I couldn't get the UART to work, but I have a cp210x dongle which works with arduino very well. I connected TX to RX and RX to TX and GND. I connected oscilloscope and saw the signal is very messy and going up to 6.2V what is going on? https://1drv.ms/i/s!AmDLImexgdZ6oAQv0d-BkhHxODiu https://1drv.ms...
