Level-shifter

The USB to RS232 outputs only 3,3V on TX signal. But the board provides both 5V and 3.3V output for driving external Electronics. The hardware I will use this level-shifter om has also the RX signal inverted. Thats the reasson for only Three Inverter gates. I would likely used four of them on a normal USB to RS232 with level-shift, or maybe an 74HC04 SO. But I allready had these gates and the cheep Silabs USB to RS232 laying in my drawer. Next time I'll redesign and fit all in one PCB. The requirement is a small design. It will be used between a Raspberry Pi 3 and an home appliances in our labratory at my work. BTW... Thank you PCBGOGO for the high quality and Quick delivery of the PCB-boards. You also gave me a few extra boards :) and immersion gold for free.
