UART Default Baud Rate for Libre Computer Boards

Below are the default baud rates for each board

  • ALL-H3-CC H3/H5 115200
  • AML-S805X-AC 115200
  • AML-S905X-CC 115200
  • AML-S905D-PC 115200
  • ROC-RK3328-CC 1500000
  • ROC-RK3399-PC 1500000

Remember to turn off flow control since CTS/RTS lines are not connected. For AML- prefixed boards, the tty device is usually ttyAML0 rather than ttyS0.
