RAMN

<img src="https://ramn.readthedocs.io/en/latest/_images/ramn_simple_setup.jpg" width="600">

RAMN (Resistant Automotive Miniature Network) is a miniature CAN/CAN-FD testbed of four Electronic Control Units (ECUs) consiting solely of Printed Circuit Boards. The ECUs can be programmed to emulate the same network traffic as PASTA, another project from our team. RAMN is powered over USB and can be recognized as a standard CAN adapter. It can be connected in closed-loop with the autonomous driving simulator CARLA. What happens to the virtual vehicle has an impact on the physical CAN/CAN-FD bus, and vice versa. RAMN can be expanded with many stackable expansions, ranging from external quadSPI memories to Trusted Platform Modules (TPMs).

Please check the Documentation for demonstrations and details.

Fabricating RAMN boards

This project is open-source and RAMN boards can be fabricated by most PCB assembly prototyping services.

We have setup 're-orders' at PCBWay. Please see the docs 'PCB Ordering' for more details. You can also request a prototype from any PCB manufacturer, using the Gerber files and BOM in the Hardware folder.

Feel free to contact us if you need assistance to fabricate or sell RAMN boards.

Because component availability is subject to change, we are periodically updating the hardware. The original RAMN hardware data is available in misc/RAMN_V1_reference_PCB.zip, and is recommended for academic purposes.
