# 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`.

||
## Waveshare SIM7600G-H-M.2
|
||
|
||
| Field | Value |
|
||
|-------|-------|
|
||
| **Manufacturer** | Waveshare (SIMCom SIM7600G-H-M.2 module) |
|
||
| **Form factor** | M.2 B KEY |
|
||
| **Purpose** | LTE Cat 4 cellular + multi-constellation GNSS (GPS, Beidou, GLONASS, GALILEO, QZSS) |
|
||
| **Interface** | USB (ttyUSB* for AT commands/NMEA, usb0 for RNDIS Ethernet) |
|
||
| **Power** | 3V – 4.2V (board rail) |
|
||
| **Antennas** | 3× IPEX (LTE main + LTE diversity + GNSS) |
|
||
| **Max data rate** | 150 Mbps DL / 50 Mbps UL (LTE Cat 4) |
|
||
|
||
### Required software
|
||
|
||
| Package | Purpose |
|
||
|---------|---------|
|
||
| `gpsd` | Decode NMEA from the GNSS ttyUSB port |
|
||
| `minicom` (or `picocom`) | AT command terminal for module configuration |
|
||
| `dhclient` / `NetworkManager` | Bring up the RNDIS network interface (`usb0`) |
|
||
| `ppp` (optional) | If dial-up (ATD*99#) is preferred over RNDIS |
|
||
|
||
### Notes
|
||
|
||
- The module presents multiple USB serial ports (`/dev/ttyUSB0`–`/dev/ttyUSB4`) — typically ttyUSB2 for AT commands, ttyUSB3 for NMEA GPS data.
|
||
- USB PID switching (`AT+CUSBPIDSWITCH=9011,1,1`) may be needed to expose the RNDIS network interface.
|
||
- M.2 B KEY is **not** mechanically compatible with Mini-PCIe.
|
||
- Supply voltage should be ~4.0 V for reliable operation.
|
||
- DO NOT hot-plug while powered.
