I recently bought CP2102 from aliexpress and I can't upload sketches to arduino. I burned bootloader and it will program normally if it is on arduino uno board, but I can't put it on home made board and upload.
The board that I have made is Nanino. My connection to the board is
TX0 - RX RX0 - TX VCC - VCC GND - GND DTR - RESET via 0.1 uf cap
I tried connecting with TX0 - TX and RX0 - RX, pressing reset button before upload appeared, but still no response from programmer. How should I configure IDE and how can I test programmer to make sure it's working properly. I have one Mega and Uno at home, so I can test it with thoose to if needed. Thank you very much
have a nice day :)
