4.14 Debug UART 

MYS-6ULX-IOT is equipped with a debug UART, which can be used as Linux terminal to 

debug  the  system.  A  pin  header  (1x3pins,  2.54mm  pitch)  has  been  used  for  the  debug 

UART port. The debug UART is 3.3V LVTTL Level standard. Consumers can use it with a 

USB  to  UART  (TTL  level)  cable.  MIYR  provides  suitable  cable  for  selection.For  more
