Firmware and Python userspace library for the comma.ai panda, a USB CAN and CAN FD interface device built on the STM32H725 microcontroller. It enforces vehicle-specific safety logic compiled in from opendbc and is designed for use with openpilot driver assistance systems.

Use cases

• read and send CAN messages from a car over USB
• interface with vehicle CAN bus from Python
• flash firmware onto a panda CAN interface device
• develop and test vehicle safety models for openpilot
• sniff CAN traffic on multiple buses
• build hardware-in-the-loop tests for automotive safety logic

When to choose

• you own a comma.ai panda device and need to interact with it
• you are developing openpilot or vehicle safety logic
• you need a safety-critical, MISRA-checked CAN interface firmware
• you want a Python API for CAN communication with a car

When to avoid

• you need a general-purpose CAN adapter without comma.ai hardware
• you want a pure software CAN simulator with no hardware component
• you need OBD-II diagnostics tooling rather than raw CAN access
