i have made usb to uart coverter with ft232rl but a had few problems abouth it. first capacitor C3 stared smoking a burning after connecting to pc
. then i realised that pin 4,5 on IC are connected together. could this be reason why the cap died? anyway after desoldering this cap and disconnected those pins, i conncted this circuit to PC and drivers installed, It made new port (COM7) and it seemed like it's working. when i connected it to the arduino on my breadboard i couldn't upload sketch. after compiling it reseted arduino but it showed error and didn't upload. Is there anything wrong with schematic or something else? Can someone help?
