RPI 3 Pin Diagram

The above mentioned adaptor (PL2303) will support Linux host machine ( ubuntu ) with proper connection between RPI (for both 3B and B+) as below

  • Connect GND (Pin 6) of RPI with PL2303 GND Pin
  • Connect GPIO14 (Pin 8) of RPI with PL2303 RX Pin
  • Connect GPIO15 (Pin 10) of RPI with PL2303 TX Pin

After connection, please run minicom in host machine to establish serial connection with RPI


Note : In usual, adaptor will have device name as ttyUSB0 after connected to host PC ( can be checked using dmesg command in host ). Please configure minicom accordingly. 

Supported drivers for  USB-to-Ethernet Adapters

  •  ASIX based drivers  
  •  r8152 driver (realtek)   

 Validated USB-to-Ethernet Adapters

  1. Does not work the WiFi built-in in the RPI?

    1. Yes. The default wifi antennas in the Raspberry Pi are good enough for you to get a WiFi network( to which you can connect your devices )

    1. Hi Z-André Garcia Vieira 

      Could you please share the Build VM OS version and also the build steps you followed?

  3. Dear support,

    Should we strictly use the above mentioned PL2303 USB to TTL Converter Adapter?

    What about the CH340 USB to TTL?

    BR, Nathan
