The USB-C connector is small, but convenient to use and resistant to damage. Additionally, it allows for the conduction of significant currents and can be used in the latest generation of interfaces - USB 3.x. These features make USB-C replace the old standards of USB connectors in many applications, which is why KAmod USB-UART-mini has been equipped with a USB-C connector.

|}
</center>
The serial interface connector is adapted to mount goldpin pins with a pitch of 2.54 mm, but it also allows for soldering wires directly to the converter board. The signals derived on the connector are as follows:
:* TX – data output from the serial UART interface;
:* RX – data input to the UART interface;
:* 5V – power output with a value of approx. 5 V supplied to the USB connector;
:* GND – power/signal ground.

=====Voltage level on UART interface lines =====
The RX and TX lines of the UART interface operate at a voltage of 3.3 V. Additionally, the RX input tolerates higher voltages, up to a maximum of 5 V. 
Optionally, the module can be configured so that the RX and TX lines of the UART interface operate at a voltage of 5 V. Permanently shorting the pads located on the bottom of the board, marked "Vio=5V", with a drop of hot solder, will cause the interface to operate at a voltage of 5 V.

Mounting the converter requires making a main hole with a diameter of 11 mm and two holes in one line, for mounting screws with a diameter of approx. 2...3 mm at a distance of 8.75 mm from the center of the main hole. An example of the assembly is shown in the photos:
