EAORA04: The Newest Generation of ARCU Launched
We are proud to announce that Ecotron’s latest ARCU EAORA04-D with 200 TOPS of calculation performance has been released! It is an intelligent computing platform developed by Ecotron, for autonomous robotic systems using NVIDIA Jetson Orin chip and Infineon TC297. Using the supporting basic software and development tools, developers can build an L4 level low-speed autonomous robotic system in a safe, convenient, and efficient manner.
NVIDIA Jetson Orin is designed for embedded intelligent systems including autonomous robotic systems which can be used to implement autonomous robotic function such as sensor fusion, environment perception, and path planning, etc. Infineon TC297 is based on TriCoreTM architecture with a 300MHz operating frequency and an ECC (Error Correction Code) protected RAM with 728KB + 8MB capacity. It is designed based on the ISO26262 standard and supports ASIL-D safety level requirements. Developers can develop and deploy vehicle control and functional safety related strategies based on the MCU.
