How to create a TTL/UART Log!

Wath is needed:

1 x Linux or Windows PC
1 x USB to TTL/UART Converter ( Serial-Converter)
3 x connection Cable

UART – GPIO:

The order of 4-pins is almost always the same on each PCB, starting with GND (the only square pin)
Note: Soldering contact pins or cables is not necessary for a PCB with through-hole UART holes, a mechanical connection is sufficient.

PIN-OUT:

1. GND
2. TX
3. RX
4. 3.3V, VCC (IS NOT NEEDED)

1. Connect the PCB pads to the corresponding Serial-Converter ports, and then connect the USB-Connector of the Serial-Converter to the USB port on the PC.

GND (PCB) <←----→-------→----------------> GND (Serial-Converter)
TX (PCB) <-←----→-------→----------------> RX (Serial-Converter)
RX (PCB) <←----→-------→-----------------> TX (Serial-Converter)
USB-Connector (Serial-Converter) <-----> USB-Port (PC)

2. Download Putty and make the following settings:

3. To establish the TTL connection with the board, press the <Open> button and then connect the board to the mains.
