanced-iot-security-with-high-flexibility:SE050) Secure Element with Near Field Communication (NFC) as well as other general purpose peripheral interfaces are also accessible on DroneCode standard JST-GH connectors.
