# Ocelot

Ocelot is a universal CAN gateway and interceptor designed to make retrofitting of existing vehicle components like the iBooster or Corolla EPS easier. It is also firmware-compatible with Comma.ai Panda, allowing it to be used with tools like Cabana for CAN data visualization/analysis.

### Where to get it?

It can be obtained from the [RetroPilot Shop](https://shop.retropilot.org/product/ocelot-can-gateway/) or you can build it yourself from the [board files and BOM.](https://github.com/RetroPilot/ocelot/tree/main/hardware)

### How do I connect it to my RetroPilot device?

While there's a USB-C *(not OBD-C)* connector on the Ocelot, it's used just for firmware flashing via PC and diagnostics. The actual commanding of the Ocelot is communicated via CAN. 

### What's the interface on it?

The Ocelot includes **3x CAN bus** interface, that allows you reading and sending whatever CAN messages your project needs! USB-C interface for flashing the firmware is also included. For more information on programming it to send the CAN messages you need, see the [firmware section](broken://pages/1vQBm9eOaFfWRm8nDtYm).
