Jetson Nano

The LC29H GPS/RTK HAT is compatible with the NVIDIA Jetson Nano via its 40-pin GPIO header. The physical connection is identical to Raspberry Pi.

Connection

Mount the HAT on the Jetson Nano’s 40-pin header. The same jumper positions apply:

• Position B — UART mode via GPIO pins
• Position A — USB mode via USB-C

UART Device Path

The Jetson Nano uses a different UART device path than Raspberry Pi:

# Jetson Nano GPIO UART
lc29h --port /dev/ttyTHS1 info

Note

The exact UART device path depends on your JetPack version and device tree configuration. Check ls /dev/ttyTHS* to find available serial ports.

USB Mode (Recommended)

USB mode avoids UART device path differences across platforms:

# USB mode works the same on all platforms
lc29h --port /dev/ttyUSB0 info

Setup

Follow the Raspberry Pi guide for general setup steps — the software configuration is the same. The key difference is the UART device path when using GPIO serial.

# Install the CLI
uv tool install lc29h

# Monitor position
lc29h --port /dev/ttyUSB0 monitor
