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_usbis not compiled into the NVIDIA Tegra kernel (JetPack r36.4), so PEAK's proprietary driver is required. - Must be built with
NET=NETDEV_SUPPORTfor standard SocketCAN tools (candump,ip link, etc.). - The module lives at
/lib/modules/$(uname -r)/misc/pcan.koand is loaded viamodprobe 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.
