UART Pins Function Description
Label Definition Function
RX
SD02B UART
Receive Pin
This is SD02B’s UART receive pin. It should be
interfaced to 5V logic UART. It should be connected
to host’s transmit pin.
TX
SD02B UART
Transmit Pin
This is SD02B’s UART transmit pin. It should be
interfaced to 5V logic UART. It should be connected
to host’s receive pin.
GND
System Ground
Common ground for both logic operation and also
stepper power source.
NC
Not Connected Leave this pin disconnected.
