Hi, I am trying to program my new arduino pro mini (copy) and I pluged it in the usb port with a CH340 usb-serial adapter. The usb serial is recognized by my pc but when I try to put data on the arduino it is not in sync. I already chose the right board, chip and port (the port of the usb-serial adapter) but nothing works... am I doing something wrong? tired of seraching and this is my firs arduino project, I'm super newbie
PD: there is no arduino pro mini or pro or whatever port COM in device manager and I know it should be... but... what am I doing wrong?
SOLUTION: the USB TX0 connector must go to the RXI connector. and viceversa
TXO (USB) > RXI (BOARD)
RXI (USB) > TXO (BOARD)
