UART for Arduino pro mini based Arduino UNO
I waste about two days for uploading sketch into Arduino pro mini by Chinese USB To TTL. I've been angry! But I've been stupid! For uploading into Arduino pro mini necessary DTR-pin. Unfortunately my USB To TTL have not DTR-pin. :(
I've resolved my problem using Arduino UNO. Don't forget pull out Atmega from UNO!!!
