UART Debugging

So you can debug the boot process, we include a UART header. Unfortunately to keep Tux without a bunch of holes we had to make this a surface mount part, however due to how it is you should be able to solder wires to it.

If you are consistently debugging, you can solder a pin header directly onto it. This model should work, however double check before you buy as it is untested.

For UART debugging https://github.com/tio/tio is recommended (minicom has some issues, avoid minicom for this), the baud rate should be 115200.

The pinout is as follows:

  1. +5V
  2. UART_TX
  3. UART_RX
  4. GND
