2. Installasjonsinstruksjoner
The waveshare USB to TTL Serial Adapter Cable is designed for plug-and-play compatibility with various operating systems including Windows 7/8/8.1/10/11, Mac, Linux, and Android. Drivers for the FT232RNL chip are typically installed automatically by your operating system. If not, they can be downloaded from the FTDI webnettstedet.
2.1. Connecting to Raspberry Pi 5
This adapter is suitable for UART debugging on Raspberry Pi devices. You can connect it using two primary methods:
- Via SH1.0 3PIN cable: Connect to the Raspberry Pi 5 UART Debug Connector.
- Via Separated 4PIN Header: Connect to the Raspberry Pi 40PIN GPIO UART Interface.

2.2. Pinout Definition and Voltage Level Switching
The adapter features a TTL serial port with a 3.3V/5V level translation circuit, allowing you to switch the communication level as needed for your target device. The pinouts are clearly defined:
- VCC: 3.3V or 5V output, configured by a switch on the adapter.
- GND: Jordforbindelse.
- TXD: Transmit Data. Connects to the MCU.RXD (signal direction: MCU.RX <-- FT232 <-- PC.TX).
- RXD: Receive Data. Connects to the MCU.TXD (signal direction: MCU.TX --> FT232 --> PC.RX).

3. Betjening av enheten
Once connected to your computer's USB port and your target device, the adapter will begin operation. The onboard LED indicators provide visual feedback on the device's status.
3.1. LED-indikatorer
The adapter features three LED indicators for easy monitoring of its operating status:
- PWR (strømindikator): Turns on when there is a USB connection and voltage er oppdaget.
- TXD (Transmit Indicator): Turns on while the USB port is sending data.
- RXD (Receive Indicator): Turns on while the device port is sending data back.

4. Vedlikehold
The waveshare USB to TTL Serial Adapter Cable features a robust plastic case with a sandblasting process finish, designed for long-lasting durability. To ensure optimal performance and longevity:
- Hold enheten ren og fri for støv og rusk.
- Unngå å utsette enheten for ekstreme temperaturer eller fuktighet.
- Handle the cable and connectors gently to prevent damage.
5. Feilsøking
If you encounter issues with your USB to TTL Serial Adapter Cable, consider the following:
- No Power Indicator (PWR LED off): Ensure the USB cable is securely connected to both the computer and the adapter. Try a different USB port or computer.
- Ingen dataoverføring (TXD/RXD-lampene blinker ikke): Verify that the TXD and RXD pins are correctly connected to your target device's RXD and TXD pins, respectively. Check the voltage level switch (3.3V/5V) to ensure it matches your device's requirements. Confirm that the drivers are correctly installed on your operating system.
- Tilkoblingsproblemer: Ensure your target device is powered on and functioning correctly. Check for any loose connections in the jumper wires.
For persistent issues, please refer to the 'Warranty and Support' section for technical assistance.
