# Bill of Materials

## PEAK-System PCAN-USB

| Field | Value |
|-------|-------|
| **Manufacturer** | PEAK-System Technik GmbH |
| **Model** | PCAN-USB |
| **USB ID** | `0c72:000c` |
| **Purpose** | USB-to-CAN adapter for reading car CAN bus traffic |
| **Interface** | SocketCAN netdev (`can1`) |
| **Default bitrate** | 500 kbps |
| **Driver** | PEAK proprietary driver 9.2.0 (netdev build) — out-of-tree module, must be rebuilt after kernel updates |

### Notes

- The mainline kernel driver `peak_usb` is not compiled into the NVIDIA Tegra kernel (JetPack r36.4), so PEAK's proprietary driver is required.
- Must be built with `NET=NETDEV_SUPPORT` for standard SocketCAN tools (`candump`, `ip link`, etc.).
- The module lives at `/lib/modules/$(uname -r)/misc/pcan.ko` and is loaded via `modprobe pcan`.
