It is UART, 2V. I connected TX0 to CP2102, RX0 to half divider (470 Ohm+470 Ohm) to CP2102. For link: sudo minicom -b 921600 -D /dev/ttyUSB0

Hi!
I just received the orangepi 3G and I can't r run the modem. I guess that modem device into /dev tree will be the same in both models (3G and 4G)
Which device corresponds with the modem for setting it up with wvdial?
