Arduino Pro mini to CH340G Connection problem I have worked with Arduino UNO but recently I bought a new Arduino Pro mini 5v 16M and a CH340G converter to work with. I have searched google to connect pins but I found examples that explains this way :
GND to GND
VCC to VCC
Converter RDX to Arduino Pro Mini TXO
Converter TDX to Arduino Pro Mini RXI
My problem is that my Arduino Pro Mini (328p) has pins TXD and RXD (not RXI , not TXO) or maybe I have no knowledge about TX,RX, IN and OUT.
Can someone please help me to connect these wires?
try reversing the tx/rx lines, if the PRO Mini and serial adapter are chinese, you may want to try using your UNO as ISP programmer. See here for a hint/ex:
